Knee-deep in the third earnings season of 2015, the stock market just finished a disappointing week. From Monday morning to Friday night, the S&P 500 index fell 1.3%, the tech-heavy Nasdaq Composite market barometer lost 1.7%, and the Dow Jones Industrials index dove all the way to a 1.8% haircut.

But some tech companies were dealt an even tougher hand this week, and their stocks fell 12% or more.

It's a tale of three earnings reports. Both Universal Display (NASDAQ:OLED) and Twitter (NYSE:TWTR) fell roughly 13% this week -- one on a fresh quarterly report and one still swooning on bad news shared last week. InvenSense (NYSE:INVN) plunged 15% lower, but only after first rising more than 6% in anticipation of good tidings that never arrived.
