According to the study, Chinese stocks with lexicographically earlier tickers are traded more frequently, with a backward change leading to a decrease in turnover. This bias is heavier in the service sector and for obscure stocks. Stocks switching to later lexicographic positions are penalized in trading frequency, regardless of alternative financial measures used.
Chinese stocks with lexicographically earlier tickers are traded more frequently. Quantitatively, all else held equal, a backward change in lexicographic position by one standard deviation leads to a decrease in turnover by nearly ten percent. This lexicographic bias is heavier in the service sector and for obscure stocks. It is primarily driven by the initial character of stock tickers. Stocks switching to later lexicographic positions are penalized in trading frequency. Using alternative financial measures leads to the same findings.
