Buy Buy Drugmakers When a Major Drug Trial Finishes · ClinicalTrials.gov events
Drug companies register their trials with the government, and the record shows when a late-stage (Phase 2 or 3) trial is finished. Results usually come out within a few weeks. This buys the company for three months when a trial is marked complete, but only once per company every three months, since big drugmakers finish trials most weeks. Past tests showed a small gain on average; the record decides.

The planned holding period in these tests is 3 months (90 days), from opening to closing an idea.
At the next trading day’s close after the record posts — the first price anyone could have had.
The same hold for every idea — no stop, no target — so nothing flatters the numbers.
At the next available trading close on or after the end of the hold, whatever the price.
Every number on this page uses this sell rule — the other sell rules we tested are under “The full test results and the math” below.
Research only — not yet confirmed by new trades
Not passed yet — 5 of 16 checks:
Passed — the other 11: Current calculation · Public disclosure dates · Complete finished trades · Every trade compared · Every trade priced · Enough separate trading days · Survives without the best three stocks · Survives higher costs · Rule frozen before the test · Rules tried alongside it counted · First new signals set aside.
Tested exit: 3-month hold. Historical results alone do not approve a rule for publication. New event tests include an estimated 0.20 percentage point round-trip trading cost, with a 0.50-point stress check.
New trades so far: 0 finished, across — separate days after the rule was frozen.
2 signals set aside across 2 disclosure days; 2 still need complete results. Missing results stay in the count.
Left: did worse · right: did better. Zero matches the comparison. pp = percentage points; the scale adjusts to include the result.
62 tries finished the 3-month test · 17 still open · 90 signals ever
Past results don't predict future ones.
Similar stocks means the index fund for each idea's sector — or the S&P 500 when we can't place its sector. (The S&P 500 for 4 of 62 tries here.)
| How it did against similar stocks | 2.5 percentage points better than similar stocks — over 3 months |
|---|---|
| Range for the average (95%) | −1.4 pp to +6.6 pp vs similar stocks — the range the average probably falls in, not a best-to-worst case |
| Tested on enough tries? | 62 tries on 54 separate days ✓ enough |
| Works in different markets? | More than all of the edge came from a single year (149%) — the rest took some back ⚠ one year did most of it |
| Spread across many stocks? | 36% from a single stock ⚠ leans on one stock |
| Still works without its biggest winner? | +1.6 pp vs similar stocks without MRNA ✓ holds up |
