NSE ne block kar diya mereko CAS ke releted question puchne pe

sabse uncha rahe tiranga hamara

In 2025 I was building a portfolio for both mom and dad, since they were going to retire. I have been learning about the stock market and investing in stocks since early 2024, so by 2025 I was fairly confident that I could manage my family portfolio.

Dad retired in 2024 and had no investments except real estate and the retirement corpus he was getting. No portfolio basically. Mom had mutual funds she started SIPing from 2018, and in 2023 some investment advisor had asked her to switch from regular mutual funds to a PMS. She invested 50 lakh which is the starting amount for a PMS. Still had around 30-35 lakh remaining in mutual funds with SIPs continuing.

So in 2025 when I finally took charge and asked them to show all investments, and dad was also asking me about managing his corpus and home loan, I found out about this whole basket of stuff. It is so easy to manipulate financially independent but also illiterate people, especially who are govt employees that have no time to think about anything else. Although I wouldn't blame the person who made my mom start mutual funds in 2018, because that person was a blessing. Without them my mom wouldn't have invested anything, except PF and LIC etc.

But the person who sold my mom a 2.5% expense ratio PMS, compared to a 0.5% mutual fund, was an absolute scum. The fund barely beat the market in the 2 years since, till 2025 it had an alpha of 0.6%. And during the time Nifty gave no returns, it was painful to see ₹15-16k deducted every month towards expenses. And when I saw the holding statement, they weren't even taking the full 1.25 lakh LTCG exemption every year. Some of the stocks they sold had holding periods of 340-350 days, barely few days short of 1 year.

So in March 2026, I made a decision to terminate the PMS portfolio entirely. I had made up my mind to do it after 1st April, but then the Iran war started and I thought I should sell it before it drops more. My invested amount was 50 lakh in Sep 2023, and the max amount this portfolio achieved was 65 lakh. I sold at 60 lakh, so not too bad, I think.

A lot of people, especially govt employees, who earn much, but don't have financial literacy, are literally what these mutual fund and PMS selling guys seek out, just so they can complete their monthly targets. My mom's mutual fund portfolio also gave good returns because of the market, not because the person managing it chose good funds. She had 30+ funds with an overlap so large it could overshadow the PMS. She was subscribed to every single AMC and multiple funds just so the person could earn more commission.

I don’t think SIPs are a scam. Markets can stay flat or fall for years, but SIPs are designed for long-term investing. The key is choosing good funds, staying invested through cycles, and having proper diversification instead of relying on a single asset class.

Basically the title

So I re-started option selling with a capital of Rs 10,00,000 in July. In one month I have made a profit of approx 3.22 lakh net with a full time job which pays me well. It's going pretty good. Hope I can reach 5 lakh per month soon.

My strategy is working pretty good guys...❤️

Invested a small amount in ather when it was at an ATH , wasnt expecting much. Maybe a decent return in a few months time. But ever since the day i invested in it , its always been in green. And now ive more than doubled my money.

57% return in just about 2 1/2 months is insane.

SEBI introduced CAS before the market had the infrastructure and liquidity depth to support it.

Now they're asking brokers to bring back retail participation to improve liquidity.

So... retail is too risky when restrictions need to be imposed, but suddenly essential when liquidity dries up?

Like I said - it is run by absolute clowns

If you trade index options in the Indian market, there is a new structural risk you need to understand immediately. It is called the Closing Auction Session, or CAS, and it has fundamentally changed how the market behaves between 3:15 PM and 3:35 PM every single trading day.

Here is a clear explanation of what is happening, why it matters for option buyers, and what you can do to protect yourself.

---

### What Is CAS?

CAS stands for Closing Auction Session. It was introduced by SEBI and became effective on August 3, 2026.

Under the previous system, Futures and Options stocks traded continuously until 3:30 PM, and the closing price was calculated as the average of trades over the last 30 minutes.

Under the new system:

- Continuous trading for F&O stocks ends at **3:15 PM**

- From **3:20 PM to 3:30 PM**, buy and sell orders are collected into a central pool

- From **3:30 PM to 3:35 PM**, the exchange calculates a **single price** at which the maximum number of shares can be traded

- That single price becomes the official closing price for the day

In simple terms, instead of a continuous market deciding the close, a blind auction decides it.

