We investigate the impact of the likeability and pronounceability of stock ticker symbols on firm value. Using a unique, comprehensive dataset with hand-collected ratings of ticker symbols, we find that higher likeability of ticker symbols leads to higher Tobin's Q The pronounceability of ticker symbols has a similar but weaker effect. Further evidence suggests that the effect is possibly due to the impact of ticker symbols on stock liquidity or mispricing or both. (C) 2016 Elsevier B.V. All rights reserved.
