] By Joanne FrearsonLONDON, July 22 (Reuters) - European shares rose on Thursday, reversing earlier falls as banks gained ahead of the sector's stress tests results on Friday, outweighing gloomy comments by U.S. Federal Reserve Chairman Ben Bernanke.

"If we get a few more decent earnings then markets are going to rebound. Although there has been lots of doubts other the bank stress tests, I think the market is looking forward to it and will be happier when it is out."
Investor sentiment was knocked initially after Bernanke said on Wednesday that the Fed is ready to ease monetary policy further if the budding U.S. economic recovery withers and described the outlook as "unusually uncertain." [
