Over time

The earnings growth the price-to-earnings ratio requires, against the growth our model assumes. Net income is already after interest, so it is valued at the return shareholders require, plus spare cash (none for banks and insurers, whose cash is funded by deposits and policies), with no debt subtracted.

StrategyS&P 500, buy and hold Hypothetical, before costs. The strategy holds the S&P 500 and only changes on a signal: it switches into AMG in long quarters and adds a short of AMG in short quarters. The gap between the lines is what the signal added or lost.

Skill or luck?

In plain English: Across 10 quarters with a position, this lens beat the S&P 500 in 6, by −0.4% a quarter on average. That could easily be chance. One company is a small sample: the results across all companies are the better guide.

Each position is measured against the S&P 500 over the same quarter: a long earns the stock's return minus the index's, a short the index's minus the stock's. "A year" compounds the per-quarter results. Evidence: strong at a t-statistic of 2 or more, some from 1.5; "worse" when the result is that far below zero; one company's history is a small sample, so read these alongside the results across all companies.

Price paid: the closing price that day as traded, before any later share split.

How the test works

At each quarter end since March 2010 we rebuild the models from Affiliated Managers Group, Inc.'s quarters ending at least 90 days earlier (and no more than 200 days before that), using the figures as later filed, including any restatement, and value them at that day's close, adjusted for later share splits and spin-offs so that price and share count are on the same basis. A wide enough gap is a long or a short for one quarter (growth 10 points; margin and return on equity 5 points; a PEG under 0.75 or over 3), measured on total return against the S&P 500. The rules were set before the test. No trading or borrowing costs; today's list of companies. Not investment advice. All companies and the results across them.
