Investigating Casey's Cobalt "Biggest Gain in Penny Stock History" tease -- Stock Gumshoe Daily Update

Million-dollar bets, pot stocks, Chinese MSCI buys, and smart metal... miss anything last week?

The most widely-requested teaser solution of the week came late this time, on Thursday, when Michael Robinson started talking up the idea of a "shape shifting metal" that would make silicon obsolete (and somehow generate 4,000% gains) ... what was that story all about? Click here for my take.

But that wasn't all ... the week started with my look at the Motley Fool's "Million-dollar bet" -- a stock they say they've recommended several times and is still a hot buy for new money now... what is it? Thinkolator results here.

Then it was the "two stocks every Wall Street firm will be forced to buy on May 31" pitched by Steve Sjuggerud -- that's all about the inclusion of more Chinese stocks in the MSCI indexes,my story is here.

Then it was time for another look at Ray Blanco's "Secret $50 Pot Stock Blueprint" strategy, pitching a few of his favorite marijuana investments... that story is here.

And the wild and wooly week came to a close, with some updates and thoughts and a couple portfolio changes to note for the Irregulars this week in your Friday File -- including a new speculation, an add-on buy, and some thoughts about a couple of my dividend growth stocks. Our dearest friends can find that here.
