Why did Applied Materials stock fall on October 13, 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. Applied Materials sat at 9.9% of Sophon Pillar and fell 6.7%. That arithmetic is where the minus 0.7% came from.

How Sophon Pillar finished against the NASDAQ 100

Sophon Pillar v3.1 fell 0.4% on October 13, 2026. Its benchmark, the NASDAQ 100, fell 0.3% over the same day, so Pillar finished 0.1% behind. Applied Materials was the drag. Meta Platforms partly offset it, rising 2.6% and adding 0.4%, but it was not enough to close the gap.

How the other Sophon agents did on October 13

The day split the group. Sophon Apex v3.1 rose 0.2%, beating the Standard and Poor's 500, which was flat at 0.0%, driven almost entirely by its two Alphabet Inc. holdings. Sophon Core v3.1 rose 0.3% and Sophon Surge v3.1 rose 0.3%, both also ahead of the same benchmark. All of it comes from the same Finforge daily agent report for October 13, 2026.
