Why did Meta Platforms stock go up on October 12, 2026?

The report records the move and its effect, not the cause, and we will not invent one. What it shows is the mechanism. Contribution, the share of a day's return one holding produced, is roughly weight times move. Meta sat at 15.0% of Sophon Pillar and rose 3.4%. That arithmetic is where the plus 0.5% came from.
