Alpha Architect interprets Dmitriy Muravyev's 2026 working paper, which uses an in-house LLM replication pipeline to reconstruct the core results of 1,328 papers published in the Journal of Finance, Journal of Financial Economics, and Review of Financial Studies between 2000 and 2020, of which 1,005 were eligible for subsequent out-of-sample testing.
Read originalAQR has released the third part of its research series on tax-aware long-short (TA LS) strategies, clarifying two common misconceptions. As an active investment strategy, TA LS deliberately retains tracking error to express alpha models and capture excess returns and tax deferral benefits, rather than minimizing tracking error like direct indexing. Portfolio construction for TA LS requires balancing expected returns, risk, costs, and taxes, rather than simply realizing capital losses or deferring capital gains.
Read originalAnalysis of 401(k) plan filings from 2013 to 2023 by the CFA Institute Research and Policy Center shows that the average expense ratio of 401(k) investment menus fell from 0.69% to 0.39%, with declines in both active and index fund fees, and the fee gap between small and large plans has essentially closed. Fund quality also improved over the same period, with the weighted average of Morningstar Medalist ratings rising from 3.45 to 3.85, and lower-cost funds often receiving higher ratings.
Read originalThis article treats the holding costs, behavioral pressures, and governance burdens of tail risk hedging during calm periods as design constraints rather than post-hoc inconveniences. The authors first break down three types of "bleeding" sources: direct holding costs, opportunity costs, and evaluation pressure, and provide a table of cumulative sleeve losses for different annualized carry rates over 3 to 15 years, as well as a table of portfolio-level annual drag converted by sleeve weight.

Read originalQuantocracy has compiled recent quantitative research-related links as of October 5, 2026, covering 5 quantitative research pieces on different topics. The content includes a study on the century-long history of meme stocks, methods for constructing statistically valid backtests, market reactions following analyst downgrades, a comparison of 200-day moving average and volatility targeting strategies, and an introduction to the Orthogonal Clustering Risk Parity (OCRP) strategy.
Read originalAlpha Architect interprets the paper "Competition, complexity, and security design: evidence from retail investment products" published in the Review of Finance in 2026. This study takes yield-enhancement products in the Swiss market as a sample and finds that issuers deliberately increase product complexity to weaken price competition when competition intensifies.
Read originalThe SSRN paper "A Century of Meme Stocks and the Price of Coordination" proposes training machine learning models using market and company data to identify meme stocks, extending the traceable "memeness" indicator back to 1926.
Read originalQuantocracy compiled recent links related to quantitative research on October 3, 2026, covering five topics: a backtest of Warren Buffett's contrarian investment advice, the performance of a Nasdaq-100 polynomial regression band strategy, the causes of the asset growth anomaly, a test of the U.S. stock turn-of-the-month effect, and a method for calculating transaction costs in macro trading strategies.
Read originalQuantocracy has compiled the latest links related to quantitative research as of October 2, 2026, covering a range of quantitative research topics. These include 897,000 tests conducted on approximately 150 types of trading patterns, an analysis of the impact of 13 oil price surges on U.S. stocks since 1970, a study of asset performance during periods of rising bond yields from 1963 to 2026, and research on an attention factor based on the WallStreetBets herding effect and BERT sentiment.

Read originalThe Quantpedia Awards 2027 is now open, with a total prize pool of USD 25,000, for quantitative research papers published on open-access platforms such as SSRN and arXiv between May 1 and December 31, 2026.
Read originalBlock Scholes has released its Week 40 crypto derivatives market analysis report, noting that against a macro backdrop of rising oil prices, the ongoing U.S.-Iran Strait of Hormuz standoff, and deepening U.S. Treasury sell-offs, BTC prices have consolidated in the $82,000 to $84,000 range, while spot BTC and ETH ETFs have recorded net capital inflows for over 7 consecutive days.
Read originalAQR 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.
Read originalBridgewater released a research report pointing out that current carbon pricing mechanisms cover approximately 30% of global emissions, mainly dominated by the emissions trading systems of the European Union and China. The EU Carbon Border Adjustment Mechanism (CBAM) is amplifying its impact and promoting the adoption of carbon pricing worldwide.
Read originalAQR has published a research article noting that the market often incorrectly analogizes tax-aware long-short investing (TA LS) to direct indexing strategies, clarifying two core misconceptions.
Read originalBlock Scholes released its Week 38 crypto derivatives market analysis report. The current market prices in a 93% probability of a rate hike at the Fed's next-day meeting, while the probability of the Clarity Act passing by the end of 2026 on Polymarket has dropped to 19%.
Read originalAQR has updated its previous analysis of inflation sensitivity and inflation hedging, based on over 50 years of market data. While global inflation has fallen rapidly from its 2022 peak, inflation uncertainty persists in major markets, stock-bond correlations are at multi-decade highs, and traditional stock-bond portfolios are vulnerable to simultaneous losses during inflation shocks. Commodities and trend-following strategies perform strongly during inflation upcycles and can serve as inflation diversification tools, with implementation methods significantly affecting long-term returns and macro diversification outcomes.
Read originalAQR’s latest research, "Liquidity without Liquidation", shows that tax-sensitive long-short strategies can extract large amounts of cash without fully liquidating the portfolio, while maintaining pre-tax returns, target tracking error, and leverage levels.
