Technology led market gains on Wednesday as the S&P tech sector hit its highest level since November 2000 and the Nasdaq 100, another indicator of industry growth, reached a 14-year high.

The S&P tech sector is the only division of the index that traded at a 52-week high on Wednesday morning. Companies leading gains at 52-week highs included Qualcomm, Hewlett-Packard, EMC Corporation, and Amphenol.

Programmable devices company Xilinx was the greatest laggard.

One analyst warned of a tech bubble.

"[It's a] tale of two worlds between old tech and new tech," said Chad Morganlander, portfolio manager at Stifel Nicolaus. "At this point of the market cycle I would avoid momentum stocks and move up the quality spectrum."

He added that new firms in the sector "can walk the walk, but valuations are too rich for my blood."
