(Retail sales article updated with analyst commentary.)NEW YORK ( TheStreet) -- Retail sales inched up 0.3% in February, boosted by electronic sales. Sales hit $355.5 billion, according to the Commerce Department. Analysts expected sales to be unchanged from January. But January sales were revised lower to a 0.1% gain from the 0.5% increase previously estimates. February marks the fourth consecutive month the figure has increased. On a year-over-year basis, retail sales jumped 3.9%. "February could be the direct result of cabin fever with consumers eager to get some fresh air and enjoy a day of shopping," NRF Chief Economist Rosalind Wells said in a statement. "We expect sales increases to continue, but high unemployment and other economic factors will restrain consumers' ability to splurge on discretionary items." Most of the sectors reported gains, except for auto and truck sales, which fell 2%. Electronics and appliances saw the biggest increase, spiking 3.7%. Sales at general merchandisers grew 1%, department stores jumped 1.1%, clothing stores rose 0.6% and food and beverage was up 1.3%. This data, however, doesn't come as much of a surprise after last week's better-than-expected same-store sales numbers. American Eagle Outfitters ( AEO), Macy's ( M) and Abercrombie & Fitch ( ANF), among others, all significantly topped expectations. -- Reported by Jeanine Poggi in New York.
