Why macro theses fail: confirmation, positioning and regime change
A thesis can describe the economy correctly and still fail as a market call. Accountability requires separating those outcomes.
The mechanism was wrong
Correlation is often promoted into causation. A thesis may omit a balancing response, confuse a stock with a flow or assume a stable relationship where institutions changed. Writing the transmission chain exposes the weakest link before the market does.
The timing was wrong
Macro lags are variable. Being “early” can become an unfalsifiable excuse unless a horizon was registered. State when the evidence should appear and define a review date. If the mechanism is intact but timing changes, preserve that revision publicly.
The view was already priced
A valid fundamental thesis may be consensus and fully reflected in valuation or positioning. Track market confirmation, expectations and crowding separately from the economic evidence. Surprises move prices; correct levels alone may not.
The data changed
Initial releases are noisy and revised. Backtests using final data can create signals that were unavailable in real time. Use vintages where possible, store release and revision dates, and mark analyses that rely on revised history.
The analyst moved the goalposts
One-sided evidence, silent edits and post-hoc thresholds protect the analyst at the user’s expense. Preserve versions, display contradictory evidence and keep invalidated themes in a graveyard. The objective is not a perfect hit rate; it is prompt, visible updating when the balance of evidence changes.