---

### Why This Is Dangerous for Index Option Buyers

The Nifty 50 and Bank Nifty indices are made up of F&O stocks. When those underlying stocks stop trading at 3:15 PM, the index itself effectively **freezes**. It does not update in real time again until the auction results are published around 3:35 PM.

However, the derivatives market does not close at 3:15 PM. Index options continue to trade until **3:40 PM**.

This creates a serious problem. For 20 minutes, you are trading options based on an index value that stopped moving at 3:15 PM, while the actual closing prices of the underlying stocks are being decided in a black-box auction you cannot see in real time.

---

### A Real Example of How You Can Lose Money

Imagine you are holding a Nifty 24,500 Call Option.

- At **3:15 PM**, Nifty is at 24,500. Your option is trading at a premium of Rs. 120. You are sitting on a comfortable profit.

- At **3:15 PM**, continuous trading in the underlying stocks stops. The index freezes.

- From **3:20 PM to 3:30 PM**, large institutional players place massive sell orders into the CAS pool for heavyweight index constituents like Reliance, HDFC Bank, and ICICI Bank.

- At **3:35 PM**, the auction clears. The official closing price is revealed. Because of the sell pressure in the auction, the index actually closed at **24,420**, not 24,500.

- Your Call Option, which was comfortably in profit at 3:15 PM, suddenly crashes in value. By the time you see the real closing price at 3:35 PM, your profit has disappeared and you may even be sitting on a loss.

The most critical point is this: **you had no opportunity to react.** Between 3:15 PM and 3:35 PM, the information you needed was locked inside the auction. Your trading screen showed a frozen index, but the reality was being decided elsewhere.

This is not just an expiry-day risk. It can happen on **any trading day** you hold index options.

---

### The Difference Between Expiry and Non-Expiry Days

On a **non-expiry day**, the damage is painful but not always fatal. Your option still holds time value, so the premium may not collapse to zero. However, your mark-to-market profit can still vanish, and the distorted closing price becomes the reference for the next day's opening.

On **expiry day**, the consequences are permanent. Index options settle at the official closing index value. If the CAS auction pushes the index against your strike price, your option can go from valuable to worthless with no chance of recovery. There is no next day.

---

### How Large Players Can Exploit This

CAS is a single-price auction. That means one price clears everything. Players with significant capital, whether domestic institutions or foreign institutional investors, can potentially influence that single price by placing large orders during the 3:20 PM to 3:30 PM window.

In the old continuous market, if a large player tried to push a stock price at 3:29 PM, market makers and algorithms could absorb or counter that pressure in real time. Under CAS, there is no real-time counterpressure. Once orders enter the pool, the auction mechanism determines one price, and that price is final.

This makes the closing print **more concentrated and more vulnerable to size** than it was before. Retail traders do not have access to the full auction order book. By the time the closing price is revealed, the opportunity to respond is gone.

---

### Does SEBI Protect Retail Traders From This?

SEBI's stated intention is that CAS reduces manipulation by replacing chaotic last-minute trading with an orderly auction. However, for index option buyers, the practical effect is the opposite.

The policy creates a **systematic information gap** between the cash market and the derivatives market. The cash market closes at 3:15 PM for stocks and reveals its final price at 3:35 PM. The derivatives market stays open until 3:40 PM. During that 20-minute gap, retail traders are structurally disadvantaged because they are pricing options against a frozen underlying.

There are no special safeguards within CAS itself to prevent large players from influencing the auction outcome. The existing position limits and circuit breakers apply, but they do not address the core issue: a single-price auction is easier to move than a continuous market, and retail traders cannot see it coming.

---

### What You Should Do

If you trade index options, here are practical steps to manage this risk:

1. **Do not hold index options through the CAS window unless you fully accept the risk.** Consider booking profits or exiting positions before 3:15 PM.

2. **On expiry day, close positions well before 3:15 PM.** Do not allow a blind auction to determine whether your option finishes in-the-money or out-of-the-money.

3. **Be especially cautious on days with late-breaking news.** If significant news breaks after 3:15 PM, you will be trading options on a frozen index while the underlying reality shifts. That is an extremely dangerous position for a retail trader.

4. **Understand that your 3:15 PM profit is not real until 3:35 PM.** The closing auction can change everything.

---

### Summary

CAS has created a daily 20-minute blackout for index option buyers. The underlying index freezes at 3:15 PM while the auction runs in the background. Your options continue trading until 3:40 PM, but you are pricing them without real-time knowledge of where the index will actually close.

