Shares slipped Friday in Asia after a day of dramatic swings on Wall Street that included Microsoft’s worst drop in nearly six years. Oil prices fell more than $1 and the prices of gold and silver weakened. Companies across the market are under pressure to deliver at least solid growth in profits following record-setting runs for their stock prices. Southwest Airlines flew 18.7% higher even though its profit fell short of forecasts. Oil prices slipped after jumping more than 3% on Thursday due to worries about tensions between the United States and Iran, which could ultimately constrict the flow of crude.
