Looking into the "Magic Molecule" pitch from Green Chip -- Stock Gumshoe Daily Update

We started out last week with an updated look at those "Prime Profits" from Amazon that have been hyped up for years now, a way to get income from the e-commerce giant -- what's that all about? My updated story is here.

And it seemed half the week was Amazon-focused -- our next de-teasification was about an "Amazon Killer," a company making it easier for non-Amazonians to handle all the different state and local taxes... that one is here.

Then it was some little biotech stock that apparently Jeff Bezos has invested in -- this turned out to be one we've covered before, and a penny stock letter is touting August 7 as the key date for flowing riches... my take is here.

And Personal Finance is again teasing a way to get "extra benefits" of $1,569 a month -- and while that's technically possible, there's a bit of a catch. I explain here.

And for the Friday File, I put on a new short-term arbitrage position that our readers have already told me is foolish, as well as making a few extra buys this week despite my general trepidation about the markets and our current bubble-building conditions. Full details if you click below...
