Both Sensex and Nifty closed at record highs today due to the return of tremendous buying in the last hour of the stock market . The BSE Sensex jumped 255.83 points to close at 85,169.87 points. Similarly, the NSE Nifty rose 63.75 points to reach 26,004.15 points. After swinging between green and red marks throughout the day, buying returned in the last hour of the market, due to which both the indices closed in the green mark. If we look at the index, Nifty Bank, Pharma, and Realty saw a good rise. Let us tell you that the major indices of the stock market registered a decline in early trade on Wednesday. 

Profit booking by investors was the main reason for this. In Asian markets, South Korea's Kospi was in loss, while Hong Kong's Hang Seng, Japan's Nikkei 225 and China's Shanghai Composite were in profit. US markets closed with a positive trend on Tuesday. International standard Brent crude fell by 0.28 percent to $ 74.96 per barrel. According to stock market data, foreign institutional investors (FIIs) were sellers on Tuesday and sold shares worth a net of Rs 2,784.14 crore. 

Shares of these companies rose. 

Among the 30 Sensex companies, Power Grid, Axis Bank, NTPC, Bajaj Finserv, Bajaj Finance, Tata Steel, Mahindra & Mahindra, and HDFC Bank gained significantly. On the other hand, Tech Mahindra, Tata Motors, Titan, Kotak Mahindra Bank, State Bank of India, and JSW Steel closed with losses. 

Expectations of volatility in the market 
Vinod Nair, Head of Research, at Geojit Financial Services, said, "After trading in a limited range, the major indices registered gains, led by power and banking sector stocks. On the other hand, the indices of mid-cap and small companies declined due to valuation concerns." He said that the domestic market may face short-term challenges due to the decline in FII inflows and cheap valuations in other emerging markets.
