最近特斯拉在印度市场的动作引起了我的注意。9月27日，特斯拉公司副总裁陶琳宣布首批由上海超级工厂生产的车辆已在印度正式交付。作为一个长期 关注量化数据的投资者，我惯性地去挖掘这则新闻背后的深层含义。 有趣的是，虽然特斯拉在7月就开设了首家印度展厅，但销量却远低于预期。600多份订单的数字让我不禁思考：这是否意味着印度市场对特斯拉的接受度 存在问题？还是说，高达70%的进口关税才是真正的拦路虎？ 更让我感兴趣的是特斯拉在印度的另一步棋。8月份，他们开始在德里和孟买招聘自动驾驶车辆操作员。这个动作看似不起眼，却透露出一个关键信息： 特斯拉可能把印度视为自动驾驶技术的重要试验场。 这让我想起投资中的一个重要原则：当市场关注点都在A时，聪明的资金往往已经在布局B。特斯拉在印度的策略似乎印证了这一点 - 当大家都在关注销 量时，他们已经在为未来的技术应用铺路。 德意志银行将特斯拉目标价上调至435美元的消息让我更加确信一点：资本市场看重的往往不是当下的业绩，而是未来的可能性。这种前瞻性思维正是量 化投资的精髓所在 - 通过数据挖掘市场尚未充分反映的信息。 这让我联想到一个投资中常见的现象：牛市中的暴跌。很多人看到剧烈调 ...

每当翻开财经新闻，总能看到各路专家指点江山。上周芝加哥大学的调查显示82%经济学家力挺沃勒接任美联储主席，但现实胜算却只有20%。这让我想起 股市里那些言之凿凿的"股神"们——他们说得头头是道，结果往往南辕北辙。今天我们就来聊聊这个有趣的现象。 芝加哥大学布斯商学院的调查结果堪称当代金融界的"罗生门"。82%的经济学家支持沃勒接棒鲍威尔，认为他是最符合"中央银行家"专业形象的候选人。但 讽刺的是，只有20%的人相信他能真正胜出。 这种分裂背后折射出一个残酷现实：在政治面前，专业判断往往要让位。39%的受访者预测白宫国家经济委员会主席哈西特最可能接任，原因无他——只因 这位先生与特朗普的政策立场更契合。 约翰霍普金斯大学教授Robert Barbera一语道破天机："沃勒不迎合政治的姿态，恰恰可能让他出局。"这句话让我想起股市里那些坚持价值投资的基金经理们 ——他们的专业判断常常要屈从于短期排名压力。 这种现象在股市里更是司空见惯。现在资讯发达，"股神"遍地开花。今天喊牛市来了，明天又说熊市将至。他们的套路我太熟悉了： 说到底，市场走势无非涨、跌、横三种可能。但某些专家能用两千字的长文让你看得云里雾里。别怀疑自 ...

- The report introduces a "three-dimensional timing framework" for market analysis, which includes divergence, liquidity, and prosperity indices. This framework is used to assess market trends and predict future movements, indicating a mid-term bullish outlook for the CSI 300 index[7][12][16] - The "Hotspot Trend ETF Strategy" is constructed by selecting ETFs with simultaneous upward trends in their highest and lowest prices. Further filtering is done based on the steepness of the regression coefficients of these prices over the past 20 days. A support-resistance factor is then created, and the top 10 ETFs with the highest turnover rates in the past 5 and 20 days are selected to form a risk-parity portfolio[29][30][33] - The "Funds Flow Resonance Strategy" combines financing net purchases and active large-order funds flow. The financing factor is defined as the market-neutralized financing net purchase minus net short selling, with a 50-day average and two-week rate of change. The active large-order factor is based on the net inflow ranking of industry transaction volumes over the past year, with a 10-day average. The strategy excludes extreme industries and large financial sectors to improve stability. Since 2018, this strategy has achieved an annualized excess return of 13.5% and an IR of 1.7[37][40] - The report tracks multiple style factors, including beta, growth, and value. Beta and growth factors recorded positive returns, with growth achieving a monthly return of 4.74%. Conversely, the value factor showed negative returns, underperforming high-valuation stocks[43][44] - Alpha factors are analyzed across different dimensions, such as time and market capitalization. Factors like "fund holdings relative to float shares" and "top ten holdings relative to net asset value" performed well, achieving weekly excess returns of over 1%. Additionally, research and development-related factors showed strong performance across various indices, with higher excess returns observed in small-cap stocks[47][48][50] - The report highlights the weekly performance of style factors, with beta achieving a return of 2.19%, growth at 1.51%, and value at -1.42%. Other factors like size, momentum, and liquidity also showed varying levels of performance[43][44]

