NEW YORK (TheStreet) -- The S&P 500 slid 0.31% but the trading panel on CNBC's "Fast Money" TV show was focused on oil.

Pete Najarian, co-founder of and, said investors are rotating out of energy stocks amid falling energy prices. Transport stocks such as Norfolk Southern (NSC) - Get Report , Canadian Pacific Railway (CP) - Get Report and Canadian National Railway (CNI) - Get Report  plus airline stocks are moving higher, he added. 

Tim Seymour, managing partner of Triogem Asset Management, said oil prices seem likely to continue moving lower and will be a negative for refinery stocks, such as Tesoro Corp. (TSO)

Dan Nathan, co-founder and editor of, reasoned that many major asset classes have experienced an uptick in volatility such as global equities, currencies and commodities. But the volatility has not yet returned to the U.S. stock market. 

Mitchell Pinheiro, senior vice president of equity research at Imperial Capital, discussed General Mills' (GIS) - Get Report takeover of Annie's (BNNY) for $46 per share.

He said Annie's has a "terrific brand" that has many different categories for its food. The natural food is appealing to the public and specifically to the millennial generation. Other brands such as WhiteWave Foods (WWAV) and Boulder Brands (BDBD) could be other takeover targets, but Annie's was the favorite pick in the space, he concluded. 

Karen Finerman, president of Metropolitan Capital Advisors, suggested Hain Celestial Group (HAIN) - Get Report could be both a takeout candidate and a potential acquirer. 

Seymour said General Mills looks interesting on the long side and he is long Pinnacle Foods (PF) .

Nathan said it's healthy for there to be M&A in a bull market as long as the deals do not take place with egregious valuations. 

Najarian suggested that Campbell Soup (CPB) - Get Report could be a potential acquirer in the future. He added that the energy sector seems the most likely to experience consolidation.

Seymour said General Motors' (GM) - Get Report self-driving car aimed to launch in 2017 is impressive technology but is unlikely to have much of a short-term effect on the stock

Najarian said he likes Tesla Motors (TSLA) - Get Report  but prefers to own it through options in order to limit his downside. He also likes Ford (F) - Get Report

Finerman said MobilEye (MBLY) could be a potential takeout target, given its advances in collision prevention and autonomous capabilities. 

Apple (AAPL) - Get Report will hire Marc Newson. Kia Makarechi, news editor at, said Newson as one of the most influential industrial designers of our generation. The move is not that surprising given Newson's connection to some of Apple's current employees and the talent the company has hired in the previous year. The company seems likely to launch some sort of smart watch in the next year and investors may get a teaser of what's to come during Tuesday's announcement. 

Najarian, who is bullish on Apple, said the company's continued effort to bring in impressive talent makes him more bullish on the stock. 

Nathan said investor sentiment appears to be souring for Amazon (AMZN) - Get Report , while the price action seems to be bearish. 

Finerman said Amazon's new Fire smartphone had very low expectations. Despite this, the company still seemed to come in below expectations after slashing the price of its smartphone to 99 cents. Seymour agreed with Finerman and Nathan. 

Najarian argued that Amazon's smartphone is so small in the grand scheme of things that it doesn't really affect the business. The stock is neither a buy or a sell based on the phone. 

CNBC's Kayla Tausche was a guest on the show, reporting on the Alibaba (BABA) roadshow, which began in New York City on Monday. Investors who attended have "never seen anything like it," she said. The company has such a global reach and so much growth that the valuation may be too low, especially given how high its margins are. Expectations continue to mount, hence shares of Yahoo! (YHOO) traded higher by 6%.

Najarian reasoned that Yahoo! is going to $50 per share. Seymour said investors seem concerned about what Yahoo! CEO Marissa Mayer will do with the Alibaba proceeds. 

Campbell Soupfell 3% and was the first stock on the show's "Pops & Drops" segment. Najarian said he would buy the stock on this pullback. 

Macy's (M) - Get Report dropped 2%. Finerman said she is long the stock and continues to like the company. 

GoPro (GPRO) - Get Report climbed 8%. Nathan said he does not find this stock attractive but said the stock moved higher following an analyst upgrade. 

Yingli Green Energy (YGE) popped 6%. Seymour said he would avoid this stock because the company has "serious balance sheet problems."

Brent Thill, managing director and a senior analyst at UBS, upgraded shares of FireEye (FEYE) - Get Report to buy from hold and assigned a price target of $40.  The cyber security landscape is robust, he said, and the company is a leader in its industry. Although the stock has been under immense pressure and will experience slowing revenue growth, it has upside because of its robust environment, he concluded. 

Nathan said the stock seems overvalued, given how small FireEye's sales are compared to its market cap. 

Nathan pointed out a bearish options trade in Apple ahead of Tuesday's event. Specifically, 25,000 Sept. 12th $90 put options were bought for $0.25, meaning that for the trade to break-even, the stock has to close at $89.75 by the end of this week. 

For their final trades, Finerman is a buyer MolinaHealthcare (MOH) - Get Report and Nathan is a seller of Amazon. Seymour is a buyer of Weibo (WB) - Get Report and Najarian likes Nike (NKE) - Get Report on the long side.
