Which factors led to a 1,600-point rise in Sensex today?

Sensex recorded an over 1,600-point rebound on Friday owing to a rise in share prices of IT companies. Value buying at lower levels led to a rally in blue-chip bank stocks, which also contributed to the rise. Nikkei 225 index's nearly 1% rise, Wall Street recording marginal gains and Adani Group firms marking a recovery also aided in Sensex's rebound.
