看着手机里不断弹出的基金限购公告，我不禁想起十年前刚入行时的困惑。那时的我和大多数散户一样，以为这些公告只是例行公事。直到后来通过量化数 据分析，才发现这背后隐藏着机构资金的精妙布局。 格雷厄姆曾说"牛市是普通投资者亏损的主要原因"，这句话在我十年的投资生涯中不断得到验证。牛市中的暴跌往往让散户措手不及，而机构却能精准把握 进出时机。 以2024年9月24日后的行情为例，表面上指数震荡不前，但个股表现却天差地别。亚辉龙和汇金科技就是最好的对比案例。 汇安基金、湘财久盈等机构的限购措施看似是为了保护投资者利益，实则暗含更深层的市场逻辑。作为一名量化投资者，我发现这些动作往往与机构资金的 季节性调仓密切相关。 记得2015年那轮牛市后的惨痛教训：大多数散户在牛市中亏损高达60%，而同期机构却赚得盆满钵满。这让我深刻认识到，决定股价走势的不是表面的涨 跌，而是背后资金的真实流向。 通过长期跟踪量化数据，我发现一个有趣的现象：A股市场早已告别了齐涨共跌的时代。2016年至2019年间，即便在没有牛市的背景下，个人投资者平均收 益仍为负值，而机构投资者却实现了可观的盈利。 | 同版 | 总收益 | 擇时收益 | 造股收 ...

Report Summary 1. Report Industry Investment Rating No relevant information provided. 2. Core View of the Report - The short - term view of the stock index futures is wide - range oscillation, the medium - term view is upward, and the intraday view is weakly oscillating. The core logic lies in the game between the short - term profit - taking intention of funds and the long - and medium - term fermentation of policy - favorable expectations [1][5]. 3. Summary According to the Catalog 3.1 Variety View Reference - Financial Futures Stock Index Sector - For IH2512, the short - term view is oscillation, the medium - term view is upward, the intraday view is weakly oscillating, and the reference view is wide - range oscillation. The core logic is the game between short - term profit - taking intention of funds and long - and medium - term fermentation of policy - favorable expectations [1]. 3.2 Main Variety Price Market Driving Logic - Financial Futures Stock Index Sector - The intraday view of IF, IH, IC, and IM is weakly oscillating, the medium - term view is upward, and the reference view is wide - range oscillation. Yesterday, all stock indices rose comprehensively, with IC and IM leading the gains. The total turnover of the Shanghai, Shenzhen, and Beijing stock markets was 2347.1 billion yuan, a decrease of 171.3 billion yuan from the previous day. The rebound was accompanied by a reduction in stock market trading volume and a decrease in the open interest of stock index futures, indicating that investors still have differences in their views on the future market. The main trading logic of the stock market comes from policy expectations and capital flows. The game between the profit - taking rhythm of funds and the fermentation of policy expectations needs to be focused on. On one hand, as the valuation has risen significantly, especially when the index rebounds to near the previous high, the demand for profit - taking of profitable funds increases. On the other hand, the policy - favorable expectations and the long - term net inflow trend of the capital side constitute the long - and medium - term driving force for the upward movement of the stock index. The fermentation of policy - favorable expectations depends on the convening of the important meeting in October. The fact that the margin trading balance has exceeded 2.4 trillion yuan and the significant year - on - year increase in new non - bank deposits in July and August indicate the signs of residents' wealth allocation to the equity market. In general, due to the index approaching the previous high and the approaching long holiday, the stock index is expected to be mainly in wide - range oscillation in the short term [5].

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - On September 24, 2025, all stock indices rose, with CSI 500 and CSI 1000 leading the gains. The total trading volume of the Shanghai, Shenzhen, and Beijing stock markets was 234.71 billion yuan, a decrease of 17.13 billion yuan from the previous day. The rebound was accompanied by a contraction in trading volume and a reduction in the positions of stock index futures, indicating that investors still have differences in their views on the future market [3]. - The main trading logic of the stock market currently comes from policy expectations and capital flows. In the future, it is necessary to focus on the game between the profit - taking rhythm of funds and the fermentation of policy expectations. As the valuation has significantly increased, especially when the index rebounds to near the previous high, the demand for profit - taking of profitable funds has increased. On the other hand, the expectation of policy benefits and the long - term net inflow trend of funds constitute the medium - and long - term driving force for the upward movement of stock indices. The fermentation of policy benefits is expected to await the convening of the important meeting in October. The fact that the margin trading balance has exceeded 2.4 trillion yuan and the year - on - year significant increase in new non - bank deposits in July and August indicate that the signs of residents' wealth allocation to the equity market have begun to appear [3]. - In the short term, the stock index is expected to fluctuate widely because the index is close to the previous high and the long holiday is approaching. Currently, the implied volatility of options has declined. Considering the medium - and long - term upward trend of the stock index, investors can continue to hold bull spreads or ratio spreads [3]. 3.
