NEW YORK (TheStreet) -- The broader market sold off sharply as Twitter (TWTR) - Get Twitter, Inc. Report made a successful public debut. 

On CNBC's "Fast Money" TV show, Dan Nathan, co-founder and editor of, said a lot of momentum names have been topping out and a pullback to 1,700 in the S&P 500 would be healthy.

Guy Adami, managing director of, said that 1,740 in the S&P 500 would be an important level for support. He added that the pullback in the Russell 2000 was worrisome, as well as the record level of margin debt at the New York Stock Exchange

Gordon Johnson, managing director of Axiom Capital Management, said the reaction in the stock market following the European Central Bank's decision to cut interest rates is definitely concerning and investors may have been a little too optimistic. 

Sam Hamadeh, CEO and founder of PrivCo, was a guest on the show who said Twitter was priced well and that it will grow into its valuation. As he did on Wednesday's show, he suggested investors wait for the second of the two lock-up periods to expire, on May 14, before buying a big position. He added that in April there might be some form of a follow-up offering, in which investors could consider buying.

Nathan said the stock has incredibly strong growth and is a solid buy in the low $30 range. 

Adami said the stock opened so high because demand is strong, while there is a very small supply of shares. He added that it had nothing to do with fundamentals. 

Disney (DIS) - Get Walt Disney Company Report reported solid earnings but traded lower. Adami called the stock a "no touch" until it returns to and holds $67, otherwise it may head to the low-$60s. 

Johnson said he preferred Chinese solar stocks over American solar stocks because the Chinese government is propping them. He would be buying on dips and added that he did not like SolarCity (SCTY)  due to potential accounting issues. 

As a trade, Jon Najarian, co-founder of and, said he would be a buyer of First Solar (FSLR) - Get First Solar, Inc. Report on weakness.

Tesla Motors (TSLA) - Get Tesla Inc Report had another harsh day of trading, down nearly 8% on news of a third car fire. Craig Irwin, an analyst at Wedbush Securities, was a guest on the show who said people need to consider the situations in which these fires are arising from and what would happen with a normal car. In terms of valuation, he said the stock doesn't trade based off metrics, but on strong growth and belief in its future potential. 

Johnson cited expensive valuation multiples and high battery costs as reasons for why he felt the stock was worth only $50. 

Nathan said traders should watch for support at $135 and $120 and argued that there's no way the stock was heading back to $50.

Alcoa (AA) - Get Alcoa Corp. Report was the first stock on the show's "Pops & Drops" segment and Adami said he would be a buyer at $8.75, with an upside target of $9.50.

Qualcomm (QCOM) - Get QUALCOMM Incorporated Report dropped 4% and Nathan said he would be a buyer near $65 ahead of the analyst meeting on Nov. 20. 

LTD Brands (LTD) fell 2%. Mike Khouw, managing director and primary strategist at DASH Financial, said its same-store sales guidance was a little low and the stock reaction is a potential warning sign to other high-multiple retailers. 

American Eagle Outfitters (AEO) - Get American Eagle Outfitters, Inc. Report jumped 4%. Najarian said this is one of the few companies doing well in teen retail. 

Transocean (RIG) - Get Transocean Ltd. Report popped 7%, and Gordon said he would be a buyer.

Groupon (GRPN) - Get Groupon, Inc. Report was higher after reporting earnings, and Najarian said he continues to like the stock and its push into mobile.

Nathan completely disagreed, saying the company is going to compete with Amazon (AMZN) - Get, Inc. Report and Costco Wholesale (COST) - Get Costco Wholesale Corporation Report, where it doesn't stand a chance. (PCLN) rallied after reporting earnings. Najarian said he continues to like the stock. 

Johnson said commodity stocks will likely rally from positive headlines out of the four-day Chinese government meeting that starts next week. 

Adami said he would avoid U.S. Steel (X) - Get United States Steel Corporation Report because it seems likely to trade down to $23.50. 

For their final trades, Najarian was a buyer of Community Health Systems (CYH) - Get Community Health Systems, Inc. Report, Johnson was buying Micron (MU) - Get Micron Technology, Inc. (MU) Report and Khouw said to short high-growth names via short call spreads. Nathan said to buy eBay (EBAY) - Get eBay Inc. Report with a stop at $50 and Adami was a buyer of WesternDigital (WDC) - Get Western Digital Corporation Report.
