$NVIDIA (NVDA.US)$ The stock might also have benefited from bets that Nvidia's weighting in the $70 billion Technology Select Sector SPDR ETF will have to be increased. The ETF is scheduled to rebalance its holdings on June 21, based on stocks' closing prices for Friday. If Nvidia's market value is larger than that of either Microsoft or Apple, it could take their spot as one of the fund's top two holdings, triggering an allocation of more than 20%, from just 5.7% currently.

Currently Nvidia is still on track to miss out on the top two spots, having closed on Thursday at a market cap of $3.19 trillion, about $10 billion behind the other two companies.
