Ebay surged Friday on the strength of an earnings beat and a guidance upgrade, Ebay's second in a row. Ebay's core Marketplace business has struggled, but its subsidiaries are driving growth. I should have grabbed the pullback to $39 per share, but I totally missed the opportunity. Hopefully it will pull back again, and I can pick it up for $40 per share near its high-volume support. Ebay's guidance upgrade should move the price higher in coming weeks.
