These 3 states house the 'ugliest' S&P stocks

Just about every state can brag about its good looking stocks, especially Idaho and Connecticut. But some states are having a tougher time finding the fairest of the land.

Shares of companies based in three states, South Carolina, Arizona and Louisiana, are posting average gains of less than 10% over the past year, according to a USA TODAY analysis of data from S&P Capital IQ. The universe is limited to stocks in the .

True, a 10% gain might not sound that bad, until you realize that the Standard & Poor's 500 is up roughly 19% over the same time period.

When it comes to ugly, South Carolina is the champ. The average return of the state's stocks is 3.5%. That's because the state is home to just one S&P 500 stock, utility SCANA, which is seeing its shares lag the S&P 500.

Investors who want to see states with more companies in them before pronouncing them ugly might consider Arizona as a contender. The state is home to six S&P 500 companies, and those stocks are up just 9.5% over the past 12 months on average. The biggest loser in Arizona has been Murphy Oil, which has seen its shares sink 1.4%.
