In case you haven't noticed, this has been a miserable month for tech — especially for those companies that couldn't find a way to beat Wall Street's expectations.

Just ask Twitter. The social media darling did pretty much everything that analysts has asked. The company more than doubled its quarterly revenues, posting sales of $361 million. Twitter turned an actual profit, albeit a mere penny a share. But that was what Wall Street analysts had been expecting.

Meanwhile, the company reported that the number of active users grew 23%; timeline views (Twitter's equivalent of website page views) increased 80%; and ad revenues from those page views increased 83%. Still, as UBS analyst Eric Sheridan told USA Today, the results lacked "upside surprise."

The result: Investors pummeled the stock, which lost more than 10% of its value in after-hours trading Monday.

And the day before that, Netflix announced it attracted far fewer new U.S. members for its streaming video service than was previously estimated. That was enough to erase more than a fifth of the company's market value:
