Analysis-Funds punished for owning too few Nvidia shares after stunning 230% rally

Nvidia Corp’s soaring rally has thrilled investors this year – except for the sizeable number of fund managers who avoided what they believe to be an expensive stock. Across nearly 330 mutual funds benchmarked to the S&P 500 or a similar index, only 15% held an above-index weight in Nvidia, according to a Morningstar analysis of the funds' most recent regulatory filings. Among those funds that held a below-average weight in Nvidia, 85% underperformed the index so far this year, Morningstar's data showed.
