Artificial intelligence players Google and AMD were among the winners on Thursday as US stocks bounced in a move attributed to bargain hunting after losses earlier in the week.
The big gains for both companies came one day after they unveiled new AI offerings, adding positive momentum to chip companies and other tech stocks.
The Nasdaq led the major indices, gaining 1.4 percent to finish at 14,339.
The Dow Jones added 0.2 percent at 36,117, while the S&P 500 gained 0.8 percent to 4,585.

However, analysts pointed to Thursday's gains as a sign investors were capitalising on the pullback.
