The information content of ticker symbol change: Evidence from multiple class shares

This chapter analyzes the market response to ticker symbol change of stocks with non-conventional voting structures (or multiple class shares, MCS). I find a significant drop (increase) in prices and liquidity (short-sale activity) of MCS stocks, with the most severe decrease being reported for the lower-voting class. This evidence suggests that investors revised downward the assessment of MCS stocks. Regression analysis shows that a significant part of the cross-sectional variation of the event-results is explained by firm's agency costs. Overall, the chapter stresses the importance of enhanced market transparency in curbing private benefits.
