NEW YORK (TheStreet) -- The S&P 500 slid 0.28% Tuesday but the bigger news centered around the first confirmed diagnosis of Ebola in the United States. 

On CNBC's "Fast Money" TV show, the trading panel took a look at companies such as Sarepta Therapeutics (SRPT) - Get Report  and Tekmira Pharmaceuticals (TKMR) , which could have treatments for Ebola. 

Guy Adami, managing director of stockmonster.com, said shares of Tekmira seem poised to rise to $30 and can continue higher purely on investor sentiment. 

Brian Kelly, founder of Brian Kelly Capital, agreed with Adami, saying shares of Ebola-treating companies can move higher if investors think the companies' treatments will be in demand.  He added that a large portion of the global cocoa supply is from West Africa, meaning cocoa could become more expensive if there is a shortage. 

Karen Finerman, president of Metropolitan Capital Advisors, suggested that travel could decline if fears of Ebola reaches too high. The airlines could suffer as a result but a stock like Polycom (PLCM) , a video-conference company, could benefit. 

Steve Grasso, director of institutional sales at Stuart Frankel, said the S&P 500 seems poised to retest its 100-day moving average near 1,957 as well as its 200-day moving average near 1,900. 

Chris Garabedian, president and CEO of Sarepta Therapeutics, said there has not been a formal request asking for the company's current Ebola vaccines, of which there is currently only enough to treat a few dozen patients. In order to ramp that supply up to a few thousand treatments it would take a lot of money and time, possibly longer than one year, he said. However, these vaccines had a 60% to 80% survival rate when used on primates, whereas almost all of them died within eight to 12 days when left untreated. 

WTI crude oil slid over 3%, settling at $91.40 per barrel. Kelly argued the Russell 2000 should be doing better as gasoline prices continue to fall. He said this particular decline in oil likely didn't have much to do with the rising U.S. dollar. 

Grasso said crude oil seems likely to decline to $85 per barrel. Adami argued that WTI crude oil is declining due to deflationary issues. He added that the bond yields seem likely to decline, as does the S&P 500.

Kelly said he is long gold and gold mining companies. Adami added that it's not a bad idea for investors to keep some gold in their portfolio. 

Finerman said she remains long the S&P 500 and short the Russell 2000 because large-cap stocks continue to outperform small-cap stocks. 

eBay (EBAY) - Get Report announced it will spin off of its PayPal business. Adami said Apple's (AAPL) - Get Report Apple Pay probably influenced management's decision to make the move. Previously, eBay management did not want to separate PayPal from its core business operations. 

Jim Murren, chairman and CEO of MGMResorts (MGM) - Get Report , said it's good news that the investigation on corruption in Macau is winding down and may be over soon. However, the protests in Hong Kong will likely have a negative effect over the short term on Macau. He said the company reported good earnings in the last fiscal quarter and is off to a good start this fiscal quarter, too. 

Grasso said investors who want more exposure to Las Vegas can buy MGM Resorts, but those who want more exposure to Macau should buy Las Vegas Sands (LVS) - Get Report . Kelly said that there is a lot of bad news already priced into casino stocks with exposure to Macau and investors can likely get involved on the long side. 

Paul Hickey, co-founder of Bespoke Investment Group, was a guest on the show. Although October is typically considered a poor month for stocks, he said the three best-performing stocks include Reynolds American (RAI) , Ryder System (R) - Get Report and Google (GOOGL) - Get Report , with Google averaging a 14% gain in the month of October over the past 10 years. 

Adami said the iShares Russell 2000 ETF (IWM) - Get Report still seems poised to decline to $108. The S&P 500 continues to find support near 1,970 but may see a pullback to 1,904. 

For their final trades, Grasso said to buy KH Home (KBH) - Get Report , Finerman was buying Finish Line (FINL) and Adami and Kelly were buyers of the iShares 20+ Year Treasury Bond ETF (TLT) - Get Report .
