Do shares fall behind the market in the month before a regular payout cut takes effect?
Study 54 · Inconclusive · recorded 14 October 2026 · answer: Not settled · full paper with figures
The question
A cut is usually announced in that month, which no earlier study of these cuts had measured. We compare each company's return against the market over the month with the same company's average over the same month before its ordinary, unchanged payments.
Rules fixed before the result
Fixed in advance: at least 100 cuts by 50 companies, 20 in each period and 500 ordinary months to measure the spread, and a comparison able to detect three percentage points over the month by the mean, or by the median if the mean could not; it could detect 2.94 points, so the mean decided. The median would also have decided had the mean's range been wider than 8.2 points; it was 6.0. No minimum or bar was changed.
Data and method
We took study thirty-six's 173 regular payout cuts by 85 established payers and, for each, summed the company's daily return less the market's over the twenty-one trading days before the first day the shares trade without the payment. From each we subtracted the same company's average over the same days before its ordinary, unchanged payments, and resampled whole companies 2,000 times for the ranges.
The answer
Not settled. Over the month before a regular payout cut took effect, the 173 cuts by 85 companies averaged 0.05% below the market beyond the companies' ordinary months (95% range 2.98% below to 3.02% above), and the typical cut 0.83% below (2.79% below to 0.88% above). The range excludes a fall of three percentage points, the size set in advance as the one that would matter, but just reaches a gain of that size, so the result is inconclusive; smaller moves either way remain compatible. The month before that averaged 1.08% below (3.42% below to 1.12% above), and the six weeks together 1.13% below (4.35% below to 2.23% above). Over the earlier six months the same companies had fallen behind by about 2.13% a month (1.39% to 3.08%).
Main estimate
-0.000 fraction (95% range -0.030 to 0.030), from 173 observations
What it changes
By the rule set beforehand, the payout question returns to a fresh verdict with this range; a fall concentrated in this month was expected, with low confidence, and was not found. Of ten checks set beforehand, three read level within three points: the raises, the typical cut and resampling by calendar month; the other seven were inconclusive. Cuts from 2017 to 2019 alone fell behind, and cuts from 2020 to 2022 alone pulled ahead.
What remains uncertain
These cuts were studied before: the month after they took effect in studies twenty-four and thirty-six, their earlier six months in study thirty-six, and their year before against comparable companies in study forty-three's check, but the month before had not been measured; the raises beside were studied in studies twenty-four, thirty-six, forty-three and forty-nine. Cuts by different companies in the same weeks share market news the ranges treat as independent, though resampling by calendar month gave a similar range.
How it was made
Run took 110 minutes; independent code review: approve; the recorded calculation reruns to the same result.
