Applying Science to Investing
Evidence-based investing is the belief that there is a significant body of evidence available to make investment decisions. The evidence suggests there are ways to invest in which we should expect a higher return.

Invest on evidence, not emotion.
Our approach is grounded in decades of peer-reviewed financial science — the same research pioneered by Dimensional Fund Advisors — not headlines, hot tips, or hunches.
Principles applied by Evidence Advisors, built on financial science pioneered by Dimensional Fund Advisors.
A philosophy built on research, not reaction.
Evidence Advisors was founded on a simple idea: investment decisions should be backed by data, not conviction. Rather than chasing headlines or trying to out-guess the market, we build portfolios around principles that decades of financial research have shown to hold up over time.
Here are the core ideas that guide every portfolio we build for our clients.
Embrace market pricing.
Financial markets are remarkably effective information-processing machines. Every day, investors around the world trade an average of $1.1 trillion in stocks, and the resulting prices reflect nearly everything that's known about a company's prospects.1
We start from the belief that prices are, on the whole, fair. Instead of trying to out-think the market, we design portfolios that let its pricing power work for our clients.
Don't try to outguess the market.
Because prices already reflect available information, few professional stock-pickers manage to beat the market consistently. Of nearly 3,000 U.S. stock funds tracked over the 20 years ending 2025, only 12% survived and outperformed their own benchmark. Bond funds fared only slightly better, at 17%.2
The odds simply aren't in the stock-picker's favor — which is why we favor systematic, evidence-driven portfolios over manager bets.
Resist chasing past performance.
It's tempting to invest in whatever performed best last year. But past performance is a poor predictor of future results. Among funds that ranked in the top 25% of returns over a five-year stretch between 2006 and 2025, most didn't hold on to that ranking in the following five years.3
Chasing yesterday's winners is, more often than not, chasing noise.
Let markets work for you.
Patience has historically paid. A dollar invested in U.S. stocks in 1975 would have grown many times over by 2025 — comfortably outpacing inflation, and far outpacing the safety of cash. Bonds, too, have rewarded long-term investors, if more modestly.4
Staying invested — not timing the next headline — is what has actually built wealth over time.
Target higher expected returns.
Decades of academic research have identified certain dimensions of stocks and bonds that are associated with higher expected returns over time.5 We structure client portfolios to systematically emphasize these dimensions, rather than trying to guess which individual stock or bond will outperform.
Company Size
Smaller companies have tended to outperform larger companies over time.
Relative Price
Lower-priced "value" stocks have tended to outperform higher-priced "growth" stocks.
Profitability
Companies with high profitability have tended to outperform those with low profitability.
Term
Wider term spreads have generally led to higher expected returns.
Credit
Wider credit spreads have generally led to higher expected returns.
Currency
Global currencies of issuance can offer opportunities for higher expected returns and reduced volatility.
Diversify internationally.
Limiting a portfolio to your home market means limiting your opportunity set. The S&P 500, for example, covers 500 companies in a single country. A globally diversified portfolio can include more than 8,000 companies across 47 countries.6
That broader footprint puts clients in position to capture higher expected returns wherever they appear, while reducing reliance on any single economy.
Avoid market timing.
There's no reliable way to predict which days the market will post its best returns — and missing even a handful of them can meaningfully hurt long-term results. $1,000 invested in the Russell 3000 Index from 2001 through 2025 grew to $8,360. Miss just the single best week of that 25-year period, and the ending value falls to $6,977. Miss the best six months, and it drops to $5,425.7
Staying invested is what keeps clients in position for the market's best days, since no one can reliably predict when they'll happen.
Look beyond the headlines.
Financial headlines are built to grab attention, not to guide long-term decisions. A steady diet of "funds to buy now" and "the next downturn is coming" can tempt even disciplined investors off course.
When a headline unsettles you, ask whether it's news or entertainment — then tune out the noise and stick to your plan.
Manage your emotions.
Markets rise and fall, and it's natural for emotions to rise and fall with them. Optimism can turn to greed near a market peak, tempting investors to buy in right before a downturn; fear near a market bottom can tempt investors to sell at exactly the wrong time.
Recognizing this cycle — and having a disciplined plan and an advisor to lean on — helps prevent reactive decisions that can derail long-term goals.
Control what you can control.
You can't control which way the market moves next. You can control how your portfolio is built and managed — and that's where we focus.
