I don’t want to give you too much to read, since probably the most interesting reading this weekend will be Warren Buffett’s annual letter to shareholders (which should be posted here as part of Berkshire’s Annual Report, around 8am EST tomorrow), but I do have a quick teaser answer to share with you… and a couple earnings-related updates on some Real Money Portfolio stocks…

First, as I was lolling on vacation for a few days this week I got buckets of questions about Marin Katusa’s latest “Forever Royalties” pitch for his Katusa’s Resource Opportunities newsletter ($2,500, no refunds), so I should get you a quick answer… and as you might not be surprised to hear, it’s the same answer as I provided the last time Katusa pitched a royalty story.

“It’s publicly traded… but it’s not a conventional royalty stock.

“If you ran a stock screen for ‘royalty companies,’ you’d never find it.

“Basically, it’s a ‘backdoor’ way to collect royalty checks from this $80 billion industry.”

And it’s well-established enough to have the backing of some big names…

“The investment and management team behind this secret ‘toll-road’ opportunity – all of whom I know and have personally worked with – are the 1-percenters of natural resource companies.”

So what does this company do?
