美银Hartnett：市场聚焦美股大涨“迎新”可能性，唯一风险是“市场过于乐观”

Core Viewpoint - The market is beginning to position itself for strong economic growth in 2026, with expectations of interest rate cuts, tax reductions, and tariff cuts driving corporate earnings acceleration [1] Group 1: Market Sentiment and Fund Flows - The Bank of America’s bull-bear sentiment indicator has risen to 8.5, signaling an extreme level of optimism in the market, which may lead to adjustment risks [2][12] - Global stock inflows reached $98.2 billion in a single week, with U.S. stocks attracting $77.9 billion, marking the second-largest weekly inflow on record [5][4] - There was a significant outflow of $43.9 billion from cash assets, the largest since April of this year, indicating a notable increase in market risk appetite [7] Group 2: Investment Strategy - The strategist recommends positioning for a declining inflation trend by going long on zero-coupon bonds, mid-cap stocks, and emerging market equities, rather than simply chasing the current bullish consensus on risk assets [3] Group 3: Macro Outlook and Risks - In an optimistic scenario, if CPI falls to 2% and the 10-year U.S. Treasury yield drops to around 3.5%, risk assets could receive substantial support [8] - Potential risks include global liquidity nearing its peak, the possibility that the Federal Reserve's rate cuts may be less than the market's current expectation of 150 basis points, and the chance of the Bank of Japan raising its policy rate to the highest level since 1995 [9] Group 4: Structural Risks - While overall market positioning does not show overheating, structural risks are accumulating, including high margin debt growth outpacing market gains and elevated hedge fund leverage [17] - The concentration of investor holdings in AI and technology sectors raises concerns reminiscent of market structures in 2000 and 2007 [17] - Global long-term yields are on the rise, posing a risk that could increase bond market volatility and materially threaten the stock market, even if the Federal Reserve continues to cut rates [17]
