Earnings from Yahoo ( YHOO ) and Intel ( INTC ) set the stage for a market decline. The market recouped more than half of the losses from Monday's big selloff. The Dow Industrials rallied 150 points, the S&P 500 gained 21 and the Nasdaq rose 48. Yahoo's earnings rose 36 percent from a year ago, but the company's new management team remains under pressure to prove that its turnaround plan is working. Investors are concerned about a drop in revenue from display ads. Analysts say the company is losing advertisers to Facebook ( FB ) and Google ( GOOG ). Yahoo shares, up 20 percent so far this year, are set to slide this morning. Declining sales of PCs continue to drag on Intel. Its net fell 25 percent. The company has been trying to grow its business of selling chips for servers and mobile phones, but personal computers still account for the bulk of the company's revenue.
