US stock market: Wall Street jumps with rosy outlooks from companies

US stock market: U.S. stocks rallied on Wednesday, with all three major indexes ending up at least 1 per cent as upbeat outlooks from Micron Technology and other companies eased some worries about the health of the economy.

In a sign of potential further strength, the S&P 500 also closed above its 50-day moving average for the first time since March 6, before the onset of the bank crisis, and the CBoe volatility index (.VIX), Wall Street's fear gauge, ended at its lowest level since March 8.

Micron (MU.O) shares shot up 7.2 per cent, boosting the Nasdaq and S&P 500, and leading gains in the PHLX semiconductor index (.SOX), which closed 3.3 per cent higher.

The memory chip maker late Tuesday forecast a drop in third-quarter revenue in line with Wall Street expectations, while it gave a rosy outlook for 2025 with artificial intelligence boosting sales.

Adding to the optimism, Lululemon Athletica Inc (LULU.O) jumped 12.7 per cent after an upbeat annual results forecast.

"We had a couple of good reads into the economy from a couple of companies," said King Lip, chief investment strategist at BakerAvenue Wealth Management in San Francisco.
