聚焦ETF市场 | 投资者逢低买入屡试不爽，已成牛市引擎？

Core Viewpoint - The "buying the dip" strategy remains prevalent and has become institutionalized, with increased investor confidence leading to significant inflows into ETFs following market downturns, surpassing the enthusiasm seen in 2021 [4][9]. Group 1: ETF Investor Behavior - ETF investors are increasingly viewing market pullbacks as opportunities rather than risks, leading to accelerated inflows during declines, similar to the frenzy of 2021 but more disciplined [7][9]. - The S&P 500 index experienced a record of 354 consecutive trading days without a drop exceeding 2%, contributing to a reduced number of buying opportunities [9][10]. Group 2: Effectiveness of the "Buying the Dip" Strategy - Historically, the effectiveness of the "buying the dip" strategy is attributed to the long-term upward trend of the stock market, with the S&P 500 ETF (SPY) averaging a 0.56% increase in the week following a decline, with over half of the time resulting in a rebound [9]. - The intensity of the "buying the dip" behavior is influenced by the frequency of market pullbacks, with fewer opportunities observed in 2024 compared to the frequent declines of 2020-2021 [9].
