Abstract:Goldman Sachs reviews a stellar 2025 but warns 2026 will be "wilder," characterized by 0DTE option-driven volatility and thinning market breadth despite strong earnings.

After a bellwether year where the S&P 500 delivered double-digit returns and an 8-month winning streak, Goldman Sachs Global Head of Hedge Funds, Tony Pasquariello, is advising clients to embrace a regime of higher volatility.
While describing 2025 as “Very Good” on paper, Pasquariello notes the divergence between index performance and the difficulty of trading it. The Nasdaq 100 surged 21%, but realized volatility spiked to 19% (83rd historical percentile), and one-third of index constituents actually finished the year in the red.
Pasquariello predicts 2026 will see a continuation of the bull market but with significantly more violent price action.
1. Valuations: The S&P 500 P/E ratio has expanded from 21.5x to 22.0x, leaving little margin for error.
2. Breadth: The “Magnificent 7” trade is showing fatigue. While Google (+65%) and Nvidia (+39%) outperformed, the law of large numbers is capping momentum. Nvidia alone added—and then lost—$1 trillion in market cap within a seven-week window, exemplifying the fragility of current leadership.
3. Liquidity Structure: The explosion of 0DTE (Zero Days to Expiration) options, which now account for nearly two-thirds of short-dated volume, is creating “gamma traps” that exacerbate intraday moves and create sudden liquidity vacuums.
Despite the volatility, the “floor” for equities remains earnings growth. 14 percentage points of the S&Ps 2025 return was driven by EPS growth, proving that corporate America has successfully navigated the high-rate environment. However, with sovereign debt swelling and AI capital earning expectations sky-high, the simple “buy and hold” strategy may underperform tactical, active management in the year ahead.