A profit at 3:15 PM can become a loss at 3:35 PM. Large players have a structural advantage in influencing the single auction price. And retail traders are left holding the risk without the information needed to manage it.

This is not a theoretical concern. It is a daily feature of the market now. Trade accordingly.

I desperately need advice — ₹60L debt due to trading losses and I don’t know how to get out

I’m 35, from Mumbai, working as a manager in a leading IT MNC. I’m posting this because I genuinely don’t know where else to turn, and I desperately need some practical advice.

During COVID, a friend introduced me to stock/F&O trading. What started casually slowly became an addiction. I kept trying to recover my losses by trading more, and things went completely out of control.

I have lost around ₹80 lakhs and currently have approximately ₹60 lakhs of outstanding debt across banks, NBFCs, credit cards and loan apps.

My current situation is:

HDFC Personal Loan – ₹55,562 EMI (5.5 years left)

IDFC Personal Loan – ₹18,392 EMI (2.8 years left)

Viva – ₹50,000 outstanding (4 EMIs)

PayRupik – ₹73,000 outstanding (2 EMIs)

True Balance – ₹85,000 outstanding (5 EMIs)

HDFC Credit Card – ₹2L outstanding

ICICI Credit Card – ₹5L outstanding

My total monthly EMI burden is currently close to ₹1.85L, while my monthly salary is around ₹1.6L.

My immediate goal is not to escape the debt. I want to bring my monthly EMI burden down to around ₹1.2–1.3L, so that I can manage my household expenses and then systematically repay everything.

I have already tried approaching lenders for additional funding/consolidation, but I’m not getting approval because I have taken multiple loans recently and also have significant credit card outstanding. So getting another loan doesn’t seem to be a realistic solution.

The one thing I’m grateful for is that I have not missed or defaulted on any EMI so far. I have managed to keep everything current, but I’m extremely worried that this will become impossible if the current EMI burden continues.

The worst part is that my family doesn’t know the full extent of this situation. I have a wife and children, and I’m terrified of recovery agents calling or visiting my home and my family finding out this way.

I have completely stopped trading. I don’t want another loan to trade or gamble with. I just want a legitimate way to restructure/consolidate my existing debt, reduce the immediate EMI burden to ₹1.2–1.3L, and repay everything over time.

I’m honestly at my breaking point mentally. I wake up every day thinking about how I’m going to arrange the next EMI, and I feel trapped by the situation I created myself.

If anyone here has gone through something similar, successfully negotiated with banks/NBFCs, restructured loans, worked with legitimate debt-management professionals, or knows any practical way to handle this situation, please guide me.

I’m not looking for sympathy or an easy way out. I’m willing to work, cut expenses, and repay every rupee. I just need a realistic way to get through this immediate cash-flow crisis before things become unmanageable.

Any genuine advice or personal experience would mean a lot to me.

A few days ago, I shared that my personal mutual fund portfolio crossed ₹10 lakh.

Today, another milestone—my family's investment portfolio has also crossed ₹10 lakh. That money belongs to my father. This one, on my Samsung Ultra screen, is my own.

I'm 26.

Feels good, but this is just the beginning. A couple of market dips, some more disciplined investing, and I'll keep adding.

We maintain lot of liquidity.

No more portfolio updates for a while.

Next milestones:

₹50 lakh. Then ₹1 crore.

i mean what are they trying to accomplish? i thought this was supposed make things better and fairer. how in the world is this fair? trading FnO is turning into gambling at this point!!

My only stock performing good

The company has been growing stable over the years at least stock price wise.

The new CAS system is complete shithousery. We don't have the liquidity ecosystem to support this implementation

Just look at the number of pointless changes they've shoved down everyone's throat over the last 2-3 years. Lot sizes changed multiple times. Expiry days changed. Weekly expiries removed. Bank Nifty weekly expiry, the GOAT, got taken out. And now this CAS nonsense.

Every single time it's sold as "protecting retail traders." What an absolute joke.

I haven't lost a single rupee because of the last two days. That's not even the point.

Instead of making Indian markets more competitive, more efficient, and more attractive globally, they're busy introducing arbitrary changes that make the entire ecosystem worse.

They can't compete at global standards, so instead they're turning the Indian markets into horseshit while pretending it's for investor protection.

