NEW YORK (AP) — April was Wall Street’s best month in nine years — offering some of the most powerful evidence yet that maybe, just maybe, the economy is about to begin a turnaround. The Standard & Poor’s 500 index, considered the most reliable measure of the broader market, climbed 9.4 percent in April, its best performance since March 2000, the peak of the dot-com bubble. The Dow Jones industrial average shot up 7.4 percent in April, on top of a 7.7 percent gain in March.- – – -Contact The Daily Reveille’s news staff at [email protected]
