Volatility in the stock markets has some Minnesotans watching their investments carefully. In a stomach-churning ride on Wall Street yesterday, the Dow Jones slid over 400 points before climbing back and finishing the day with a loss of just 45. The Nasdaq was down more than 58 points before finishing up about 9. Despite mounting evidence of an economic recovery, stocks have been sliding for about two months. Analysts largely attibute that to corporate accounting scandals that have left investors mistrustful of earnings reports.
