Jim Cramer's Mad Money In-depth Stock Picks 4/20

Stocks discussed on Cramer's Mad Money TV program, Thursday April 20th. Click on a stock ticker for more analysis:

Scientific Games Corp (SGMS) -- Spain's Catalonia recently hired SGMS to run its instant lottery, which are 'predators of the poor' and 'reverse Robin Hoods' but very profitable; added to the S&P 400 today -- when this happens, stocks usually see a sustainable, long term rise

Emcore Corporation (EMKR) -- Though Wall St. doesn't like complex and 'confusing' companies, this one has legs in four money making businesses: optical deals with Cisco Systems (CSCO), solar panels, cell phones, and next-gen lighting business with General Electric (GE), which is the most promising. The 'potential holy grail stock for the next couple of years'.

Freescale Semiconductor Inc. (NYSE:FSL.B) -- Jumped up recently after reporting blowout quarter, but Cramer says we can still expect 'some serious Wall St. affection' for it; Motorola Inc. (MOT) spun it off recently, and hasn't moved much; Freescale has most of MOT's business and is growing share there; also has high-growth automotive unit.
