“This does seem to make the odds of a major decline in the near future quite low (famous last words?).”

Prediction Economics and markets

Grantham said that, unless there were substantial unexpected negatives, this did seem to make the odds of a major market decline in the near future quite low, adding "famous last words?".

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

Treat a 'major decline' as a peak-to-trough fall of 20% or more in the S&P 500 (closing basis), and the 'near future' as the period from the statement in 2017 to 31 December 2017. True: no peak-to-trough decline of 10% or more in that period. Mostly true: a correction of 10% to just under 20%, but no 20% decline. False: an S&P 500 decline of 20% or more occurred in that period.

Reasoning

The evidence gives only a few selected S&P 500 closes for 2017 [E1][E2][E3][E5][E8]. They show a pullback of about 2.2% in August and a higher close at year end. Because the full daily series is not in the material, the evidence cannot show that no peak-to-trough decline of 10% or more happened in the period, and the criteria need that to settle the claim.
