Large institutional investors often set the tone for the broader market, backed by extensive research and rigorous due diligence that helps them spot opportunities before they gain wider attention. When both foreign institutional investors (FIIs) and mutual funds (MFs) increase their exposure to the same stocks, it is often viewed as a strong vote of confidence in their growth prospects.An ET Markets analysis shows that FIIs and mutual funds simultaneously increased their holdings in 28 common stocks within the Nifty Midcap 150 index over the past six months. The institutional optimism has largely been rewarded, with 17 of these stocks delivering double-digit returns during the period. Among them, 10 standout midcap stocks rallied up to 65% in just six months, supported by rising ownership from both FIIs and mutual funds. Here's a look at these top-performing names and the increasing institutional interest behind them. (Data Source: ACE Equity).
