Needham is the latest Wall Street giant to crank up Nvidia’s price target, and the jump is big. The firm bumped its price target to $200 from $160, while maintaining a buy rating, following Nvidia’s confirmation that it’s gearing up to resume H20 chip sales to China.

Currently, Nvidia accounts for nearly 8 percent of the S&P 500. That’s the highest weighting for a single stock in 45 years, according to Todd Sohn, senior ETF strategist at Strategas Securities. For context, industrials account for 8.7 percent of the index, while healthcare stands at 9.1 percent.
