4TH QUARTER WORRYING RETAILERS
Although shoppers were much in evidence on Saturday, many of the nation's merchants, after a difficult Christmas season, are facing the final month of their last 1981 fiscal quarter with discomfort. More than a few believe it will show the scars of erratic sales and the costly markdowns taken during the first four weeks of December. The outlook for the fourth quarter, which for retailers ends on Jan. 31, is cloudy, a special source of concern since the period normally provides more than 50 percent of the year's profits and 30 percent of sales. But most analysts see the quarter's results as unchanged or down from the 1980 quarter. They also see it as an uncertain harbinger for the early months of the new fiscal year.
