Foreign investors seem to be turning bullish on Indian equities again with more than $1 billion invested in the last week. Goldman Sachs Group Inc. has projected that these overseas inflows could strengthen further as a stable rupee and improving earnings expectations are encouraging global funds to increase their exposure to Indian equities. The renewed interest from foreign investors could help extend the recovery in the benchmark NSE Nifty 50 index, which has climbed about 8% since touching a one-year low in April. Softer oil prices and the rupee's stability have improved expectations for corporate earnings.
