Mike Flaum Says MSTR Will Rip 'Massively' Next Bull Run. He's Probably Right.

Mike Flaum isn't hedging. The Log Scale CEO says Strategy's stock will perform "massively" to the upside the next time bitcoin really runs. He's probably right. And most people are modeling this thing wrong.

Here's the setup. Strategy, the company formerly known as MicroStrategy, sits on more than 640,000 bitcoin. That's a lever. Not a metaphor, an actual lever. Every 10% move in BTC gets amplified through the equity, the converts, and now a growing stack of perpetual preferreds.

This changes things for anyone who wrote off MSTR as just a high-beta bitcoin proxy with a Michael Saylor problem.

The Stretch Play

Flaum walked through the product stack in his interview this week. There's Strategy's Stretch, a structure built to let the company keep stacking bitcoin without handing common shareholders a fresh dilution notice every quarter. Then there's the preferred complex. STRF at a 10% coupon. STRK at 8%. STRD at 10%. Daily dividends. Cash hitting accounts every single day.

That last part is the pitch he's making to retirees. Why hold a 10-year Treasury near 4% when a bitcoin-backed preferred pays roughly double? It reframes the whole product from a degenerate trading vehicle into an income instrument. That's a real narrative shift, and it's aimed squarely at the $6 trillion sitting in boomer retirement accounts.

Flaum's sharper point is the one about volatility versus risk. He wants you to stop treating them like the same thing. Is a 60% drawdown real risk if the underlying asset keeps compounding for a decade? Or is it just the price of admission?

I think he's onto something. Most people can't separate a scary chart from a broken thesis.

Where the Bear Case Lives

Now steelman the other side, because it isn't weak.

MSTR's premium to net asset value is the whole ballgame. If bitcoin rips 100% and the mNAV compresses from, say, 2x to 1.2x, the stock can badly lag the coin it holds. The lever cuts both directions. Plenty of investors learned that the hard way in 2022.

And the preferred stack isn't free money. Those dividends are obligations. If bitcoin chops sideways for 18 months, Strategy keeps paying out hundreds of millions a year while the ATM machine slows to a crawl. Daily dividends feel incredible in a bull market. They're a treadmill in a flat one.

Refinancing is the other soft spot. Converts mature. Rates move. The capital-markets window that's wide open today can slam shut in a week.

So the bear case isn't "Strategy is fake." It's "you're paying too much for the exposure." That's a much harder argument to dismiss.

The Verdict

I'll take Flaum's side, with one condition.

The convexity is real. Strategy is the only public vehicle with this much bitcoin and this much capital-markets machinery behind it. When the next bull run comes, the equity will rip harder than spot. "Massively" isn't hype, it's arithmetic.

But the premium decides how much of that upside you actually keep. Buy MSTR at a bloated mNAV and you're paying for somebody else's gains.

The market's verdict: the trade works. It just works a lot better for people who watch the premium as closely as they watch the price.

Watch the next filing. Any new size in the preferred stack, any shift in average cost basis, any commentary on the mNAV. That's your tell. And if bitcoin breaks out while the premium stays fat, Flaum gets the last laugh.
