We recorded 10 claims from this post. See every claim from this post.
The wording above is the version this site observed on 2026-10-28. The source may have been edited after 2026-06-25. This page does not claim the wording was captured then.
What the claim commits to
- Kind
- Observation
- Deadline, as the speaker wrote it
- None stated. This site does not add one.
- Deadline state when assessed
- No horizon
- Deadline state on 2026-10-29
- No horizon (the release’s reference date)
Conditions
- most of them (scope, stated by the speaker)
- for the month (qualifier, stated by the speaker)
From the speaker
- most of them
- down significantly
- for the month
Our interpretation
- 'Them' refers to the same fixed stock set shown in the post's charts; 'most' means more than half.
- The plain reading of 'significantly' is a substantial investment loss, not statistical significance or any negative return.
- The provisional reading of 'for the month' is June month-to-date through the June 25 observation. A chart explicitly showing a trailing one-month interval would establish a different intended window.
- No numerical significance threshold is imposed without disclosure; a borderline result must remain unresolved.
Counts as supported if: A majority of the identified stocks show clearly substantial price declines over the intended month window through the post's observation time.
Counts as contradicted if: A majority are flat or higher, or the losses cannot reasonably be described as substantial for a majority of the identified set.
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 reporting establishes a substantial June decline for Microsoft, but one company cannot establish a majority of an unidentified basket. The missing chart also prevents a reliable choice between June month-to-date and a trailing month. The available evidence therefore does not settle the claim.
Limitations
- The month-to-date window is provisional.
- A numerical threshold for 'significantly' could determine a borderline result.
- The cited news report is contextual rather than a complete market-data reconstruction.
Evidence (1 item)
Context only: MarketWatch / Dow Jones, syndicated by Tiger Brokers,
Shares of Microsoft are down more than 21%
Why it matters here: The article's original timestamp is June 25 at 16:51 ET, although the host displays June 26 locally. It documents a substantial month-to-date decline for Microsoft, but membership in Marcus's basket and the basket-wide result remain unverified.

What would settle it
Recover the chart constituents, interval and timestamp, then calculate consistent returns for every constituent. If the majority consists only of small declines, clarification of 'significantly' would still be needed.
