What's in a name? A lot of money

Tampa-based managed health insurance giant WellCare's stock is one of the top performers in the region, with a price hovering around $120 a share.

But it could use some help with its stock symbol.

That's because Wellcare's symbol, WCG, is on a list of the top 100 least likable stock symbols, according to a new study co-authored by University of Alabama finance professor Xuejing Xing. The study, “What's a name worth? The impact of a likable stock ticker symbol on firm value,” was recently published in the Journal of Financial Markets.
