News@Princeton: The ease of pronouncing the name of a company and its stock ticker symbol influences how well that stock performs in the days immediately after its initial public offering, two Princeton University psychologists have found.

A new study of initial public offerings (IPOs) on two major American stock exchanges shows that people are more likely to purchase newly offered stocks that have easily pronounced names than those that do not, according to Princeton's Adam Alter and Danny Oppenheimer. The effect extends to the ease with which the stock's ticker code, generally a few letters long, can be pronounced -- indicating that, all else being equal, a stock with the symbol BAL should outperform one with the symbol BDL in the first few days of trading.

hmmm, I think this is a short term factor
This directly contradicts "Davies' Law", the iron regularity of stock markets that any stock with a "cutesy" ticker will invariably flame out appallingly or turn out to be run by crooks. The only exception I can think of is SouthWest Airlines which has actually done pretty OK despite having the ticker LUV.
