The rule screens ETFs using two primary inputs: cost and issuer trust. First, find funds that deliver the desired exposure and compare their annual expense ratios. A fee below five basis points is treated as effectively negligible because the difference between nearby ultra-low fees has little practical impact. Next, assess the issuer's brand and credibility, since investors may reasonably prefer an established provider over an unfamiliar company offering a nominally free product. The output is not necessarily the absolute cheapest ETF, but a very inexpensive fund from a trusted provider. This prevents false precision: investors retain the substantial compounding benefit of low costs without taking unnecessary product or issuer risk to save one or two additional basis points.
Origin
Extracted from Masters in Business during Eric Balchunas's explanation of ETF fee competition, adviser selection criteria, and why trusted brands continue attracting assets even when unfamiliar issuers offer zero-fee products.
Core principles
- 01Fees compound against investors over time.
- 02A fee below five basis points is already effectively negligible.
- 03Trusted fund brands reduce operational and product-quality uncertainty.
- 04Zero cost is not automatically better than very low cost.
- 05Avoid sacrificing trust merely to save one or two basis points.
How to run it
- 1
Define the required exposure
Specify the index, asset class, market, or strategy the ETF must provide. Compare only funds that satisfy substantially the same investment objective.
Pro tip Confirm that similarly named funds actually hold comparable portfolios.
Watch out A lower fee cannot compensate for choosing the wrong exposure.
- 2
Screen for very low fees
Convert expense ratios into basis points and identify funds near or below the five-basis-point threshold. Eliminate meaningfully more expensive options unless they provide a relevant additional benefit.
Pro tip Remember that three basis points costs roughly three dollars annually per $10,000 invested.
Watch out Do not confuse a small-looking percentage with an insignificant long-term cost when the fee is well above the threshold.

Evaluate issuer trust
Review whether the provider is an established fund issuer with a credible operational history. Use brand confidence as a practical second filter after cost.
Pro tip Look for evidence of scale, durable operations, and experience managing comparable funds.
Watch out An unfamiliar zero-fee product may use price as a gimmick without providing equal confidence.
- 4
Stop optimizing trivial differences
Once several trusted funds fall below five basis points, choose based on relevant secondary factors rather than chasing the final one or two basis points. These may include liquidity, tracking, tax treatment, or brokerage compatibility.
Pro tip Document why the selected fund is good enough so minor future fee changes do not trigger needless switching.
Watch out Frequent switching can introduce taxes, spreads, and behavioral mistakes that outweigh tiny fee savings.
In the wild
An investor compares two broad-market ETFs with nearly identical holdings. One charges three basis points from a lesser-known issuer, while the other charges four from a large established provider. Applying the rule, the investor recognizes that both are already below five basis points and selects the trusted provider rather than optimizing a one-basis-point difference.
→ The investor obtains the desired exposure at an effectively negligible cost without accepting unnecessary issuer uncertainty.
A zero-fee ETF competes with a three-basis-point ETF from an established issuer. The investor checks the annual difference, finds it immaterial for the portfolio size, and chooses the established fund after considering trust, liquidity, and product durability.
→ The decision prioritizes a robust long-term holding over a potentially gimmicky headline price.
Common mistakes
Treating zero as categorically superior
A zero-fee label can dominate attention even when the economic difference from three or four basis points is trivial. Cost should be evaluated alongside issuer trust and product quality.
Ignoring differences in exposure
Investors may compare expense ratios before confirming that the funds hold equivalent assets. The investment objective must be matched before applying the fee threshold.
Over-optimizing one basis point
Constantly switching between ultra-low-cost funds can create more friction than the tiny fee reduction saves. Once the threshold is met, focus on material secondary factors.
Is it for you?
Best for
It is best for long-term investors comparing broadly similar low-cost ETFs from multiple issuers.
Not ideal for
It is not sufficient when funds differ materially in liquidity, tracking quality, tax treatment, holdings, or investment strategy.
From the transcript
“I think once you get below five you're good.”
“the two most important criteria for them in picking an ETF. Number one is fee. Number two is brand.”
“it's the low fee plus the brand that is almost like an irresistible value proposition for most people.”
