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.

Skill or luck?

In plain English: The gap has not been wide enough for a position in Klaviyo, Inc. since 2010, so there is no record to judge.

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.

How the test works

At each quarter end since March 2010 we rebuild the models from Klaviyo, 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.
