(Updates from 10:47 a.m. ET with closing information.) NEW YORK ( TheStreet) -- Here's what Jim Cramer had to say on CNBC's "Squawk On The Street" Tuesday. Citigroup thinks FedEx ( FDX) will have a positive outlook. Cramer warned that "you're taking your life in your hands" by getting into this stock before the company reports earnings. "Let it come in," he advised. FDX closed up 1.1% at $99.48. Red Hat ( RHT) has been getting crushed but Piper Jaffray thinks the stock is at a good price level. Cramer does, too, saying, "It's going to bottom soon." RHT jumped 2.1% to $46.63. Goldman Sachs added Enbridge ( ENB) to its conviction buy list. Cramer said the group has been horrendous but Goldman may be calling a bottom. ENB was 1.3% higher at $44.78. ConocoPhillips ( COP) was downgraded by Howard Weil. Cramer said this downgrade doesn't matter because "oil is going higher." COP was unchanged at $62.10. It's time to buy LinkedIn ( LNKD), according to Pacific Crest. Cramer said that with more investors wanting to buy and so few shares available there's "scarcity value" on this stock. LNKD was up 1% to $179.42. Wedbush likes Intuitive Surgical's ( ISRG) growth prospects. Cramer isn't as sure, citing CNBC colleague Herb Greenberg's recent study of the stock. ISRG ended Tuesday up 2.1% to $509.61.
