Abstract: Abstract This paper investigates liquidity shocks on the US corporate bond market around credit rating change announcements. These shocks may be induced by the information content of the announcement itself, and abnormal trading activity can be triggered by the release of information after any upgrade or downgrade. Our findings show that: (1) the market anticipates rating changes, since trends liquidity proxies prelude the event, and additionally, large volume transactions are detected the day before the downgrade; (2) the concrete materialization of the announcement is not fully anticipated, since we only observe price overreaction immediately after downgrades; (3) a clear asymmetric reaction to positive and negative rating events is observed; (4) different agency-specific and rating-specific features are able to explain liquidity behavior around rating events; (5) financial distress periods exacerbate liquidity responses derived from downgrades and upgrades.
