There are three macroeconomic themes that are continuing to support U.S. stock rally right now, Kabra said. First is the "reshoring boom," which has encouraged more domestic production and led to a "re-industrialization" of the US. Then there's the AI boom, without which the S&P 500 would be at around 4,400, he said. And more recently, Societe Generale is optimistic about US financials as credit conditions and lending standards improve.