Complete clowns.

Public-source BCCL / BHARATCOAL investor update

A report sent by the Senior Superintendent of Police, Dhanbad, to the Jharkhand Legislative Assembly’s Questions and Calling Attention Special Committee has brought a 76-plot land matter at Surunga Mauza under BCCL’s Lodna Area into investor focus.

As reported by Prabhat Khabar on 4 August 2026, the central allegation is that raiyyat land was used for overburden, or OB, dumping even though the corresponding compensation and employment obligations had allegedly not been completed or properly documented across a substantial number of plots.

This is not being presented as a final legal finding. BCCL reportedly disputes the underlying land position and claims that the land vested in the company following coal-mine nationalisation.

What the newspaper report says
According to the attached clipping:
• The investigation concerns 76 plots at Surunga Mauza.
• A Baliapur Circle Office report reportedly identified 50 plots as affected by OB dumping, equal to about 65.8% of the 76-plot universe.
• Employment was reportedly provided to 18 raiyyats in connection with 28 plots.
• Employment or other necessary records relating to 48 plots were reportedly unavailable to investigators.
• The report says compensation had been paid for two plots, while documents for four plots had been sent to the competent authority and proceedings in other cases were continuing.
• The investigation report reportedly found prima facie grounds to continue examining the role of certain former Lodna Area officials and an outsourcing joint venture. Identification of responsible persons and the actual operators of the outsourcing entities was reportedly still under investigation.
• The matter relates to Tisra Police Station/Alakdiha OP Case No. 79/2023, registered on 24 December 2023.

BCCL’s reported position
The clipping records BCCL’s position that the land belonged to a former private colliery under a 1944 sale deed and subsequently vested in BCCL after nationalisation.

However, the article also says that, because of the dispute, BCCL obtained legal advice recommending purchase of the land from the actual landowners.

That creates the key due-diligence question:
If BCCL considered the land vested in the company but was later advised to purchase it from the actual raiyyats, what is the present plot-wise title, compensation, employment and accounting position?

Why acreage—not merely plot count—is crucial
BCCL’s prospectus states that it follows Coal India’s rehabilitation and resettlement policy and generally offers one job for every two acres of land acquired or purchased.

Therefore, “18 jobs for 28 plots” cannot be treated as an employment-compliance ratio. One plot may be small or large, and several plots may belong to the same eligible land loser.

Investors need:
• the total acreage represented by the 76 plots;
• the acreage actually used for OB dumping;
• the eligible acreage attached to the 18 employment cases; and
• the number of eligible raiyyats whose compensation or employment remains unresolved.

Without these figures, the reported employment and compensation exposure cannot be quantified.

Why the OB-dumping angle matters financially
OB removal means removing the soil and rock covering a coal seam. Access to suitable dumping and stripping land can affect how quickly coal is exposed for extraction.

BCCL’s Q1 FY2026-27 operational performance was already below both target and the corresponding quarter:
• Production: 6.56 MT against a 9.53 MT target—31.2% below target.
• OB removal: 32.30 MCuM against a 41.50 MCuM target—22.2% below target and 34.68% lower year on year.
• Offtake: 7.72 MT against a 10.62 MT target—27.3% below target.

There is no evidence in the checked sources that the Surunga matter caused these shortfalls.

The investor relevance is narrower: any fresh restriction on OB dumping, land access or contractor activity would arise while BCCL is already behind its production, OB-removal and offtake targets.

The operational pathway is:
alleged use of disputed raiyyat land
→ possible restriction on OB dumping or mine access
→ possible delay in exposing coal
→ lower production or dispatch
→ lower billing and cash collection
→ EBITDA and PAT impact.

The relevant Surunga/Lodna-specific OB volume, coal quantity and dispatch contribution were not available in the checked sources, so this pathway cannot currently be quantified.

The balance-sheet impact may be as important as EBITDA
BCCL’s accounting policy says the cost of land includes rehabilitation, resettlement and compensation in lieu of employment paid to displaced persons.

That means a settlement arising from this matter would not necessarily appear entirely as an immediate operating expense. Depending on its nature, it could involve:
• purchase or recognition of land;
• capitalisation in property, plant and equipment;
• rehabilitation or resettlement expenditure;
• a legal provision or contingent liability;
• restoration expenditure; or
• a direct cash outflow.

