Indian Stocks Tumble: Sensex Drops 721 Points Amid Market Concerns

The stock market went down because investors were selling stocks.

The Sensex and Nifty, which track the performance of many companies, fell to their lowest point in a month.

This happened partly because of poor results from some big companies and because investors were worried about what's happening in other countries' markets.

Also, foreign investors sold a lot of stocks, although some local investors bought them.

Despite the market's fall, India and the UK made a trade deal that could help boost their economies.
