ebay is a lock for 58 a share, internet tax is just a buying opportunity, good companies find ways to work around this and ebay is a good company, actually their balance sheet, et. al. is better thatn starbucks and look where they are. you are safe to buy here and hold till 58
Rolling on the floor laughing what you said, "internet tax is a buying opportunity and good companies find a way to work around this" ~ yeah, usually companies who find ways to work around taxes wind up deflowered with executives in prison. Better to take investment advice from that baby in the e-trade commercials than this monkey.
Internet sales tax on the way, Mastercard to increase fees on Paypal in June (Visa will be just around the corner), increased selling fees May 1st will drive many sellers to Amazon, not to mention, we're coming into summer, which is the slowest retail season. The risk factors for eBay at this juncture far outweigh the potential profits.
Using you're method, say I were to buy 1000 shares at $52.91 or $52,910 ~ hold until $58, take $58,000, that leaves a little over $5,000 profit, minus capital gains taxes and brokerage fees. Hardly worth the risk on a volatile company like eBay.
