Seems sensationalist. If you look closely, the dow was down 7%. aapl's beta is 2.37, so we'd expect apple to fall 17%. goog's is 2.07 for 14.5%. yhoo's 1.19 gives 8%

since the market lost so much money last night, how badly are the tech giants fairing against expectation? aapl:-4% goog: 3% yhoo:-3%

so, either Oh NOES! teh sky is falling! or tech stocks are more sensitive to market activity.
