An Idea for an Ultimate 3‑Fund Portfolio (and Two Smart Complements)

Why simplicity still wins — and how a few thoughtful additions can round out your exposure

Before we get into the details, a quick reminder: this isn’t financial advice, a recommendation, or a claim that you should invest in any of the ETFs mentioned. We’re simply sharing a framework we’ve personally explored and invested in before. Markets are unpredictable, forecasts are never guarantees, and every investor should do their own research and understand the risks involved.

With that out of the way, let’s talk about something we’ve always found fascinating: the idea of a clean, resilient, and easy‑to‑maintain 3‑fund portfolio — and how two additional ETFs can round it out into something surprisingly complete.

Why a 3‑Fund Portfolio Still Works

There’s a reason the “three‑fund portfolio” has become a classic. It’s simple, diversified, and easy to stick with during the emotional rollercoaster that markets inevitably put us through. As Warren Buffett famously said, “Wealth is built not by reacting to every twist and turn, but by staying invested through thick and thin.”

That mindset matters. Markets rise, fall, crash, recover, and repeat — and they’ve been doing that for over a century. The investors who panic‑sell during corrections often lock in losses, while those who stay patient tend to come out stronger on the other side. When markets eventually recover (and historically, they always have), you’re not only back on track — you’re also able to buy great companies at better prices. Buffett’s other line captures this perfectly: “It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price.”

So with patience as the foundation, let’s look at the structure.

The 5 Funds in this Article (www.morningstar.com)

The Core: An “Ultimate” 3‑Fund Setup

1. VTI — Vanguard Total Stock Market ETF

This is the backbone. Instead of limiting yourself to the S&P 500, VTI gives you exposure to the entire U.S. market — large, mid, and small caps. That broader exposure can reduce concentration risk while still delivering returns that historically track very closely to the S&P 500.

Some people ask why not just use VOO, Vanguard’s S&P 500 ETF. The simple answer:

• VTI is cheaper per share
• It has a slightly higher yield
• It’s less top‑heavy
• And the overlap between VTI and VOO is a massive 87%, meaning holding both doesn’t add much diversification

Both are Morningstar Gold‑rated, but VTI’s broader reach makes it a more complete foundation.

2. SCHG — Schwab U.S. Large‑Cap Growth ETF

SCHG has quietly become a favorite among growth‑focused investors. Over the 3‑, 5‑, and 10‑year periods, it has outperformed many of its peers — and it does so with an extremely low expense ratio.

A fun detail: Schwab executed a 3‑for‑1 split in October 2024, which made the fund more accessible price‑wise without changing its underlying exposure.

If VTI gives you the whole market, SCHG tilts the portfolio toward the innovative, fast‑growing companies that have driven much of the market’s long‑term performance.

3. VIG — Vanguard Dividend Appreciation ETF

VIG focuses on companies with a long history of increasing dividends — the kind of businesses that tend to be stable, profitable, and disciplined. It includes many of the dividend names that were already on my watchlist, and it has been paying dividends since the mid‑1990s.

This fund adds a layer of quality and income to balance out the growth tilt from SCHG.

Two Complementary ETFs That Round Out the Picture

After building the core, we wanted to find ETFs that:

• Don’t overlap heavily with the three main funds
• Add exposure to different market factors
• Strengthen the portfolio in both expansions and contractions

That led us to two Invesco factor ETFs:

4. SPMO — Invesco S&P 500 Momentum ETF

Momentum tends to shine during strong market expansions. SPMO has historically outperformed the S&P 500 since its inception, and it captures the companies with the strongest price trends.

5. SPHQ — Invesco S&P 500 Quality ETF

Quality stocks — companies with strong balance sheets, consistent earnings, and high return on equity — tend to hold up better during downturns. SPHQ also has a track record of outperforming the S&P 500 over the long run.

BlackRock’s factor research (Exhibit 4, if you’ve seen it) shows this beautifully:

• Momentum thrives in expansions
• Quality shines in contractions

Together, they create a natural balance.

Why These Five Funds Work Well Together

When you combine the three core ETFs with SPMO and SPHQ, you end up with:

• Broad U.S. market exposure
• A growth tilt
• A quality tilt
• A momentum tilt
• Coverage across all 11 sectors
• Minimal overlap
• A structure that adapts to different market environments

It’s simple, diversified, and surprisingly robust.

Again, this isn’t a recommendation — just a portfolio structure we’ve personally explored and found compelling enough to share.

Conclusion

A well‑built portfolio doesn’t need to be complicated. In fact, the more moving parts you add, the harder it becomes to stay disciplined when markets get noisy. A thoughtful 3‑fund core, complemented by two factor‑based ETFs, can offer a blend of simplicity, diversification, and long‑term resilience.

At the end of the day, the most important part isn’t the exact mix — it’s the mindset. Stay patient, stay invested, and let time do the heavy lifting.
