PORTFOLIO IDEAS CLOSED IN MAY
Kronos Bio (KRON) -24% in 5 Months
Kronos Bio was a busted biotech trading at a steep discount to net cash after scrapping its lead clinical trial. The company launched a strategic review, laid off 83% of staff, and the CEO resigned—getting a $900k change-in-control bonus on the way out. Insiders, including the former CEO, owned over 27% of the stock. It seemed like the strategic review was likely to result in a positive outcome for shareholders. Assuming it would take several more months to complete, upside to forward NAV was 48%. Instead, this month KRON was acquired by Concentra Biosciences for $0.57/share in cash, plus a CVR tied to post-closing net cash above $40m and future asset recoveries. Initially, the CVR looked pretty interesting, however, the later released proxy showed underwhelming value assumptions from the management, undercutting the appeal.
Microstrategy (MSTR) – very big mistake
MSTR was trading at a wild 100%+ premium to NAV (almost entirely made of its Bitcoin holdings). Historically, these premiums didn’t last. Past surges to 140%+ had always repeatedly reverted to more “reasonable” 30–50% levels. So, this looked like a compelling bet on premium normalization. As Mark Twain said, history doesn’t repeat itself, but it often rhymes. The setup also allowed for a clean hedge via Bitcoin spot ETFs.
However, the premium didn’t normalize. It held, and the bubble still looks far from popping. In fact, we now have a growing cohort of (smaller) crypto treasury stocks trading at absurd NAV multiples. MSTR continues to issue stock at over 100% premium to NAV—seemingly without friction. I was wrong to think Bitcoin ETFs would curb demand for a stock trading at 2x its NAV. I also underestimated how much MSTR’s NAV would grow because of that very issuance. Both were big mistakes that resulted in large losses. Time to move on.
