On his 1,000th "Mad Money" episode on Wednesday, Jim Cramer said that investing "isn't always about common sense." His case in point was Emerson Electric ( EMR), which cut earnings forecasts and whose CEO doesn't expect things to improve much until 2011 at the earliest. The stock, however, traded almost flat on Wednesday.Cramer called it a bottom and said that with all the bad news on the table and company's 6% yield, Emerson's a buy. On Thursday, Emerson closed up 5.9%, or $1.79, at $32. Cramer spoke with NYSE Euronext ( NYX) Duncan Niederauer, who said the company's dividend is safe. Cramer said he liked both Niederauer and NYSE Euronext. NYSE Euronext closed up $1.68, or 8.5%, at $21.51 on Thursday. In his "Lightning Round" segment, Cramer said that Quanta Services ( PWR) is a "good, solid stock" and said it should go to $23. He recommended sticking with it. Quanta added 44 cents, or 2%, to close at $21.99. He said that for solar stocks such as First Solar ( FSLR) to make money, oil needs to be at $80 to $90. He called First Solar "stagnant." First Solar closed up $6.36, or 4.7%, at $142.05. Cramer said he missed the boat on J.Crew Group ( JCG) and that it's now "up huge," but nevertheless, he said the stock's OK at $12. J.Crew added 11.2%, or $1.64, at $16.25. Shire Pharmaceuticals ( SHPGY) has a "great basket of drugs," and Cramer thinks it should work as a play on coming out of the recession. On Thursday, Shire lost a penny to close at $36.30.
