A mix of luxury brands and discounters reported quarterly earnings that topped expectations, results that underscored a broader report showing U.S. retail sales broke three consecutive months of declining growth in July as consumers regained some semblance of confidence this summer.

Strong results issued on Tuesday by Michael Kors Holdings Ltd (NYSE: KORS) and Estee Lauder Companies Inc (NYSE: EL) were the latest signals of strength in high-end brands, which confirms that wealthy shoppers are still buying despite lingering concerns about the global economy.

Discount retailer The TJX Companies, Inc. (NYSE: TJX), owner of the Marshalls and T.J. Maxx chains, saw an influx of shoppers seeking inexpensive designer products in the second quarter, which prompted the company to raise its full-year profit forecast.

Retail sales surged 0.8 percent in July, the Commerce Department said Tuesday. This was the biggest gain in sales since February and topped expectations of a 0.3 percent gain. The sharp increase suggests that, after three months of holding back on spending, consumers loosened their purse strings.

Even after the slight downward revision to June's figures, the level of retail sales in July were back to where they were in May.

Details of the report were also strong, with monthly sales rising across the board.

Consumers increased spending on general merchandise with department store sales up 0.6 percent and non-store retailers posting a solid 1.5 percent gain. Sporting good sales also up 1.6 percent, clothing up 0.8 percent and electronics gained 0.9 percent. The gain in non-store retailers, which capture internet shopping, has been impressive over the past several years, up over 15 percent this year. 

"Despite high unemployment, and political and fiscal uncertainty, consumers are spending again, albeit cautiously," Jack Kleinhenz, chief economist of the National Retail Federation, said in a note. "Retail sales continue to remain resilient in the face of bleak international news, with retailers on track with sustained sales growth year-over-year and year to date. Retail sales will continue to see modest growth in the fall and winter."

Economists pay close attention to retail sales, which account for about two-thirds of demand in the U.S. economy. Following weak readings throughout the second quarter, July's retail sales figure represents a strong start to the third quarter.

After the release, Bank of America added 0.4 percentage points to its third-quarter GDP growth forecast, and is now tracking 1.7 percent for third-quarter GDP growth.

However, Tuesday's solid retail sales report might have dashed any hopes for a fresh round of quantitative easing at the September meeting of the Federal Reserve's Federal Open Market Committee.

"While this is certainly far from healthy growth, it is also clearly not at recession levels either," Bank of America economist Michelle Meyer and her team wrote in a note to clients. "Combined with the solid payroll report for June, today's retail sales data further reduces the likelihood of QE3 in September but does not take it off the table.

"All eyes are on durable goods next week and July payrolls in early September. Today's data may have bought the Fed some time," Meyer said.
