New York Stock Exchange traders are wonderingwhich way a volatile financial market will move in the upcoming months.Low oil prices combined with less demand around the worldhave weakened American stock prices.By the close of trading last week,the Standard and Poor's 500 was down more than 6 percent this year.But the S&P 500 Index rose 2.8 percent on Fridayto rebound from a New Year's slump.On Monday, the S&P 500 was up 27 points to close at 1,945.The Dow Jones Average, the main measure of major American stocks,rose 228 points to close at 16,620.Wall Street traders and analysts are looking at factorsthat would keep the market in the positive.But for now, Wall Street watchers expect extreme ups and downs.The term "choppy trade" is used often now on Wall Street.A choppy market occurs when prices swing up and downwith no major price movement in either direction.NYSE's Peter Costa said:"I think there is more volatility in these marketsWhat you may see is choppy trade with200- to 300-point swings in the Dow,and 40 in the S&P 500 ...for at least the next couple months."This week is an important one for the market.Financial reports on consumer spendingshould be released by Target, Macy's, Home Depot and Lowe's.The Consumer Confidence report is set to be released Tuesday.American retail leader Wal-Mart recently reported earnings below estimatesand lowered its full-year sales guidance.Consumer spending is a key factor to watchas the fourth-quarter earnings season comes to a close,said market analyst Lindsey Bell.Another sector traders will contend with this weekincludes a gross national product report Friday.
