Online Sales are Growing Very Nicely
I guess there is a reason why many of the on-line merchants have seen huge stock run ups. (article) Online retail grew by 33% in the UK, and the activity in the UK is a good measure of what is to be with in the US. And the nice quarterly reports of AMZN and other merchants is a sign of this.
With the solid numbers, the short got caught with their pants down and were served. I do not think current prices are merited, but the numbers suggest a better overall financial picture toward online retailers.
