    A veteran former fund manager used AI to test his lifelong investment strategy

    A former equity strategy partner and independent investment firm operator used AI in retirement to backtest his long-standing personal strategy, which combined Peter Lynch's growth stock selection, Hilary Kramer's undervalued obscure stock selection, and earnings revision discipline. He corrected for survivorship bias, used point-in-time data, calculated pre-fee returns, and compared it against random stock selection from the same investment pool. The results showed that the strategy did not outperform random selection, with ordinary index funds performing better than the strategy.

    Damodaran: AI Capital Expenditure Effects Emerge, US Stocks Remain Supported Despite Rising Treasury Yields in September

    New York University Professor Aswath Damodaran reviewed the performance of US stocks in September 2026: the 10-year US Treasury yield rose from 4.75% to 5.29% during the month, an increase of 54 basis points, placing it in the top 10% of 770 monthly changes since 1962. Despite this, the total market capitalization of US stocks still increased by $2.5 trillion during the month, with nearly $1.5 trillion of that increase coming from the technology sector.

    Fed Governor Waller: The Signal Value of the Summary of Economic Projections and the Logic Behind the September Rate Hike Decision

    Fed Governor Waller delivered a speech at the Central Bank of Türkiye, explaining the rationale behind the September FOMC decision to raise the policy rate by 25 basis points to 3.75%-4%, and elaborating on the signaling role of the Summary of Economic Projections (SEP). He stated that the September rate hike was not based on a single inflation data point, but rather the cumulative result of multiple factors over recent months, including stabilization in the labor market, energy price increases driven by Middle East conflicts, high-tech consumer price increases driven by AI construction, and new tariff risks arising from trade conflicts.

    Fed Governor Lisa Cook: The Dual Mission in Rural America

    Federal Reserve Governor Lisa Cook delivered remarks at the first nationwide Investing in Rural America conference hosted by the Federal Reserve Bank of Richmond. She noted that rural labor markets broadly track national trends, but with lower labor force participation and slower employment growth than urban areas in recent years. Rural inflation has largely aligned with national trends, though cost-of-living increases outpaced urban areas during the post-pandemic recovery, with energy and housing costs as the primary sources of divergence.

    Howard Marks' Latest Memo: Should We Abolish the Laws of Economics (Part III)

    In his latest memo, Howard Marks explores recent attempts to suppress long-term government bond yields. He states clearly that the only sustainable solution is to address the underlying factors driving interest rates higher, even if such measures face political resistance. Any other approach is essentially an attempt to defy the laws of economics, and such attempts have never succeeded.

    Damodaran: Re-examining the Relationship Between Rising Interest Rates and Stock Prices in 2026

    NYU Professor Aswath Damodaran reviews the backdrop of rising U.S. Treasury yields in 2026, noting that the 10-year Treasury yield rose from 4.18% at the start of the year to 4.75% by the end of August, while 20-year and 30-year Treasury yields surpassed 5% during the year. He also compares the long-term trend of U.S. Treasury yields since 1962, as well as concurrent changes in government bond yields across multiple currencies, including the euro, Japanese yen, and British pound.

    Key Takeaways:One can learn to construct an intrinsic risk-free rate using the inflation rate plus real GDP growth, and combine it with changes in corporate cash flows to break down the differentiated impact of rising interest rates on stock valuations across industries.

    The core competitiveness of quantitative investment in the AI era lies in human creativity and emotional intelligence

    AQR co-founder and dean of Northwestern University’s Kellogg School of Management co-authored an article pointing out that AI can automate most analytical and technical capabilities in quantitative investment, making creativity and emotional intelligence enduring competitive advantages that are difficult to replace. AQR is leveraging the Quanta Academy, launched in 2015, to expand relevant capability development, while Kellogg School of Management also promotes students’ simultaneous development of analytical skills and soft skills through programs such as MBAi. Research shows that the impact of AI on empathy is not fixed, and depends on tool design choices and organizational culture building.

    Aswath Damodaran analyzes the tradeoff between expansion and profitability: the weakest link in venture capital

    Aswath Damodaran, a professor at NYU Stern School of Business, writes that the current venture capital industry generally prioritizes corporate expansion over profitability, a tendency that has become more pronounced over the past two decades. He breaks down six core factors influencing a company's expansion potential, including market size, market growth rate, industry structure, capital intensity, customer inertia, and dependence on key individuals. He also identifies the key variables determining a company's profitability feasibility as unit economics, economies of scale, and competitive barriers.

    Key Takeaways:You can master an analytical framework that distinguishes between a company's expansion potential and profitability feasibility, using market size, unit economics, economies of scale, and competitive barriers to judge whether a startup's expansion choices are reasonable.

Six leading AI companies have cumulatively spent $1.7 trillion in capital expenditures, while the current upper bound of total revenue from AI products and services is only about $250 billion.

    Data mining and AI-driven 'quant by feel' are essentially the same in quantitative trading; the core should focus on the structural source of trading edge.

    The article points out that data mining and AI-driven 'quant by feel' are identical in essence and philosophy, both attempting to skip the core step of understanding how markets work and profit directly from the market. A genuine trading edge requires identifying the counterparty being profited from, the reason they continue to pay, and the rationale for one's own ability to participate in the trade; such structural edge cannot be identified through backtesting optimization alone.

    In his latest memo, Howard Marks outlines the evolution of the sub-investment grade credit market from the 1970s to the present, focusing on analyzing the drivers behind the rapid growth of direct lending after the global financial crisis, as well as the related issues brought by the rapid deployment of large-scale capital. He points out that the development of direct lending is deeply tied to that of private equity, and the performance of private equity portfolio companies is the core determinant of whether direct loans will succeed in the future.

    Brave New Backtest: Why LLMs Have Three Structural Limitations in Trading Research

    Drawing on two academic papers, the author identifies three structural limitations of using LLMs in trading research: First, training data is saturated with trading common sense and lacks mechanism-driven edge thinking. Second, across 35+ models, accuracy in time-series value tracking declines logarithmically as the number of historical updates increases, and neither prompt engineering nor expanding the context window can fix this. Third, outputs from 25+ models on open-ended questions show 71%–82% similarity, and models with different architectures converge to the same common answers.

    AI Will Create Millions of Quantitative Traders, Most of Whom Will Lose Money

    The author notes that AI has dramatically lowered the barrier to developing quantitative strategies, enabling fully coded and backtested strategies to be generated within minutes. However, cheap experimentation amplifies the multiple-testing problem, producing a flood of false backtest results that appear effective but are actually overfit to noise.
