Verdict: the second week did not confirm the first. The builders bounced back over the line they had broken; the users held their floor but did not make a new record. The month still belongs to the users — the week did not.

Last Sunday this Signal read the first week of the funds' new year as a choice for the companies that use AI over the companies that build it, and named the lines that would confirm or deny it by Friday. The build-out index rose 8.2% and closed back above 1,559.55 — the line that would say the first week was only a week. AI Users rose 0.3% and stayed under its record. The applications index held its 905 floor, and the Nasdaq 100 fund stayed far above 636.
