On Wednesday's "Mad Money" TV show, Jim Cramer interviewed Eldorado Gold (EGO) CEO Paul Wright. Cramer predicted a strong outlook for gold, and Wright said Eldorado is positioned for growth without having to depend on issuing more equity.Cramer encouraged viewers to make their own decisions regarding which gold stock to hold in their portfolios, but he said he likes Eldorado. He also recommended Agnico-Eagle Mines ( AEM) on a pullback, but he said that Northern Dynasty Minerals ( NAK) was too speculative. On Thursday, Eldorado closed down 16 cents, or 1.7%, at $9.10. Agnico-Eagle was down 42 cents at $57.75, and Northern Dynasty closed down 7 cents at $7.07. In his "Lightning Round" segment, Cramer called Coca-Cola ( KO) a buy based on its international exposure and its dividend. Coca-Cola closed up 10 cents at $44.85 on Thursday. He also liked PPG Industries ( PPG), which he said is "better quality" than DuPont ( DD) and Dow Chemical ( DOW). PPG closed up $1.83, or 5%, at $38.71 on Thursday; DuPont was up 62 cents, or 2.7%, to $23.48; and Dow Chemical closed up 57 cents, or 6.5%, at $9.37.
