“and for expected inflation, is about 3200 by the end of 2023.”

Jeremy Grantham, GMO viewpoint author January 2023 After a Timeout, Back to the Meat Grinder! (GMO)

Prediction Economics and markets

The inflation-adjusted trendline value of the S&P 500 will be about 3200 by the end of 2023.

Unresolvable The public record could not settle it.

Prediction: Statements about events outside the person's control, checked once they fell due: did they come true?

The second judge would not resolve this claim; the verdict shown is the first judge's.

Said for an organisation they lead or work for; it counts on both records.

What would count as true or false

Judge at end-2023. Use the S&P 500 inflation-adjusted trendline value that GMO or Grantham stated for end-2023 in later publications, or one recomputed on GMO's stated method using realised inflation. 'About 3200' allows roughly ±5% (about 3040–3360). True: the trendline value for end-2023 falls within that band. Mostly true: it falls within ±10% (about 2880–3520). Mostly false: it falls within ±15%. False: it is more than 15% away from 3200. The actual S&P 500 price level is not the test; the trendline value is.

Evidence (4)

  1. E1 You don’t need to forecast to be a successful investor. Roger Montgomery (rogermontgomery.com) · 14 March 2024

    “3200 would be a decline of just 16.7 per cent for 2023 and with 4 per cent inflation assumed for the year would total a 20 per cent real decline for 2023”
  2. E2 Wall Street Veteran Who Predicted The 2000 Tech Bubble, 2008 Subprime Crisis, Doubts Fed's Ability To Sidestep Looming Recession Benzinga · 18 August 2023

    “The expert forecasted that the S&P 500’s trendline value would hover around 3,200 by year-end, standing over 1,000 points lower than its present level.”
  3. E3 Newsletter Volume 16, No. 1 February 2023 Advisor Perspectives · 7 March 2023

    “And from Jeremy Grantham (1/26), “Most of the superbubbles go below trend and stay there for quite a while. This time, the trend is at most 2,500.”
  4. E4 Consumer Price Index News Release U.S. Bureau of Labor Statistics · 12 January 2024

    “Over the last 12 months, the all items index increased 3.4 percent before seasonal”

Reasoning

The evidence restates the forecast of about 3,200 [E3] and gives realised 2023 inflation [E5], but no item gives an end-2023 trendline value stated later by GMO or Grantham, or one recomputed on GMO's stated method. E2's 4% figure is not shown to be the trendline's inflation input, and E4 quotes Grantham giving a different trend figure of at most 2,500.
