WINDERMERE, Fla. ( Stockpickr) -- The markets are prepared to close a harsh week on a high note, as traders look forward to the debut of the much-anticipated Facebook ( FB) IPO. A positive showing for Facebook shares could spark a change in the recent downtrend in the U.S. equity markets.The S&P 500 is on a five-day losing streak, having dropped 3.9% over that timeframe. That popular index is now trading near its lowest level since the middle of January. The Dow Jones Industrial Average is also trading near its late January lows, after this broad index has dropped close to 1,000 points during just the month of May. The tech-heavy Nasdaq is now trading near lows last seen in late January, after it has dropped over 200 points in May.
