All SaaS got their faces ripped off on Friday. Basically I think it has to do with Google's stock behavior, which has been pretty disastrous. After posting amazing earnings and 20% growth, it is down $130+ in 4 days. Given that performance, people are selling first and asking questions later, which is why LNKD and Tableau got destroyed on Friday, and why other SaaS like Salesforce did as well. For the stocks that haven't announced yet, the sellers are thinking "Well if Google is down $130, and Salesforce won't have Google's numbers, then it's only going to get destroyed so I should sell now."

Looks like the only few strong companies in the Valley right now are the stalwarts like Facebook, and everything else is at risk of getting whacked sooner or later.

To all those that think "The bubble will burst", they haven't been paying attention to the stock market. Tech is down bigtime in the last year, the bubble has already burst. What we're waiting to see if which companies will survive the fallout, ie. lowered VC funding, harder funding rounds, less revenues, etc. The tide has been going out since 2015, and 2016 is the year in which we find out which unicorns were swimming naked and which weren't.
