Wall Street recorded the best week for 2010 and hopes that Ben Bernanke, the Federal Reserve Chairman, will provide a reassuring assessment indicating the last improvement.

The rate rise implied that the monetary sector is recovered enough, creating the conditions for taking back remarkable liquidity, offered by the Fed. The Fed claims its benchmark fed funds rate will stay very low in the next period to sustain the recovery, without to clarifying the timeline of their exit strategy.

It is difficult to say if this improving level is an expression of its confidence in the financial recovery or a reflection of their concern about inflation. Earnings from main suppliers will remain in the focus, combined with essential financial data. It is difficult to regenerate the investors optimism as long as the consumer spending accounting is around 65% of U.S. activity.

Different growth-oriented stocks were increasingly targeted by investors looking for beaten-down shares like technology or commodities, helping the S&P 500 score the largest weekly progress since November. It climbed 3.1%, the Nasdaq gained 2.8% and DJI rose 3%.

According to the chief U.S. equity strategist, Thomas Lee, the release of positive information during the last quarter caused stocks to improve. Ben Bernanke will testify Wednesday and Thursday before different officials.
