Caterpillar (CAT): buy, hold or sell?
Industrials. One systematic signal, updated after every US close, with the exact prices to act at.
CAT has a current end-of-day Hesper Atlas signal, refreshed after every US close. It is not real-time. The latest state and the full trade plan (exact buy / add / trim / sell prices) are in the app; a free account shows three full stock pages a day, no card required.
On the later 40% chronological validation tail, originally withheld from early tuning but reused in later research, the CAT engine returned +20.1% a year versus +18.1% buying and holding, with a worst drop of −62.9% versus −73.4% (after costs, next-day fills, 2026-07-07 evaluation).
What the engine did on CAT, honestly
Closed replay signals on CAT
No closed BUY-to-SELL round trips in the current-rule replay for this name yet. The full dataset is on the historical replay page.
Validation numbers: the engine is tuned on the earlier 60% of this name's history and scored on the later 40%, after costs with next-day fills. That tail was originally withheld but reused in later research, so it is not a pristine unseen test. Backtested, not live. Replay rows are BUY-to-SELL round trips regenerated nightly from end-of-day data; losers stay listed. Method on the methodology page; the row-level artifact is in validation JSON; every name’s current-rule replay slice is on the historical replay page. Hesper Atlas is an educational publication with one systematic signal per name, identical for everyone. It is not financial advice and does not know your situation.
