With uncertainty over the fate of the Greek economy, the US stock market took a steep dive today, and the big tech companies were not immune.

Like other market indexes, the tech-heavy NASDAQ composite plummeted, and while it has partially recovered, it was still down 3.4 percent (82.65 points) at market close.

The Dow also saw its biggest single-day plunge since 1987 today, although it's since recovered some of that loss.

And here's how far a number of prominent tech stocks have fallen:

  • Amazon -- down 1.7 percent
  • Apple -- down 3.8 percent
  • Google -- down 2.2 percent
  • IBM -- down 2.3 percent
  • Microsoft -- down 2.9 percent
  • Oracle -- down 4.1 percent
  • HP -- down 5.1 percent
  • Yahoo -- down 3.5 percent
