Nifty 50 Plunges 1.5% Ahead of F&O Expiry, Key Support at 22,700

The Nifty 50 fell over 1.5% on September 28, forming a long red candle and signaling bearish momentum ahead of the September 29 monthly derivatives expiry. The index faces key support at 22,700; a break below could drag it to 22,500, while sustained gains above 22,800 may target 23,000. Rising US bond yields and a two-month high in India VIX added to the cautious sentiment.
