Abstract We compare reactions in the prices and trading patterns of common stocks and closed-end funds, which have substantially di¤erent investor clienteles, to the September 11, 2001 terrorist attacks. Even in assets with institutional buying, retail investor trading moved prices signi…cantly lower. Although greater salience has been shown to reduce underreaction to news, we conclude the extreme salience of this event resulted in overreaction. Subsequent reversals were substantially security-speci…c and therefore not due simply to improvement in general sentiment. Consistent with microstructure theory, the speed of reversals depended signi…cantly on the relative quality and availability of information about fundamental values. terrorist attacks.