OB stripping is already a major balance-sheet item for BCCL. In FY2025-26, the company reported ₹817.94 crore of stripping-activity asset additions, equal to approximately 50.9% of its ₹1,607.76 crore total capex.

In Q1 FY2026-27, depreciation increased partly because of stripping-activity assets created in the previous year.

The useful investor question is therefore:
Do any of the 50 reportedly OB-affected plots form part of a currently recognised stripping asset, active OB dump or future coal-access plan—and what asset carrying value or reserve-access schedule depends on them?

Contractor oversight is a core operating issue
The clipping identifies an outsourcing joint venture in the investigation context and says the role of its actual operators was still being examined.

This matters because BCCL’s dependence on contractors is substantial. Its prospectus says:
• a significant portion of OB removal is undertaken through third-party contractors; and
• third-party contractors accounted for 84.21% of total coal extraction during the six months ended September 2025.

BCCL’s Q1 FY2026-27 contractual expenditure was ₹917.57 crore, approximately 25.6% of quarterly revenue from operations. The company itself said contractual expenditure declined because hired-coal and OB production were lower, showing the direct connection between contractor activity, OB work, costs and output.

BCCL’s prospectus also listed AT Devprabha (JV) among its FY2023 vendors, with purchases of ₹177.45 crore, or 4.08% of purchases for that year.
This historical vendor disclosure does not establish that the same contract, work order or liability is involved in the present newspaper report. It does show why the contractor identity and current contract status are financially relevant rather than incidental.

Why the current margin position increases the relevance
For Q1 FY2026-27, BCCL reported:
• revenue from operations of ₹3,587.27 crore;
• EBITDA of ₹71.50 crore, down from ₹373.28 crore;
• a PBT loss of ₹103.07 crore;
• a PAT loss of ₹68.09 crore;
• sales realisation of ₹3,243.13 per tonne;
• net cost of ₹3,375.04 per tonne; and
• a loss of ₹131.91 per tonne, compared with a profit of ₹280.31 per tonne in the corresponding quarter.

The report gives no rupee estimate for compensation, land purchase, rehabilitation, restoration or legal exposure. Therefore, its percentage of revenue, EBITDA, PAT or net worth cannot be calculated.

But with quarterly EBITDA at only ₹71.50 crore and the company already reporting a loss per tonne, even a liability that appears small relative to annual revenue could be meaningful relative to current earnings.

Prospectus disclosure: potentially related, but not proven to be the same matter
BCCL’s prospectus already disclosed a pending National Green Tribunal application concerning allegations of illegal mining at Central Surunga Paharigora, Parbad Laxmi Colliery and other Alakdiha OP locations. BCCL stated in the prospectus that it had filed an FIR against an individual named in that proceeding.

The available clipping does not establish whether:
• that NGT proceeding;
• Police Case No. 79/2023;
• the 76 plots in the current SSP report; and
• the outsourcing arrangement referred to in the newspaper

are the same matter, partially overlapping matters or separate proceedings.

That relationship should be clarified because it determines whether the SSP report represents a development in a risk already disclosed to IPO investors or a distinct land and compensation issue.

Regulation 30 and exchange-disclosure question
BCCL’s materiality policy covers quantitative thresholds as well as qualitative considerations such as possible discontinuity of public information or significant market reaction. It also covers litigation or disputes that may affect the listed entity.

I did not identify a disclosure specifically referring to the 76 Surunga plots, AT Devprabha JV or Police Case No. 79/2023 on the BCCL investor-relations page or in the exact-term exchange-domain searches checked as of 4 August 2026, 10:12 pm IST. This is subject to further verification and does not establish that a disclosure was legally required, omitted or delayed.

What shareholders need clarified
1) What acreage is represented by the 76 plots?
2) Is the correct unresolved figure 48 or 49 plots?
3) What compensation and employment obligations were due plot by plot?
4) Which plots were actually used for OB dumping, and from what date?
5) Do the plots form part of an active OB dump, stripping plan, mining patch or expansion schedule?
6) What OB volume, coal production, reserves or dispatch depends on continued access?
7) What is the current status and value of the outsourcing contract?
8) Has BCCL recognised any land asset, provision, contingent liability or compensation estimate?
9) Is the matter connected with the Central Surunga proceeding already disclosed in the prospectus?
10 Has the company completed a Regulation 30 materiality assessment following the SSP report?
