NEW YORK (TheStreet) -- Here are 10 things you should know for Thursday, April 9:

3. -- U.S. stocks on Wednesday closed up after the Federal Reserve's March minutes showed a lack consensus on when the central bank would raise interest rates.

The Dow Jones Industrial Average (DIA - Get Report) rose 0.15% to 17,902.51. The S&P 500 (SPY - Get Report) increased 0.27% to 2,081.90. The Nasdaq (QQQ - Get Report) jumped 0.83% to 4,950.82.