- Profitability and turnover rate factors showed positive performance across all stock pools, delivering positive returns this month[1][10] - Valuation factors demonstrated positive returns outside the CSI 300 stock pool, while growth factors performed well in CSI 300 and CSI 500 but experienced pullbacks in other pools[1][10] - Small-cap factors showed mixed results, achieving positive returns in CSI 300 and CSI 1000 stock pools but pulling back in others[1][10] - Expectation-related factors, such as the "exceed expectations" factor, only delivered positive returns in the CSI 300 stock pool, while "expected valuation" and "expected growth rate" factors showed varied performance across different pools[1][10] - Turnover rate factor led the average long-short portfolio returns this month, especially in CSI 1000 and All-A stock pools[2][15] - Expected net profit growth factor ranked second in long-short portfolio returns, followed by profitability and growth factors, which also delivered positive average returns[2][15] - Other factors, including reversal, valuation, and small-cap factors, showed negative average long-short portfolio returns[2][15] - CSI 1000 index-enhanced funds maintained leading excess returns this month, with median performance significantly ahead of other index-enhanced funds[3][25] - CSI 1000 index-enhanced funds also led in excess returns year-to-date, followed by CSI A500 index-enhanced funds[3][25]

- The non-bank sector confirmed a daily-level decline this week, with the Shanghai Composite Index rising by 0.21% for the week[1][7] - The A-share prosperity index was 22.14 as of September 26, 2025, up 15.83 from the end of 2023, indicating an upward cycle[2][28] - The A-share sentiment index signals were empty for both bottom and top signals, with a comprehensive signal of empty[2][35] - The CSI 500 enhanced portfolio outperformed the benchmark by 0.91% this week, with a cumulative excess return of 50.71% since 2020 and a maximum drawdown of -5.73%[2][44] - The CSI 500 enhanced portfolio's holdings include stocks such as Guojin Securities, Nanjing Iron & Steel, and Perfect World, among others[2][47] - The CSI 300 enhanced portfolio underperformed the benchmark by 0.81% this week, with a cumulative excess return of 37.70% since 2020 and a maximum drawdown of -5.86%[2][51] - The CSI 300 enhanced portfolio's holdings include stocks such as Huaneng International, Founder Securities, and Wuxi AppTec, among others[2][53] - The market style analysis shows that the size factor had a high excess return this week, while the residual volatility factor had a significant negative excess return[5][56] - The style factor performance indicates that high Beta and high growth stocks performed well recently, while residual volatility and value factors performed poorly[5][56] - The main indices' performance attribution shows that the Shanghai Composite Index, SSE 50, and CSI 300 had large exposures to the size factor, while the CSI 500 and Wind All A had smaller exposures[5][61]

通胀阴云笼罩下的华尔街暗流涌动，城堡投资创始人肯·格里芬的一席话让我这个量化投资者陷入了深思。这位金融巨鳄对美国 通胀局势的判断，与我十年来观察到的市场规律不谋而合——表面数据往往掩盖着更深层的真相。 前三次反弹时，"主导动能"显示的是普通的回补行为（蓝色柱体），但缺乏"机构库存"（橙色柱体）的配合。这说明什么？很可 能是散户的自发补仓行为。而第四次反弹时，"回补"行为与持续的"机构库存"同时出现，这才是真正的机构震仓信号。 格里芬指出美国通胀率虽从9%降至2.9%，但实际仍具粘性。这让我联想到股市中的一个奇特现象：牛市中的暴跌往往比熊市更 剧烈。为何会出现这种反直觉的现象？这与格里芬揭示的通胀表象何其相似——市场总是在制造错觉。 人类天生厌恶损失的心理特征，在牛市中表现得淋漓尽致。记得2020年疫情期间的市场波动，多少人因为恐惧而在底部割肉？我 自己也曾犯过这样的错误。直到我开始用数据说话，才发现牛市中的暴跌往往暗藏玄机。 主力资金在牛市中惯用两种手法：一种是真出清，利用市场流动性好的特点快速切换仓位；另一种则是假摔洗盘，通过剧烈震荡 吓退跟风盘。这两种情况在表面走势上几乎一模一样，但背后的资金意图却截然不 ...
