Tech beat trade war in markets

U.S. stocks rose Friday as biotech shares drove gains. The dollar extended losses and Treasuries climbed despite the mixed jobs report and the impact of an escalating trade rift with China.

All major U.S. equity benchmarks were higher. The S&P 500 Index rose, clinching its biggest weekly increase in a month. Nasdaq gauges jumped by more than 1 percent with biotech firms, chipmakers, and software and tech hardware companies leading.

Volume was soft, with S&P 500 stocks 23 percent below normal and Dow Jones industrial average shares 32 percent off their daily average. The dollar was lower, and Treasuries rose.
