Evidence: the owner-earnings backtest in full

The claim. If you had bought the fifth of companies with the highest ten-year owner-earnings return each year from 2011 to 2025, held a year, and repeated, you would have beaten the S&P 500 by +0.4 pts a year on average (indistinguishable from luck), and beaten the bottom fifth by +1.4 pts. Over three years the gap was −1.6 pts a year. Measured on 13,036 company-years, prices taken the first close after each annual report.

Every table behind the equity-bond ranking: quintiles, growth types, sectors and years, with the method and its limits.

How we tested it
  • Universe: 2,125 U.S. companies with ten-plus years of prices; banks, insurers and REITs excluded by SIC (no owner-earnings coupon).
  • Point in time: at each annual report's filing date we computed the coupon (three-year average of operating cash flow − capex − stock compensation, per diluted share), the yield at the next close, and a five-year revenue growth rate capped between −5% and +15%, using only filings available that day. Later restatements were never used earlier than they were filed.
  • Return: a ten-year internal rate of return with five years at that growth, fading to 2.5% by year ten, sold at fifteen times year-ten owner earnings. Companies ranked into fifths within each filing year.
  • Outcome: total return over the next twelve and thirty-six months minus the S&P 500, using split- and dividend-adjusted prices.
  • Limits: the universe is survivorship-tilted and small-cap, so the levels run negative; the spread between rows is the finding. No costs deducted.

What buying by owner-earnings return actually did

Point-in-time test on 2125 U.S. companies, 13,036 company-years: at each annual report's filing date we computed the coupon (three-year average owner earnings), the yield at the next close and a capped growth rate from the filings available that day, ranked every company by its 10-year IRR within that year, and measured the next 12 and 36 months against the S&P 500. Same definitions as the table above. Hypothetical, before costs; history, not a forecast.

10-yr IRR quintile (ranked within each year)Company-yearsAvg 12-mo excess vs S&PMedian% beat S&Pt-statAvg excess, next 3 yrs (per yr)
Q1 lowest2,614−1.0%−8.0%40%-0.52−16.5%

Q42,607−0.5%−5.2%43%-0.52−11.9%
Q5 highest2,601+0.4%−7.5%42%0.35−18.1%

Levels are negative in most rows because this universe (companies with ten-plus years of prices, many of them small) trailed the S&P over the period; the spread between the top and bottom rows — +1.4% points over 12 months, −1.6% a year over three — is the finding.

Growers vs steady compounders — does the lens sort both?

Buying the top fifth within each sector

The same rule applied sector by sector (SEC industry groups; sectors with fewer than 150 company-years are omitted). Where the top fifth does not beat the bottom fifth, the lens is not sorting that sector — read those rows as a warning, not a strategy.

Takeaway: Across 13,036 annual-report observations on 2125 companies (2011–2025), the top fifth by 10-year owner-earnings IRR beat the bottom fifth by +1.39 pts over the next 12 months versus the S&P 500 and by -1.56 pts a year over three years; the top fifth led in 7 of 15 years. Growers and steady compounders are ranked on the same scale: growers top-vs-bottom +1.6 pts, moderates top-vs-bottom +2.1 pts, steadys top-vs-bottom +3.7 pts. Universe: every 10-K filer in the SEC financial statement data sets with FirstRate prices, including companies later delisted (a failed company counts as a total loss), so the ranking is free of survivorship bias.

Generated 2026-09-14. Point-in-time SEC companyfacts (as filed); coupon = 3-yr avg (OCF − capex − SBC) ÷ diluted shares; g = 5-yr revenue CAGR floored −5% / capped 15%; IRR = 10-yr with 5-yr growth then linear fade to 2.5%, 15× exit; price = first raw close on/after the 10-K filing date; outcome = total return minus SPY (adjusted closes) over 12 and 36 months; quintiles ranked within filing year. Survivorship: only companies with a continuous price history qualify, which flatters every bucket about equally; treat the differences between rows as the finding, not the levels. Banks, insurers and REITs excluded by SIC, as on the table above.
