BofA pours cold water: Don't count on the S&P 500 in 2027it's the world's most crowded trade

Wall Street analysts believe that in 2027, the S&P 500 may struggle to serve as the foundation for market longs. Savita Subramanian, head of U.S. equity and quantitative strategy at Bank of America, said on a program: "We are not particularly bullish on this index. I think the index itself carries some risk, and another issue that worries me is that over the past three or four decades, the S&P index has recorded net inflows every year. We have never experienced a market environment with net outflows from index funds. So I have some concern about this, because investors are now quite saturated with equities across all asset classes. Look at individual investors, look at asset owners what is the world's most crowded ticker? It's the S&P 500 index." Overall, this year has been fairly good for investors, even though at times it hasn't felt that way. The year has been marked by sharp volatility: the U.S.-Iran war triggered an aggressive oil price shock, pushing crude above $100 per barrel and reigniting stubborn headline inflation. To combat persistent price pressures (as shown, for example, by today's October CPI data), Fed Chair Kevin Warsh launched the first rate hike of this cycle in September, raising the policy rate to 3.75% to 4%. Now, calls are rising for the Fed to raise rates by 50 basis points at its final policy meeting in December. Meanwhile, an unprecedented AI boom in the first half of the year pushed tech stock valuations and hyperscaler capital expenditures into overdrive. That euphoria turned sharply into a violent collapse after autumn began: slowing data center approvals, the shift in the landscape brought by Election Day, and surging debt financing costs triggered a sharp compression in valuation multiples and historic selloffs for chipmakers and neocloud providers. The S&P 500 is up 9.5% year to date, outperforming the Dow Jones Industrial Average's 8.5% gain and the Nasdaq Composite's 7.5% advance. Subramanian warned: "So, if you need to raise funds to meet payout obligations or the like, I think that is exactly where outflows become interesting. And that is precisely where we see some risk to the argument that 'the S&P 500 will only keep going up.'"
