Information Spillovers and Cross Monitoring between the Stock Market and Loan Market

Abstract

We explore information spillovers and cross-monitoring between the stock and loan markets, focusing on the roles of short sellers and banks. Using Regulation SHO that directly affects short-selling constraints in the stock market but is exogenous to the loan market, we find that only those firms without bank monitors exhibit significant stock price declines upon the announcement of SHO. We also document that while short interest increases following SHO, it increases far less for firms with bank monitors. Using bank and lending relationship characteristics, we find SHO returns increase in the bank’s ability and incentive to monitor. Our exploration of equity ownership structure reveals that the presence of block holders and dedicated owners has little to no effect on our results, suggesting that bank monitors complement shareholder monitoring efforts.
