NEW YORK (TheStreet) -- Stocks backed off session highs on Wednesday as a selloff among luxury goods companies undercut the S&P 500's positive run.

The S&P 500 was up 0.5%, the Dow rose 0.51%, and the Nasdaq gained 0.7%.

Michael Kors (KORS) was having a negative impact on fellow luxury goods companies. The luxury accessories brand plummeted more than 21% after issuing light first-quarter sales guidance of $930 million to $950 million, below an expected $1.09 billion. Fossil (FOSL), Kate Spade (KATE), Vera Bradley (VRA), Guess (GES) and Coach (COH) all were trading lower. 

High-momentum tech stocks were the best performers, getting caught up in a broad-based rally. Apple (AAPL), Microsoft (MSFT), Oracle (ORCL) and IBM (IBM) each added more than 1%, while the Technology SPDR ETF (XLK) climbed 0.91%.

Shares of tobacco companies Reynolds (RAI) and Lorrillard (LO) were on watch after a planned acquisition was approved by the Federal Trade Commission. Reynolds must first sell its Winston, Kool, Salem and Maverick brands in order to purchase Lorrillard.

"A test of investors' nerves is likely to stem from a looming steeping of the yield curve, as the Fed opens the door for a future rate hike," said Peter Cardillo, chief market economist at Rockwell Global Capital. "Equities are likely to adjust before liftoff. We continue to recommend being cautious, as a pullback will offer a great buying opportunity."
