Updated from 3:30 p.m. EDT

Among the semiconductors, STMicroelectronics(STM Quote) -- which makes components for long-lasting goods in addition to those for computers -- maintained gains, finishing the day up 7.3% at $4.71. Applied Materials(AMAT Quote) also rose, gaining 3.8% to $10.99.

Among the other winners:

Advanced Micro Systems(AMD Quote) rose 1% to $3.17.

Maxim Integrated Products(MXIM Quote) rose 0.7% to $13.48.

Nvidia(NVDA Quote) rose 1.6% to $9.94.

Among the day's less fortunate:

Texas Instruments(TXN Quote) fell 1.3% to $16.43.

Intel(INTC Quote) fell 0.4% to $14.94.
