eBay is a company that understands network effects better than any other, ... Its core business, as well as (online payment system) Pay Pal, have been created and have succeeded by this network effect ? as more users come in, the marketplace grows in value.
Ebay is really fighting for China but there are two entrenched players there already. So eBay had to invest more in China to compete more aggressively for market share.
Ebay put out good numbers. Wall Street had already priced in a possible miss or even lower guidance going forward but that did not happen. Ebay in fact moderately raised expectations. So that's a good thing.
