Published research is overwhelmingly bullish on US equities right now, with the S&P 500, Nasdaq, Russell 2000, and tech and semiconductor names all drawing constructive views. The main dissent is a longer-term valuation and bubble warning.
The dominant thread across recent research is the AI capex supercycle: analysts point to AI-driven earnings momentum in mega-cap tech and chips as the engine behind record highs. Several note that passive and systematic inflows act as a structural floor, while easy financial conditions and the wealth effect provide near-term support. A separate camp argues the Russell 2000 is in the early innings of a multi-year outperformance cycle, citing improving small-cap earnings, below-average relative valuations, and tailwinds from tax policy, reshoring, and deregulation.
Semiconductors are the highest-conviction sub-theme, with NVIDIA the most-cited name. Some research flags chip forward earnings estimates up 100% since October, with memory names still on single-digit multiples. Defense and border-security names, plus small/mid-cap biotech tied to GLP-1 obesity drugs, also get structural buy cases.
The bearish counterweight: a contrarian thread argues AI revenues are circular and inference economics don't work, implying real cyclical downside, while another view flags US equities as overvalued on debt-to-GDP and market-cap-to-GDP. Upcoming SpaceX and OpenAI IPOs are also cited as a potential liquidity drain on listed tech.
