Yesterday, positive earnings reports from the old guard of tech companies, Intel (NASDAQ: INTC), Apple and Microsoft (NASDAQ:INTC) poised tech shares for a big session on Wednesday. So far in trading, they haven’t disappointed. Strong earnings for the companies led the technology-laden Nasdaq composite to one of its most successful trading sessions in six months.

Intel (NASDAQ: INTC) rose 6.5%, the most of any of the 30 companies listed on the Dow Jones industrial average after the 29% income for the first quarter. Intel credited greater corporate demand for personal computers for the improvement, dispelling suspicions that the merging tablet would detract interest in desk and laptops.

Apple (NASDAQ: AAPL) was also up today as predicted adding 6.6 points or 2 percent.  Microsoft (NASDAQ: MSFT) was up 2.78 percent.

Much of the sector was buzzing today as  Amphenol (NYSE:APH) posted the most impressive gain of any company in the S&P 500 index following earnings reports indicating passive first quarter growth of 31%. The company has risen over 6% in trading over the course of today’s session.

Yahoo (NASDAQ:YHOO), which has been surrounded by negative expectations on Wall Street on an extended basis also improved today, after reporting a 10% rise in advertising was reported. It’s up 5.21%.
