RC: The Efficient Market Hypothesis says the market reacts to new information and prices reflect that information.

The quick and accurate reaction to information is one aspect [to the Efficient Markets Hypothesis]. Another aspect is nonreaction to noninformation. The fact that Greenspan is giving a speech is not really new information. But we get a reaction an hour ahead of time. That's the puzzling part. That undercuts, to some extent, the Efficient Markets theory; it creates some concern.
