NEW DELHI: Foreign investors have infused nearly Rs 31,000 crore in Indian equity markets in the last six trading sessions primarily due to attractive valuations, appreciation in the rupee and improvement in macroeconomic indicators. The re-emergence of FPIs as buyers contributed to a smart recovery of about 6% 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.
