Foreign investors have infused nearly Rs 31,000 crore in the Indian equity markets in the last six trading sessions of the month primarily due to attractive valuations, appreciation in the rupee and improvement in macroeconomic indicators. The re-emergence of Foreign Portfolio Investors (FPIs) as buyers contributed to a smart recovery of about 6 per cent in benchmark index Nifty, reflecting renewed confidence in the market. This latest infusion has also helped reduce the overall outflow for March to Rs 3,973 crore, according to data from the depositories. In comparison to previous months, this marks a significant improvement, as FPIs had pulled out Rs 34,574 crore in February and Rs 78,027 crore in January.
