Building a Better Portfolio to Create a Better Investment Experience
1 | Embrace market pricing
- The market is an effective, information-processing machine. Millions of participants buy and sell securities around the world markets every day, and the real-time information they bring helps set prices.
2 | Don’t try to outguess the market
- The market’s pricing power generally works against mutual fund managers who try to outsmart other participants through stock picking or market timing.
3 | Resist chasing past performance
- Some investors select mutual funds based on past returns. However, funds that have outperformed in the past do not always persist as winners. Past performance alone provides little insight into a fund’s ability to outperform in the future.
4 | Let markets work for you
- The financial markets generally have rewarded long-term investors.
5 | Consider the drivers of returns
- Academic research has identified these equity and fixed income dimension, which point to differences in expected returns.
6 | Practice smart diversification
- Diversification helps reduce risks that have no expected return, but diversifying within your home market is not enough. Global diversification can broaden your investment universe.
7 | Avoid market timing
- You never know which market segments will outperform from year to year. By holding a globally diversified portfolio, investors are well positioned to seek returns wherever they occur.
8 | Manage your emotions
- Many people struggle to separate their emotions from investing. Markets go up and down. Reacting to current market conditions may lead to making poor investment decisions at the worst times.
9 | Look beyond the headlines
- Daily market news and commentary can challenge your investment discipline. Some messages stir anxiety about the future while others tempt you to chase the latest investment fad. When tested, consider the source and maintain a long-term perspective.
10 | Focus on what you control
- Make the most of the things you control but be sure to evaluate factors that are somewhat or completely out of your control.
Create an investment plan to fit your needs and risk tolerance
- Diversify broadly
- Reduce expense and turnover
- Minimize taxes
Applying Science to Investing
Because you cannot control the market, you need a plan that gives you the highest probability of being able to achieve your long-term plan and to seek to realize your most deeply held goals.
Exhibit 1: In USD. Source: Dimensional, using data from Bloomberg LP. Includes primary and secondary exchange trading volume globally for equities. ETFs and funds are excluded. Daily averages were computed by calculating the trading volume of each stock daily as the closing price multiplied by shares traded that day. All such trading volume is summed up and divided by 252 as an approximate number of annual trading days.
Exhibit 2: The sample includes funds at the beginning of the 20-year period ending December 31, 2019. Each fund is evaluated relative to its respective primary prospectus benchmark as of the end of the evaluation period. Surviving funds are those with return observations for every month of the evaluation period. Winner funds are those that survived and whose cumulative net return over the period exceeded that of their respective primary prospectus benchmark. Loser funds are funds that did not survive the period or whose cumulative net return did not exceed that of their respective primary prospectus benchmark. Where the full series of primary prospectus benchmark returns is unavailable, non-Dimensional funds are instead evaluated relative to the Morningstar category index assigned to the fund’s category at the start of the evaluation period.
Exhibit 3: This study evaluated fund performance persistence over rolling periods from 2000 through 2019. Each year, funds are sorted within their category based on their previous five-year total return. Those ranked in the top quartile of returns are evaluated over the following five-year period. The chart shows the average percentage of top-ranked equity and fixed income funds that kept their top ranking in the subsequent period.
