Do shares return less in the month after a regular payout cut than in the same company's ordinary payout months?

Study 24 · Inconclusive · recorded 1 October 2026 · answer: Not settled · full paper with figures

The question

We compare returns net of the market over the 21 trading days after a cut takes effect with the same company's months after an unchanged payout, so the company and its payout timing are held fixed. An earlier count, study twenty, found enough such cuts in our records to study.

Rules fixed before the result

Before any return was computed we fixed the rule for a cut, the 21-day window and the comparison, and required at least 100 cuts on at least 60 companies, with 20 in each of three periods. The month after a cut counted as weaker if the median difference fell below the lowest 2.5% of medians from 20,000 relabellings of each company's months, stronger if above the highest 2.5%, and otherwise not separated. Nine side checks were set, none deciding.

Data and method

A cut is a regular quarterly payment at least 2% below the previous one, by a company that had paid on a steady quarterly schedule for at least eight quarters. For each cut we took the return net of the market over the 21 trading days after it took effect, minus the average of the same company's months after an unchanged payout. The measure is the median of those differences.

The answer

Across 185 cuts by 89 companies, the median return net of the market was 0.88 percentage points lower than in the same company's ordinary months. Relabelling each company's own months at random put the middle 95% of medians between 1.26 points lower and 1.52 points higher, and the observed median lay inside that range, so the month after a cut is not distinguishable from ordinary months at this sample's size. Seven of the nine side checks gave the same reading; the other two, one using only each company's first cut and one leaving out 2020, had too few cuts to meet the minimums set in advance and could not be read. We expected this answer, at low confidence.

Main estimate

-0.009 fraction (95% range -0.013 to 0.015), from 185 observations

What it changes

Nothing changed. The answer opened or closed no line of work, and payout cuts were not carried to a planned study on this evidence alone.

What remains uncertain

We measured from the date a cut took effect, not its announcement weeks earlier, so much of any reaction may come before our window. Some ordinary months follow an earlier cut by the same company, the company's own months are the only comparison beyond the market, and cuts that cluster in the same stressed months are not independent. This is one sample of development years, and the returns rely on the price vendor's adjustment for the payout itself.

How it was made

Run took 18 minutes; independent code review: approve; the recorded calculation reruns to the same result.
