NEW YORK (Reuters) - Nvidia Corp's debut in the club of U.S. companies valued at $1 trillion on Tuesday may have given a boost to a number of portfolio managers who bought in to the stock, according to data revealed in first-quarter hedge fund filings, such as Australia listed boutique investment firm GQG Partners.

Quarterly securities filings known as 13-Fs are backward- looking but show what funds owned on the last day of the quarter and are one of the few ways that hedge funds and other institutional investors have to declare their positions. They may not reflect current holdings, as fund managers may have added or sold shares since then.
