美股反弹了，但年底大涨也不用指望？

Core Viewpoint - The U.S. stock market appears to be stabilizing after a recent sell-off, despite disruptions caused by the Chicago Mercantile Exchange outage [1] Group 1: Market Dynamics - Bloomberg macro strategist Simon White indicates that the upward momentum in the U.S. stock market is waning, and the likelihood of a strong year-end rebound is minimal due to significantly reduced buyback activity [2] - The market has shifted from a focus on "momentum" and "trading" factors to a resurgence of the "value" factor, which has taken the lead, while the previously dominant "trading" factor has plummeted to the bottom [3] Group 2: Corporate Buybacks - The corporate buyback trend, a key driver of the current bull market, is rapidly declining. Although November and December are typically strong months for buybacks, the ability of tech giants to continue large-scale buybacks is constrained due to aggressive capital expenditures throughout the year [4] - The "momentum factor" is currently underperforming compared to the S&P 500 index, indicating a potential risk for year-end market performance [5] Group 3: Market Conditions - An analysis of market conditions over the past 25 years shows that the current market is in a "headwind period" characterized by low returns [6] - When the momentum factor outperforms the market, rebounds tend to be healthy and strong. Conversely, when it underperforms, as seen recently, it often corresponds with flat or negative index returns [7] Group 4: Investor Sentiment - Despite the challenges, the overall liquidity in the market remains ample, providing a solid support base for U.S. stocks. However, this does not imply significant upward potential, as weak momentum and limited corporate buyback intentions suggest that expectations for a dramatic year-end rally may be unrealistic [8]
