Year-to-date gains: 200%
Float Short (as of 7/31): 43%
The well-regarded purveyor of online and mobile real estate information and listings gets no love from the shorts — and you can see their point. Zillow (Z) was barely profitable last year and is forecast to post a net loss for the current year.
Zillow’s stock also looks preposterously expensive. The forward price-to-earnings ratio (P/E) is a stratospheric 154, while the long-term growth forecast stands at just 30%.
That has shorts piling on hard. Nearly 43% of the float — or 5.7 million shares — was sold short as of July 31, down slightly from 6.1 million a month earlier. Meanwhile, the stock has nearly tripled in 2013.
