SEBI Sets Tuesday and Thursday Expiry Days for NSE, BSE
Imagine stock trading, where agreements called 'derivatives' have deadlines.
The boss of these markets, SEBI, decided to change those deadlines.
Now, one market (NSE) will have deadlines on Tuesdays, and another (BSE) on Thursdays.
This helps traders spread out their actions and potentially reduces big price swings.
NSE wants the Tuesday to help its market position.
This also aligns with global practices, allowing more time for investors.
SEBI assigned Tuesday as the expiry day for NSE derivatives and Thursday for BSE.
Changes are effective from September 1st for new contracts, existing contracts remain unchanged.
SEBI aims to reduce volatility spikes by spreading out expiry days.
NSE seeks to benefit from a Tuesday expiry with more time for trader decisions.
BSE may gain from a Thursday expiry aligning with global market practices.
