Stocks tried to patch over recent losses but got only part of the job done Thursday. The Nasdaq and the Dow Jones industrial average each rose 0.5%, while the S&P 500 added 0.4%. The IBD 50, though, declined 0.5%. Volume fell narrowly on both major exchanges. Going into Thursday’s session, the Nasdaq and S&P 500 had lost about 3% and 2%, respectively, since April 24, the day of a closing high for the Nasdaq.
