With 3.3 million shares changing hands today compared to the average 660,000 one has to ask the question WHY? End of Quarter profit taking? OR, is it concern about Zillows 2nd Quarter earnings? With the already announced $7.1M charge in respect of Restrictive Stock Units as a consequence of the departure of a yet unannounced employee in early May? With Zillow Sales & Marketing costs already running high in Q1 the chances are Zillows 2nd quarter earnings will be a massive disappointment, and despite any top line revenue growth the stock price will get hammered as reality sets in that Zillow is massively overvalued and cannot justify its stellar PE ratio.
