Interestingly, the broader markets outperformed the benchmark indices. The BSE mid-cap and small-cap indices closed 0.1 per cent and 0.5 per cent down, respectively. However, the market breadth remained largely negative, with 994 stocks advancing against 1,543 posting a decline on the BSE.
Market participants say, whenever high weightage stocks like Infosys or ITC move significantly, they are bound to have considerable impact on the index. However, the market's overall direction of the market would depend on other macro factors and global cues.
"Investors would continue to be cautious about Infosys in the near term. However, the announced buyback is expected to provide some impetus to the stock. But, from an overall market perspective, much will depend on corporate earnings of the next two quarters," said Rakesh Tarway, head of research, Reliance Securities.
The board of directors of Infosys will be taking up the buyback proposal on Saturday. Analysts expect the company to keep the buyback price at a good premium to the market price.
Sun Pharmaceutical and NTPC shares, which fell 3.8 per cent and two per cent, were among the other Sensex stocks that fell the most on Friday. On the other hand, shares of Tata Cosultancy Services, a rival of Infosys, went up 1.2 per cent. Hindustan Unilever was the biggest gainer in the index, with upward movement of 2.1 per cent. Foreign portfolio investors sold equities worth Rs 2,182 crore, while domestic institutions made net purchases worth Rs 585 crore, from provisional BSE data.
The overall global sentiment also remained subdued on Friday, with Hong Kong's Hang Seng and Japan's Nikkei 225 closing a little more than one per cent lower. European markets opened 0.5 per cent to one per cent lower.
"On a year-to-date basis, India has performed well, led by strong liquidity and reform. But, in recent months, inflows from foreign institutional investors have reduced, which mighty impact the performance in the near future. High valuation and lower than expected financial results leading to downgrade in FY18 earnings is a key risk. Given a lack of domestic triggers, the market is likely to perform as per the direction of the global market," said Vinod Nair, research head, Geojit Financial Services.
The trading volumes in Infosys surged significantly due to the news
development. A total of 90.3 million shares of Infosys changed hands across BSE and National Stock Exchange. This is close to 23 times the 3-month average volume in the Infosys stock.
