Investors might want to rush to the door after the Netflix post-earnings spike, said CNBC "Fast Money" trader Steve Grasso.
The streaming media company jumped 11 percent in extended trading after missing Wall Street's first-quarter earnings expectations but beating projections for both U.S. and international subscriber growth. At nearly $530 per share, Netflix owners would be wise to take profits, Grasso noted.
"You have to sell on this type of move. You cannot keep it," he said.
Trader Tim Seymour said international user growth—which came in at 2.6 million versus 2.3 million expected—impressed him. However, he noted the valuation put traders in a "very difficult place."
He added that $500 per share could become a new floor for the stock. Trader Guy Adami added that shares seemed "stupid expensive" measured by price-to-earnings ratio, but investors should look beyond the metric to subscriber growth.
Traders also discussed how to play some of Wednesday's other technology movers.
Chipmaker Sandisk plunged 6 percent in extended trading after reporting that first-quarter revenue fell nearly 12 percent year-over-year. It also cut full-year guidance.
Seymour noted that Sandisk raises more red flags than another embattled chipmaker, Micron.
Mobileye, a maker of driver assistance systems, jumped 10 percent Wednesday on positive analyst notes from Morgan Stanley and Deutsche Bank. It closed above $46 per share.
Adami said investors should own Mobileye against roughly $42 per share. However, Grasso noted that the car technology space is starting to getting crowded as Google and other giants develop car technology.
Software company Oracle has "quietly" surged, Adami said. It climbed about 3 percent on Wednesday.
"It's not expensive" around $44 per share, he noted, saying that it could make a good long play into the summer.
