Dylan Ratigan hosted CNBC's "Fast Money" show Friday night. He kicked off the show with a discussion of how the credit markets acted a little bit better today. Noted valued investor Karen Finerman explained that it's very hard to find values in a market like this, because valuations change within hours. She says "valuations we're seeing right now are extraordinary if you have a longer-term outlook."Pete Najarian said, "The market made an amazing run higher even with volatility at new highs." He told viewers to look for some value plays even if you have to reduce the earnings yourself. Ratigan brought up comments Warren Buffett made in his op-ed in the New York Times today. Buffett was quoted as saying "even in the Depression, stocks bottomed in the 1930s very early in that decade, even as the economy continued to deteriorate for years." Ratigan asked the traders if now is the time to buy assets. Terranvoa said yes, and he likes names such as General Mills ( GIS), MasterCard ( MA), Potash ( POT) and National-Oilwell Varco ( NOV). Karabell pointed out the action in Schlumberger ( SLB) today shows that investors are trading purely on "emotional news." Najarian mentioned that Halliburton ( HAL), Nabors ( NBR) and Weatherford ( WFT) all report earnings next week. He says "an amazing amount of options traded on the United States Natural Gas Fund ( UNG)." The "Chart of the Day" was the Baltic Exchange Dry Index, which has made a huge drop and is now down 63% on the year. Karabell says "This index isn't a good indicator of what's going on in a macro way." Najarian said to take a look at Peabody Energy ( BTU) because its numbers were outstanding. He also likes Union Pacific ( UNP) at $55 per share and Burlington Northern Santa Fe ( BNI) at $75 per share.
