6 months seems like a carefully cherry-picked number there, it is basically middle of the the trough of the tariff-induced market collapse that started 7 months ago and had been recovered from 5 months ago. That explains about 20 percentage points.
The USD is down about 10% this year. Anything USD-denominated needed to go up by 10% just to stay even in real terms.
So you're looking at a 30%-ish baseline for that specific 6 month interval. That's basically where Meta (etc) are. Of the larger outliers:
Nvidia continued growing at >50% YoY, and their largest customers announced increased capex spending plans.
Google's valuation had been depressed by uncertainty from ongoing anti-trust cases. One of them got resolved (and the day the remedies were announced is exactly when Google's share price decoupled from Microsoft, Amazon and Meta).
