Is it reasonable to assume that strong earnings growth and price-to-earnings ratio (P/E) expansion will sustain the unusually strong U.S. stock market returns of the past decade? In his brief September 2025 paper entitled “Expected Stock Returns in Bullish Times”, Javier Estrada decomposes stock returns into: (1) dividend yield, (2) change in earnings and (3) change in P/E. He then employs this decomposition to compare the bullish environments at the end of the 1990s with that of the summer of 2025, including an outlook for the next decade. Using Robert Shiller’s prices, earnings and dividends for the S&P Composite Index during 1872 through June 2025, he finds that: Keep Reading

How can investors and fund managers best exploit premiums associated with value, momentum, profitability, investment and low volatility factors, either to generate absolute return or to beat a market benchmark? In his September 2025 paper entitled “Strategic Style Allocation: Absolute or Relative?”, Pim van Vliet examines strategic allocation across long-only, value-weighted versions of these equity factors, depending on objective: absolute return or benchmark outperformance. To assess absolute return, he evaluates Sharpe ratios of factor allocations. To assess benchmark outperformance, he evaluates information ratios of factor allocations. He also investigates dynamic allocation between low volatility and the other factors, with portfolio adjustment frictions. Using long-only U.S. value-weighted factor returns during July 1963 through May 2025 and global factor index returns during January 1999 through March 2025, he finds that: Keep Reading

Are the “Simple Asset Class ETF Value Strategy” (SACEVS) and the “Simple Asset Class ETF Momentum Strategy” (SACEMS) mutually diversifying. To check, based on feedback from subscribers about combinations of interest, we look at three equal-weighted (50-50) combinations of the two strategies, rebalanced monthly:

1. 50-50 Best Value – EW Top 2: SACEVS Best Value paired with SACEMS Equally Weighted (EW) Top 2 (aggressive value and somewhat aggressive momentum).
2. 50-50 Best Value – EW Top 3: SACEVS Best Value paired with SACEMS EW Top 3 (aggressive value and diversified momentum).
3. 50-50 Weighted – EW Top 3: SACEVS Weighted paired with SACEMS EW Top 3 (diversified value and diversified momentum).

We consider as a benchmark a simple technical strategy (SPY:SMA10) that holds SPDR S&P 500 ETF Trust (SPY) when the S&P 500 Index is above its 10-month simple moving average and 3-month U.S. Treasury bills (Cash, or T-bills) when below. We also test sensitivity of results to deviating from equal SACEVS-SACEMS weights. Using monthly gross returns for SACEVS, SACEMS, SPY and T-bills during July 2006 through August 2025, we find that: Keep Reading

“Compendium of Live ETF Factor/Niche Premium Capture Tests” summarizes results for its eponymous title. Here we add a live test of the short-term reversal effect among U.S. stocks. Specifically, we examine the performance of the now dead Vesper U.S. Large Cap Short-Term Reversal Strategy ETF (UTRN), designed to track the performance of a portfolio of 25 of the 500 largest U.S.-listed stocks most likely benefit from the short-term reversal effect. We use SPDR S&P 500 ETF Trust (SPY) as the benchmark. We focus on monthly return statistics, along with compound annual growth rates (CAGR) and maximum drawdowns (MaxDD). Using monthly total returns for UTRN and SPY during September 2018 (UTRN inception) through March 2025 (UTRN death), we find that:

Is relevant news sentiment from other countries additive to local news in predicting country stock market returns? In their August 2025 paper entitled “Global News Networks and Return Predictability”, Gustavo Freire, Ali Moin, Alberto Quaini and Amar Soebhag compare the effects of local versus global news sentiment, organized into 260 major themes, on country stock market returns. They apply random forest machine learning to news sentiment variables to construct out-of-sample market timing strategies based on local versus global sentiment measures. Specifically, they:

• Fit random forests on the initial 18 months of local or global data to select base models.
• Use the next six months to select optimal hyperparameters.
• Retrain the model every 20 trading days with an expanding window, so that each new fit uses all data up to the end of the previous month.
• Each day for each country market, go long (short) that market for that day if its projected return is positive (negative).

Using Global Knowledge Graph Database news sentiment data for 520 million articles from 14 developed countries and associated country market returns computed from futures contract prices for 14 equity indexes during February 2015 through December 2023, they find that:

Does alignment of return-based factors with informed traders and against noise traders produce a superior model of stock returns? In his August 2025 paper entitled “An Auto-Residual Factor Model”, Malek Alkshaik introduces and tests a 5-factor Auto-Residual Factor Model of stock returns comprised of: market excess return; market capitalization (size); residual short-term reversal (last month); residual momentum (measured from 12 months ago to one month ago): and, residual long-term reversion (measured from 24 months ago to 13 months ago). This model uses no firm fundamental data. He postulates that the latter three factors occur due to interactions between noise traders and informed traders. He calculates (purifies) residuals via regressions against five principal components derived from the last 24 months of returns for all stocks, thereby aligning residuals with informed traders and against noise traders (purifying). He emphasizes maximum squared Sharpe ratio (based on mean-variance optimal factor allocations) to compare the new model to seven widely used alternatives. Using a main sample of U.S. listed common stocks during 1972 through 2022, plus a 1932 through 1971 U.S. sample and a 1992 through 2022 global sample for robustness tests, he finds that:

Should investors relish opportunities to invest in private equity? In his July 2025 paper entitled “The Private Equity Illusion: Revisiting Risks, Returns, and Realities”, Simon Nocera analyzes the narrative that private equity is a superior asset class that delivers higher returns at lower risk than, and diversifies, public equity markets. Using investment industry data, academic research, consulting reports and empirical data focused on the last decade, he finds that:

Does the ICE BofAML MOVE Index, the implied volatility of U.S. Treasuries as derived from options on U.S. Treasuries with maturities 2, 5, 10 and 30 years, usefully predict U.S. stock market and U.S. Treasury bond returns? To investigate, we perform two sets of calculations using SPDR S&P 500 ETF (SPY) as a proxy for the U.S. stock market and iShares 20+ Year Treasury Bond ETF (TLT) as a proxy for U.S. Treasury bonds:

1. Lead-lag analyses using correlations between end-of-month MOVE Index or change in MOVE Index and monthly SPY or TLT returns.
2. Average next-month SPY or TLT returns by ranked fifth (quintile) of end-of-month MOVE Index or change in MOVE Index.

Using end-month MOVE Index levels and monthly dividend-adjusted SPY and TLT data during November 2002 (limited by MOVE Index data) through August 2025, we find that: Keep Reading

Are equity multifactor strategies, as implemented by exchange-traded funds (ETF), attractive? To investigate, we consider eight multifactor ETFs, all currently available:
