I’ve got a couple quick personal portfolio updates to share with you today, including an add-on warrant buy, but first I thought you might enjoy a quick look at a teaser ad for one of Thomas Garrity’s picks from Cabot Small-Cap Confidential — they’re promoting this pretty actively right now as a “$20 biotech stock to hit $48,” as their innovative medical device gets approval to treat a much larger number of patients.

So what is it?

Spoiler alert: the stock turns out to be CSII — but let’s look into it Gumshoe-style … here’s the tease:

“$20 Biotech Stock to Hit $48

“What makes me say so?

“Because this company’s treatment for Peripheral Arterial Disease (PAD), which will affect one in 20 Americans in their lifetime, could make heart angioplasty obsolete.”

OK, so that’s a nice big market — what’s the technology that’s shaking things up, and that has already driven the shares of this stock to more than double, with more (so they say) to come?

“Unlike angioplasty, which uses a metal mesh to inflate and stretch traumatized ...
