Capital Gains Tax on Shares in India
The mechanics that do not change with each Budget: holding periods, how a gain is computed, set-off and carry-forward of losses, and where rates must be checked.
The Protective Put
Insurance on shares you own, costed honestly. How the floor is set, what it costs per year, and why long-term investors should rarely buy it continuously.
What Is a Demat Account?
Demat and trading accounts are held by different parties. Where your shares really sit, what a broker can and cannot do, and what happens if one shuts down.
Delisting of Shares in India
Voluntary and compulsory delisting work very differently for a shareholder: how the exit price is set, what happens if you miss it, and why suspension is a trap.
Bull Call Spread and Bear Put Spread

Circuit Limits, ASM and GSM
Price bands, what a locked circuit actually means for an exit, and how the surveillance framework changes the rules on a stock without the company doing anything.
How to Verify a SEBI Registration
What each category of registration permits, how to check a number against the public register, and where advice ends and distribution begins.
Rollover in Futures and Options
Closing the near series and opening the next is two transactions, not one continuation. What it costs, when it is sensible, and what rollover data does not tell you.
