SEBI has announced changes to the Closing Auction Session (CAS), market closing timings, and F&O settlement methodology. These changes will come into effect from December 7, 2026.

Currently, regular trading in stocks covered under CAS ends at 3:15 PM, followed by an auction session until 3:35 PM. Other stocks continue trading until 3:30 PM, while index and stock F&O contracts trade until 3:40 PM.

On expiry days, the final settlement prices for expiring index and stock F&O contracts are based on closing prices determined through CAS.

Here's what will change from December 7:

- Index and stock trading hours: Regular trading in all stocks, including those covered under CAS, will continue until 3:30 PM.

- Closing Auction Session: CAS will be shortened from 20 minutes to 10 minutes, running from 3:30 PM to 3:40 PM. Market and limit orders will be accepted from 3:31 PM to 3:36 PM, followed by only limit orders. The session will close randomly between 3:38 PM and 3:40 PM.

- F&O settlement: The final settlement prices for expiring index and stock F&O contracts will be calculated using volume-weighted average prices (VWAP) from the last 30 minutes of regular trading (3:00 PM to 3:30 PM), instead of CAS closing prices.

- Index F&O trading hours: Trading will continue until 3:45 PM on all days. However, on expiry days, expiring index F&O contracts will stop trading at 3:30 PM, while non-expiring contracts can trade until 3:45 PM.

- Stock F&O trading hours: Trading will continue until 3:45 PM on all days, including expiry days.

We tend to think scams are easy to spot because something will look obviously fake. Often, it’s the opposite.

Scammers can use a real company’s name, copy its website or app, talk about an actual product, and even give you information that’s partly correct. That little bit of truth is what makes the scam believable.

So instead of asking whether something looks genuine, verify it yourself.

If someone claiming to be from Zerodha contacts you, don’t use the links, phone numbers, apps, or contact details they send you.

If you are looking to park cash for the short term, Treasury Bills (T-Bills) are a good alternative to bank fixed deposits.

On shorter tenures (91 and 182 days), T-Bills typically offer higher yields than matching bank FDs.

You can invest in T-Bills directly on Kite under Bids > Govt. Securities. The bidding window is open every week on Monday and Tuesday.

Here is a quick breakdown of how T-Bills work:

T-Bills are issued by the RBI on behalf of the Government of India.

Unlike bonds, which pay periodic interest, T-Bills are issued at a discount and redeemed at face value (₹100) on maturity. The difference is your return.

For example, if you buy a T-Bill at a discounted price of ₹98, you receive the full ₹100 at maturity. The ₹2 difference is what you earn.

If you trade in the markets, you can also pledge 182-day and 364-day T-Bills for collateral margin and are considered cash-equivalent.
