When it comes to investing, what you invest in is undeniably important. However, how those investments are chosen behind the scenes matters just as much, if not more.
At Donalies Financial Planning, our approach to fund selection is intentional, evidence-based, and specifically designed to support long-term financial success rather than chasing short-term headlines. Below is a clear overview of exactly how we choose the investment funds for your portfolio, and why we primarily utilize Vanguard, Dimensional Fund Advisors (DFA), and Exchange-Traded Funds (ETFs) instead of traditional, actively managed mutual funds.
Our Investment Philosophy: Evidence Over Excitement
We build portfolios based on decades of rigorous academic research, not market predictions, gut feelings, or the latest Wall Street trends. When you strip away the noise, the historical evidence consistently shows us a few undeniable truths:
Markets are highly competitive: They incorporate new information almost instantly, making it incredibly hard to find "mispriced" stocks.
Outperformance is rare: Consistently beating the market through active stock picking is extremely difficult over long periods.
Controllables matter most: Costs, taxes, and investor discipline matter far more to your bottom line than trying to “beat” the market.
As a result, our focus is on capturing market returns efficiently, managing risk thoughtfully, and ensuring our clients stay invested through all market environments in order to reach their goals.
Why We Prefer Vanguard and Dimensional Fund Advisors (DFA)
There are thousands of fund families out there, but we consistently lean on Vanguard and DFA. Here is why:
1. Low Costs Matter More Than Most Investors Realize Investment costs are one of the few variables in investing that we can absolutely control. Lower expense ratios mean more of your return stays in your portfolio to compound over time, rather than going to fund managers. Vanguard and DFA are industry pioneers in cost efficiency. Over a 10, 20, or 30-year retirement timeline, those saved fractions of a percent compound into highly meaningful wealth.
2. Broad Diversification Reduces Unnecessary Risk Rather than betting your financial future on a handful of individual stocks or narrow, trendy sectors, we favor funds that provide massive, global exposure.
By using funds that hold thousands of companies across multiple countries, regions, sizes, and styles, Vanguard and DFA excel at disciplined diversification. This dramatically reduces the risk that any single company’s failure or a specific market segment's downturn will derail your plan.
3. Evidence-Based Portfolio Construction DFA, in particular, is known for its deep, foundational connection to academic research. Their funds are designed around well-documented drivers of long-term returns, often referred to as "factors"—such as:
Company size: Small-cap companies have historically outperformed large-cap companies over the long run.
Relative value: Value companies (priced lower relative to their book value) have historically outperformed growth companies.
Profitability: Companies with robust profitability tend to perform better.
This approach completely avoids speculation and instead tilts your portfolio toward factors supported by decades of peer-reviewed data.
4. Long-Term Discipline Built Into the Funds Unlike many active managers who trade constantly, Vanguard and DFA do not attempt to time the market or react emotionally to short-term news. This built-in discipline helps you stay aligned with your long-term plan, even when the markets get choppy.
Why We Use ETFs Instead of Traditional Mutual Funds
While mutual funds and ETFs can look similar on the surface, Exchange-Traded Funds offer distinct, meaningful advantages for our clients.
Why ETFs Are a Smart Tax Move ETFs are a fantastic tool for growing your wealth, especially in a taxable brokerage account. Here is a simple breakdown of why they are inherently tax-efficient:
No "Surprise" Tax Bills: Traditional mutual funds sometimes force you to pay taxes on capital gains, even if you didn't sell any of your own shares! ETFs have a unique trading structure behind the scenes that shields you from other investors' actions, keeping your money invested instead of going to the IRS.
Less Churn, Less Tax: Most ETFs simply track a specific market index. Because there isn't a fund manager constantly buying and selling stocks inside the fund to try and beat the market, far fewer taxable events are triggered.
You Are in Control: With an ETF, you generally only pay capital gains taxes when you decide to sell your shares at a profit. This puts you in the driver's seat, allowing your investments to compound and grow without unnecessary tax drag along the way.
Lower Ongoing Costs and Total Transparency Beyond taxes, ETFs typically boast even lower expense ratios than comparable mutual funds. Furthermore, ETFs trade throughout the day and clearly disclose their holdings daily, offering greater transparency into exactly what you own.
Why We Avoid Actively Managed Mutual Funds
Many traditional, actively managed mutual funds aim to outperform the market, but the data tells a very different story.
Most active managers underperform their benchmarks over time. To make matters worse, past performance is notoriously unreliable; the "star manager" of the last five years is rarely the star of the next five. When you factor in the higher fees and increased trading costs associated with active management, it creates a significant headwind for your returns. Rather than relying on manager selection or market forecasts, we focus on a repeatable process that has historically delivered better outcomes.
The Bottom Line
Our entire fund selection process is guided by one core question: “What gives our clients the highest probability of long-term success?”
The evidence leads us straight to Vanguard and DFA for their low costs and discipline, ETFs for their incredible tax efficiency and transparency, and a rules-based approach grounded in reality. By controlling what we can, costs, diversification, taxes, and behavior, we help you stay focused on what truly matters: reaching your financial goals with confidence.
