From the speaker
- this year
- NVidia
- 23.4%
- the S&P
- 11.5%
- down significantly more
Our interpretation
- Read this as calendar-2025 price changes through the latest market quote available when the post was published on April 10.
- Read S&P as the S&P 500 price index. Measure both changes from the final closing prices of 2024, excluding dividends.
- Significantly means materially larger, not statistical significance.
- The quoted percentages should round to the stated tenths at a common cutoff. The post supplies no quote timestamp.
- This concerns securities-market returns, rather than NVIDIA's corporate finances; metric_scope is null.
Counts as supported if: Comparable market records at the publication-time cutoff show NVIDIA down 23.4% and the S&P 500 down 11.5%, rounded to one decimal place.
Counts as contradicted if: Comparable records at the relevant cutoff establish materially different percentages or show that NVIDIA had not declined substantially more.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Was it true for the period described?
Outcome: Unresolved
The record was checked, and the evidence available by the cutoff does not settle it.
Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale
The located reports give NVIDIA down 21% at an intraday snapshot and the S&P 500 down 10.4% at the close. Neither verifies the quoted pair at publication. Different intraday cutoffs could explain the discrepancies, so these reports do not justify calling the precise claim false.
Limitations
- Primary historical records sought were inaccessible or returned the wrong period.
- The exact percentages remain unverified; the reports are context rather than decisive evidence.
Evidence (2 items)
Context only: Associated Press, syndicated by The Epoch Times,
The S&P 500 is down 613.58 points, or 10.4 percent.
Why it matters here: The closing year-to-date decline differs from Marcus's figure. It cannot contradict an unspecified earlier intraday quote. Accessible primary records were not obtained.

Why it matters here: The article describes trading around 1 p.m. ET and reports a different NVIDIA decline. Without the post's cutoff, this snapshot cannot settle its precise percentage.

What would settle it
A timestamped source for Marcus's figures, or his publication-time cutoff together with matching historical NVIDIA and S&P 500 quotes and their final 2024 closing values.
