After a two-day plunge, stocks ended the week with an advance Friday, suggesting Wall Street may be successfully weaned from the Fed’s easy money after all. But that gain wasn’t enough to erase the market’s loss for the week. Stocks have now fallen two weeks in a row, and four of the past five. The real question will be whether the sell-off continues next week, analysts said. Many investors have been predicting some kind of pullback in the market following its nearly unbroken advance since last fall. The S&P 500 index rose for seven straight months through May. So far in June it’s down 2.1 percent.
