Two Sigma S&P Rally Signals Easy Money Has Already Been Made

The S&P 500 Index has clawed its way back to all-time highs, but the pace of the rally has slowed markedly from the explosive gains seen in the weeks following the election. According to quantitative investment firm Two Sigma, this shift signals that the 'easy money' phase of the market's advance may already be behind us. The index's return to record territory, while notable, is occurring on thinner breadth and with less conviction than the initial surge, suggesting that investors can no longer rely on a simple rising tide to lift all stocks.

For equity traders, the deceleration in the S&P 500's momentum carries important implications. The initial post-election rally was fueled by a combination of policy optimism, short covering, and a rush of liquidity — conditions that created a broad-based advance where nearly every sector participated. Now, with the index back at highs but the rally losing steam, the market is entering a more selective phase. This is consistent with late-cycle dynamics where earnings yield differentials relative to Treasury yields become a key driver, and where forward P/E multiples face headwinds from rising bond yields. Live stock prices and charts on NowPrice show how the market is reacting, with sector rotation becoming more pronounced as investors seek out specific opportunities rather than buying the whole market.

Looking ahead, traders should watch for a few key signals. First, the breadth of the rally — measured by the percentage of stocks above their 50-day moving average — will indicate whether the advance is sustainable or merely a narrow leadership. Second, any shift in Federal Reserve policy expectations, particularly regarding rate cuts, could reignite or further dampen momentum. Finally, corporate earnings reports in the coming weeks will be critical; if companies fail to deliver on the elevated expectations baked into current valuations, the market may struggle to hold these highs. The easy gains have been made; the next leg will require genuine fundamental catalysts.
