The main reason I’ve bought equities again
The article is behind the Financial Times paywall so full text is unavailable. From the headline (“The main reason I’ve bought equities again”) it appears to be an opinion piece explaining why the author has returned to equity exposure. That suggests a bullish personal view toward US equities (represented here by the US SP 500). Without access to the article’s arguments, data or timing, market impact cannot be assessed beyond that it likely reflects a positive sentiment toward stocks and could be used as anecdotal support for bullish investor sentiment on the US SP 500.
