The Numbers Are In: Flexible Trading Helps Across Markets
Investing in the real world incurs costs, and costs matter for the returns investors get.
Dimensional uses a flexible trading approach that seeks to reduce costs. This flexibility starts with our investment philosophy. We seek to add value by systematically emphasizing groups of stocks with higher expected returns rather than by identifying mispriced securities. As a result, we can consider many securities with similar characteristics as close substitutes for one another. Our flexible trading approach is also empowered by our thoughtful portfolio implementation. We structure our portfolios to focus on long-term drivers of returns—such as company size, relative price, and profitability—which do not require high turnover. We incorporate information from shorter-term drivers of returns, such as momentum and securities lending fees, by delaying buys and/or sells of securities rather than by chasing fast-dissipating signals. And we seek to rebalance our portfolios incrementally each day using up-to-date information. All of this enables us to participate daily in the available market liquidity and avoid demanding immediacy.
In a new study, we examine the trading price advantages of our flexible approach after tracking trade data over the 2017–2020 period across 46 stock markets. As shown in Exhibit1, Dimensional’s average price advantages—measured by our trading prices relative to those obtained by market participants who demand immediacy—were pervasive across markets and persistent over time. Our price advantage was 10.5 basis points (bps)1 on average over the period, ranging from 4.3 bps for US large cap stocks to 24.8 bps for emerging markets small cap stocks. Furthermore, our longstanding flexibility can be more valuable when volatility is high. Indeed, we see that the price advantages increased as much as 100% in times of extreme return volatility, like March 2020.
