U.S. stocks edged higher on Monday despite a drop in crude oil that weighed heavily on Energy stocks. Technology stocks led the rally to ultimately push the start of the week into positive territory. Healthcare stocks and a series of lackluster earnings dragged down the markets on Tuesday, with the pressure from the Healthcare sector continuing on Wednesday because of criticism of drug prices. Technology stocks pushed the markets higher on Thursday with better-than-expected earnings. Existing-home sales rose in September, with total sales up 4.7% from August and 8.8% from September 2014. Impressive earnings from big-name Technology stocks pushed the S&P 500 back into positive territory for the year.
