Seymour said he would buy shares of Amazon (AMZN) near $250. Adami agreed.
Scaramucci said he was neither a buyer or a seller of Amazon and Netflix. He called the valuations "crazy."
Priceline.com (PCLN) is not an expensive stock in terms of valuation, Adami argued. He reasoned that the stock has been dragged lower over the past month during the selloff of momentum stocks.
Seymour agreed, calling Priceline.com "one of the great monopolies" and a "global franchise." Scaramucci said PCLN could rally if the overall market moves higher.
Twitter (TWTR) was the featured company on the show's "Street Fight" segment. Seymour was bullish on the stock over the short term, saying it has "relative value" at current levels. He added that it is cheaper than Facebook (FB) on a price-to-sales basis. He is long the June $32 call options.
Nathan was bearish on shares of Twitter, saying he expects the stock to eventually hit its IPO price of $26. He added that another share lockup expiration will transpire in roughly 90 days, which is likely to weigh on the stock price.
Adami said Twitter seems likely to rally at current levels.
Aswath Damadaran, professor of finance at NYU Stern School of Business, was a guest on the show. He valued Alibaba at $140 billion post-IPO, calling the e-commerce giant a "phenomenal money-maker." However, due to the company's lack of clarity about its investments, possible growth constraints and potential Chinese political strains, he was leery about putting a higher valuation on the company.
He added that if Alibaba can grow revenue at 40%, the stock should be worth between $180 billion to $200 billion. If it only grows revenue 25%, then the valuation should be closer to $120 billion. The valuation ultimately depends on two things: what revenue growth rates Alibaba can sustain, and how much the Chinese e-commerce market will grow over the next five years.
Seymour argued that even at a $145 billion valuation for Alibaba, shares of Yahoo! (YHOO) should still be trading near $40.
Dan Niles, founding partner of AlphaOne Capital, said he is a buyer of Google (GOOGL) and suggests the company will be better once it completely separates from its Motorola business. He is a seller of Microsoft (MSFT), saying the company may struggle with the handset business it acquired from Nokia (NOK).
