(Updates from10:12 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: Cramer said dry bulk shipper Diana Shipping ( DSX) is one way to play an uptick in world trade despite a recent analyst downgrade. He said Amazon.com ( AMZN) is an overvalued stock and keeps getting more overvalued every day. DSX ended Tuesday trading up 4.8% to $8.75 while AMZN rose 1% to $275.59. Cramer was bullish on JPMorgan Chase ( JPM), saying the bank is returning a lot of capital to shareholders, and also Chart Industries ( GTLS), a company that helps make liquified natural gas possible. JPM rose 1% to $49.49 and GTLS was up 5.7% to $81.95. Also in the plus camp was Papa John's ( PZZA), with Cramer saying the company's minor restatement of its financials is likely not a big deal. He said Ascena Retail Group ( ASNA) is a company that had been disappointing but now has "suddenly gotten it right." PZZA was up 5.3% to $58.48 while ASNA rose 14.3% to $18.90.
