Passive investing tracks a market index rather than tries to beat it, and it now makes up nearly 60 percent of the US equity fund market. For advisors and RIAs, this affects how you price your services, build client portfolios, and manage tax exposure.
Low costs are the main benefit, but the decisions lie in which index you pick, how you blend strategies, and where active earns its fee. This guide breaks down the key terms and concepts and shows how they apply to your practice.
Passive investing is a long-term strategy that aims to match a market index or rules-based benchmark, not beat it. It often uses index mutual funds and index ETFs that hold the same securities in the same weights as the chosen benchmark. These funds follow clear rules and trade infrequently. They also keep turnover low, which helps keep costs and taxes down in client portfolios.
For advisors and RIAs, it helps to separate the passive investing strategy from the vehicles you use. Index funds and ETFs can support a passive investing approach, but you can still trade an ETF actively, time entries, or tilt around benchmarks. In most advisory practices, passive investing means using these index vehicles in a systematic way as the core of a client’s allocation.

Active investing relies on security selection, market timing, or factor tilts driven by a manager’s views. The goal is to beat a benchmark, not just track it. This takes more research, trading, and hands-on portfolio management than a passive approach.
The two strategies differ most in costs, turnover, and tax impact:
| Passive investing | Active investing | |
|---|---|---|
| Goal | Match a benchmark | Beat a benchmark |
| Typical expense ratio | 0.2% or less | 1.25% to 1.5% |
| Portfolio turnover | Low | High |
| Tax efficiency | Higher (fewer taxable events) | Lower (more short-term gains) |
| Best suited for | Large-cap, efficient markets | Less efficient markets, specific client mandates |
In large-cap US equities, just 7 percent of active funds survived and beat their passive peers over the past decade. But in less researched segments, such as small-cap stocks or emerging markets, skilled active managers add value. Active investing can also make sense when clients have specific goals, like ESG screens or concentrated stock management.
Most advisory practices today don’t choose between active and passive investing. They use both. A common model uses passive index funds as core holdings and allocates a smaller portion to active strategies in less efficient areas. This keeps overall costs low while still leaving room for targeted decisions that a rules-based index simply can’t make.

Passive investing works through several vehicles, each with its own structure, cost profile, and role in a client portfolio. Knowing how each one works helps you pick the right tool for each situation.
An index fund is a mutual fund that holds the same securities as a chosen benchmark in the same weights. It prices once a day after the market closes. This makes it a straightforward choice for retirement accounts and long-term allocations.
ETFs also track an index but trade on an exchange throughout the day, just like stocks. They are often cheaper than index funds and give advisors flexibility to trade intraday, target specific sectors, and access international markets.
A benchmark is a standard index, such as the S&P 500 or Russell 2000, that a fund is designed to track. Indices can be market-cap weighted, equal-weighted, or built around other rules. Each choice affects how a client portfolio behaves.
Smart beta funds follow rules-based strategies that target specific factors, including value, size, quality, and momentum, rather than just weighting by market cap. They sit between pure index tracking and active management. Some advisors use them as satellite holdings in a broader passive portfolio.
Direct indexing means owning the individual stocks in an index directly, rather than through a fund. This gives advisors the ability to customize holdings for tax-loss harvesting, ESG screens, or concentrated stock positions.
Each of these vehicles fits a different part of the portfolio construction process. Most advisors use more than one. The right mix depends on your client’s tax situation, account type, and investment goals.

For advisors and RIAs, the benefits of passive investing go beyond lower fund fees. They also impact how you price your services, scale your practice, and guide clients through market volatility. Here are some of the pros of passive investing:
Passive funds typically charge around 0.2 percent, versus 1.5 percent for many active funds. This cost difference is easy to show clients. Lower product fees give you room to price your advisory fee clearly, without making the total cost look excessive. This makes fee conversations more straightforward and supports your value for money case with prospects.
Across most major asset classes, the data favors passive strategies over active management after fees, especially over longer time horizons. Morningstar’s Active/Passive Barometer and S&P’s SPIVA scorecards both point in the same direction: most active managers don’t outperform their benchmarks net of fees. This gives advisors a data-backed case for using passive funds as core portfolio holdings.
Passive index funds and ETFs are easy to implement at scale, which matters when you manage dozens or hundreds of client accounts. Model portfolios built on passive vehicles reduce the time you spend on security selection and monitoring. This frees you to focus on financial planning, tax work, and client communication.
Passive investing follows rules-based benchmarks, which makes it easier to explain your investment process to clients. A defined strategy with a visible benchmark gives clients context when markets drop. It also helps them stay invested rather than react.
FINRA notes that passive strategies can help investors avoid emotional decisions like panic selling or chasing recent winners.
Together, these benefits make your practice easier to run and grow. Passive investing lowers costs for clients and gives you a concrete way to explain the value you deliver.

Passive investing limits costs and simplifies portfolio management, but it doesn’t eliminate risk. Knowing the trade-offs helps you apply passive tools in the right places in client portfolios. Here’s what you need to watch out for:
Passive investing gives clients market-level exposure. This means they absorb the full weight of any broad market decline. Research shows that stocks with heavy passive ownership tend to have higher betas and greater sensitivity to market-wide moves.
Passive strategies also carry factor-level risk: a market-cap weighted index tilts toward the largest, most expensive stocks in the index.
Major indices like the S&P 500 can become heavily weighted toward a handful of large-cap stocks and concentrate risk rather than spread it. From 2010 to mid-2023, about 25 percent of the Russell 2000 consisted of stocks from the Russell 3000’s largest 1,000. This mix can blur the small-cap label.
ETFs that track niche indices or less liquid asset classes can carry wide bid-ask spreads and thin trading volumes that offset their low expense ratios. These ETFs can be hard to exit at a fair price in stressed markets, since you need a buyer on the other side of every trade.
Picking the wrong index for a client’s goals can be just as costly as picking the wrong active manager. A broad market index may not align with a client’s income needs, risk tolerance, or time horizon. Passive funds follow the rules of their chosen index, with no manager to adjust course when the fit breaks down.
Passive investing works well in most client portfolios, even with these limitations. The key is matching the right index vehicle to the right account, objective, and client profile.
Most advisors don’t use passive investing as an all-or-nothing approach. They build around a core of low-cost index vehicles and add active exposure where it makes sense. The combination depends on the client’s account type, tax situation, and goals. Three portfolio models are most common in advisory practices:
Passive tools fit into almost every advisory business model. Fee-only RIAs use them to build low-cost scalable model portfolios. Hybrid firms and TAMP users often access pre-built passive or blended model portfolios through their platforms. But across these models, passive investing doesn’t remove the need for advisor skill. These are the areas where your judgment still drives outcomes:
Passive investing has changed how advisors build and scale their practices, but it hasn’t changed what clients need. The advisor’s job is to make the decisions passive funds can’t: which index to hold, in which account, and for which client.
