Information and Insurer Financial Strength Ratings: Do Short Sellers Anticipate Ratings Changes?

Abstract: Ratings of financial institutions have been shown to provide informational value as stock prices generally decrease in response to ratings downgrades. Moreover, insurer's stock prices have been observed to decrease 2 days prior to downgrades, suggesting that informed trading occurs during the predowngrade period.

“…In the case of bond rating changes, stock prices move in the direction of the change (positive or negative) during the 12 months prior to the announcement (Holthausen and Leftwich, ; Goh and Ederington, ). Likewise, Wade, Liebenberg, and Blau () find that short‐selling activity is significantly higher prior to insurer rating downgrades. For bond rating downgrades, abnormal negative returns are also apparent in the days following the announcement (Holthausen and Leftwich, ; Hand, Holthausen, and Leftwich, ; Goh and Ederington, ) and can persist for up to a year (Dichev and Piotroski, ).…”

“…Hence, we expect the effect of a drop in analyst coverage to be stronger for more opaque insurance firms than for less opaque insurance firms. We use the variation in opaqueness (Wade et al, 2016;Zhang et al, 2009) to test our third hypothesis: Hypothesis 3. For more opaque firms, the effect of a drop in analyst coverage on firm risk-taking should be stronger than for less opaque firms.…”

“…Based on the research of economists [18][19][20], we can say that in their activities, insurance companies should strive for an optimal combination of the proportion between risk acceptance and capital. To minimize risks, property liability insurance companies resort to reinsurance.…”
