NEW YORK ( TheStreet) -- Markets opened lower Thursday but the S&P 500 was able to fight through and closed marginally higher during a busy earnings week.Amazon ( AMZN) was the big name reporting earnings after the close on Thursday. The company posted a surprise quarterly loss of 2 cents per share on lower-than-expected revenue. Steve Grasso said on CNBC's "Fast Money" TV show that although it bothers the bears, Amazon is still priced as a growth stock. While it can drop $20 or $30 per share rather quickly, it has always had a "buy the tip" type of price action. Guy Adami added that if the stock was valued on its earnings alone, it would be trading for $150. But as long as operating margins continue to improve, he think investors can continue to own it. He cited a pullback to roughly $280 would be a good place to buy. Josh Brown said that near $280 the stock would be a buy. He added that the earnings report wasn't very good, and certainly did not justify another leg higher without a pullback. Brian Kelly took the pullback side and the breakout side. He said if the stock was over $305 on Friday, he would look to buy the momentum. But should that fail, he will look to buy around $280 on the pullback. Another earnings mover was Expedia ( EXPE), down over 20% in the after-hours trading session after missing on top- and bottom-line estimates. Brown said the travel Web sites stocks are some of the biggest winners, and he doesn't understand why they trade at such high valuations. He cited intense competition and profit margin compression as reasons not to buy the deep dip. Kelly added investors are telling the market that it is an industrywide issue, rather than stock-specific issue, with stocks like Priceline.com ( PCLN) and Orbitz Worldwide ( OWW) also down in after-hours trading. Facebook ( FB) was Thursday's big winner, up nearly 30% on the back of a huge earnings beat on Wednesday. Kevin Landis, president of Firsthand Capital Management, said he continues to like the name. He cited strong mobile user growth and ad revenue as reasons for why the company still has plenty of upside left.
A name often mentioned with Facebook is Zynga ( ZNGA), which is trading lower despite beating top- and bottom-line estimates on Thursday. Brown said the only statistic that matters is Zynga's subscribers declined from 72 million to 39 million in the last 12 months. His stance remained bearish. Guest contributor John Rogers, founder of Ariel Investments, says he continues to remain bullish on the overall markets. He added that the mergers and acquisitions space was just getting started and that corporate management is finally getting comfortable spending money to acquire. Starbucks ( SBUX) reported earnings on Thursday, with the company beating on the top- and bottom-line and raising full-year guidance. Adami said the stock continues to perform well, but the time to be long was before the announcement. He would not recommend chasing after the earnings pop higher. Brown added that the stock deserves its high trading premium because there is no other company that can quite compete with Starbucks. F5 Networks ( FFIV) popped 7% higher on Thursday, and Adami said that he would be a buyer on a breakout over $90. With a recent low of $67, he said there's too much downside risk in the stock to go long without enough momentum. With an even bigger jump was Boston Scientific ( BSX), up 13% from strong earnings per share results on Thursday. Mike Khouw said the company isn't growing top-line results enough and that at 25 times earnings, it's a little too expensive. He is not a buyer. For their final trades, Adami says to buy Blackstone ( BX). Grasso says he is a buyer of Google ( GOOG), but using $875 as a stopping point. Brown is buying shares of Ford ( F) and Kelly is going long Mexico via the iShares MSCI Mexico ETF ( EWW). -- Written by Bret Kenwell in Petoskey, Mich.
