Why is TCS falling/rising?

As of 26-Aug, Tata Consultancy Services Ltd. is experiencing a price increase, currently at 3,156.25, reflecting a rise of 15.5 or 0.49%. The stock has outperformed its sector by 0.99% today and has shown a consecutive gain over the last two days, with a total return of 3.36% during this period. Despite this positive movement, the stock's performance over the past year has been significantly negative, with a decline of 29.88%. However, the company demonstrates strong long-term fundamentals, including a high return on equity (ROE) of 46.19% and a healthy growth rate in net sales. The stock's attractive valuation, indicated by a price-to-book value of 12.1 and a high dividend yield of 4.04%, further supports its recent price increase.
In the broader market context, TCS's short-term performance contrasts with the benchmark Sensex, which has declined by 1.05% over the past week. While TCS has gained 4.64% in the same timeframe, its year-to-date performance remains underwhelming, with a drop of 22.97% compared to the Sensex's rise of 3.39%. The stock's liquidity remains adequate, although there has been a decline in investor participation, as indicated by an 11.79% drop in delivery volume. High institutional holdings at 23.48% suggest confidence from larger investors, which may help stabilize the stock amidst its recent volatility.
