    AQR: Common Misconceptions About Tax-Aware Long-Short Investing (Part 2) — The Misleading Analogy to Direct Indexing

    AQR has published the second installment of its research series on tax-aware long-short (TA LS) investing, clarifying two misconceptions arising from analogies to direct indexing. First, the tax benefits of TA LS come primarily from deferred capital gains rather than active loss harvesting: its loss realization pace is similar to ordinary tax-insensitive strategies, and tax-aware optimization is mainly used to avoid selling positions with existing unrealized gains, especially short-term gains.

    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.

    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.

    Bridgewater: Inflation Risks Enter a New Era of Structural Uptrend

    Bridgewater released a research report, arguing that the inflation center in the post-pandemic era has risen compared with that before the pandemic, 2% is more like a bottom than an upper limit, and the distribution of inflation outcomes is wider and skewed upward. The report compares the current environment with that in the 2010s, pointing out that restraining factors such as China's export of low-priced goods, shale oil production, and post-crisis deleveraging have weakened; while the medium-term expansion deficit of about 7% of US GDP, the compromised independence of the Federal Reserve, tariffs and trade restructuring, potential depreciation of the US dollar, and AI power and commodity demand constitute structural inflationary pressures.

    What Does It Take to Revive U.S. Manufacturing? Part 2: Boosting U.S. Manufacturing Productivity

    Bridgewater, in collaboration with Eclipse, released the second part of its series on reviving U.S. manufacturing, pointing out that U.S. manufacturing lacks competitiveness due to high labor costs and a weak industrial base, and tariffs cannot bridge the cost gap. The report proposes leveraging mature technologies such as automation, computer vision, and additive manufacturing, as well as cutting-edge technologies like generative AI and embodied AI, to boost manufacturing productivity by 1 to 2 orders of magnitude. Scaling the application of these technologies is expected to take nearly a decade.

    What Does It Take to Revive U.S. Manufacturing? Part 1: Structural Headwinds Facing the United States

    Bridgewater, in partnership with industrial technology investment firm Eclipse, released a study exploring the structural challenges of reviving U.S. manufacturing. Currently, about 40% of goods consumed in the U.S. rely on imports, with a manufacturing job gap of nearly 5 million over the past 20 years. For some product categories, even a 25% tariff cannot close the gap between domestic and foreign production costs. U.S. manufacturing productivity has stagnated for 15 years, and boosting productivity is the core path to enhancing the competitiveness of domestic manufacturing.

    Bridgewater Research: Drivers of U.S. Stock Outperformance and Conditions Needed for Future Repeats

    Bridgewater research indicates that since 2010, the excess returns of U.S. stocks relative to developed markets have been roughly equally driven by revenue growth, margin expansion, and rising P/E multiples, with a stronger U.S. dollar further boosting returns for unhedged global investors. The technology sector contributed 54% of the excess returns, of which 22% came from index overweights in technology and 32% from U.S. tech companies significantly outperforming their global peers.
