After Nike (NKE) fell 3.8% following its earnings result, should investors instead buy Sketchers (SKX) ? No, according to TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, who was answering viewer questions from the floor of the New York Stock Exchange

Nike had a "very good quarter," Cramer said. And while he does think Sketchers has a "sensational" management team, there isn't as much clarity with the business like there is with Nike. Nike is doing fantastic in China and the Olympic Summer Games are approaching. 

Cramer turned his attention to a natural and organic food manufacturer, saying, "we like WhiteWave Foods (WWAV) very much for Action Alerts PLUS." The company had a good quarter, but has struggled expanding in China. Shares have been under a lot of pressure lately, but if it dips below $38, it's a buy, he reasoned. 

WhiteWave could also make for an ideal acquisition target by Kellogg's (K) or General Mills (GIS) , he added. 

Turning to technology, a viewer wanted to know if it was time to buy Applied Materials (AMAT) . "Applied Materials is a very inexpensive stock, but Lam Research (LRCX)  is the star," Cramer responded. 

Finally, when it comes to silver or gold, Cramer prefers the latter. Investors looking to gain exposure to the metal could do so via Randgold Resources (GOLD) , he said.

Cramer answers viewers' social media questions on Facebook  (FB)  and on Twitter (TWTR) .

At the time of publication, Cramer's Action Alerts PLUS had a long position in WWAV, as well as FB and TWTR.
