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%<p>since the market lost so much money last night, how badly are the tech giants fairing against expectation?
aapl:-4%
goog: 3%
yhoo:-3%<p>so, either Oh NOES! teh sky is falling! or tech stocks are more sensitive to market activity.
