If only I could get to every intriguing idea I hear...

With my relaunch, I’m restarting the Red Flag Radar, which lets you know what I’m seeing, hearing and even working on. I go out of my way trying not to cross that fine line between adding value and becoming noise. In the process, too many good ideas and tidbits get left behind. Like UPS $UPS, which I started looking at a few weeks ago for the second time in four years – this time before its recent 20% tumble on earnings. The story is almost identical to Carrier $CARR, which hit a screen that David Trainer of New Constructs created for me... in an effort to spot idiosyncratic situations with high risk. Carrier stuck out like a sore thumb, in part because his system had rated it as “unattractive.”

So, here’s the plan. In addition to what I currently do, including the bigger reports...

  • Expect more of “what I’m seeing, hearing and working on” via the Red Flag Radar, which already sees more than I let on. This is a work in progress.

  • Also, David and I are creating a monthly “Most Dangerous Stocks” list based on quant data from New Constructs, which eliminates fake earnings to give a true picture of how a company is really doing relative to its valuation. (That’s the simple explanation.)

  • At the same time, I’m creating an inverse short-squeeze list with data from the folks at All Star Charts, whose “freshly squeezed” list of likely short squeezes predicted the stratospheric squeezes of a few of my red-flagged names. (Not a fan of squeezes, here – especially companies I flag – but that’s the real world.)

All of this will be exclusively for premium members.
