The scorecard evaluates an ETF through four distinct cost channels: its published expense ratio, the tax drag created by the vehicle, the liquidity cost paid when entering or exiting, and the performance lost when the fund fails to track its index precisely. The mechanism is additive: estimate each cost in investor-relevant terms, then compare the total expected burden across funds offering equivalent exposure. This avoids treating a visible fee as the whole price while ignoring less obvious costs that may be materially larger. It also shifts due diligence toward the investor's realized outcome—what remains after ownership, trading, taxes, and implementation—rather than toward whichever provider advertises the smallest headline number.
Origin
Extracted from Masters in Business during Salim Ramji's explanation of why ETF investors should look beyond the sticker price.
Core principles
- 01Treat the expense ratio as only one component of cost
- 02Measure what the investor ultimately keeps
- 03Include transaction costs created by limited liquidity
- 04Count tracking deviation as an investor cost
- 05Prefer reliable execution over superficially cheap pricing
How to run it
- 1
Define comparable exposure
Identify ETFs tracking the same or genuinely comparable market exposure. Do not compare costs until the investment mandates are aligned.
Pro tip Check index methodology as well as the fund name.
Watch out Similar labels can conceal materially different holdings or risk exposures.
- 2
Record the headline fee
Capture each fund's expense ratio as the most visible recurring cost. Treat it as the starting point rather than the conclusion.
Watch out The cheapest expense ratio may not produce the lowest total cost.
- 3
Estimate tax drag
Assess distributions, realized gains, fund structure, and the investor's account type to estimate after-tax efficiency.
Pro tip Give tax efficiency more weight in taxable accounts.
Watch out Tax consequences vary by investor and jurisdiction.
- 4
Measure trading friction
Review liquidity, trading volume, and bid-offer spreads to estimate the cost of entering and exiting the position.
Pro tip Inspect spreads during normal and stressed markets.
Watch out A liquid underlying market does not automatically guarantee a tight ETF spread.
- 5
Review tracking quality
Compare fund returns with index returns and examine the consistency of the difference. Count persistent deviation as a cost borne by investors.
Pro tip Use multiple periods that include index rebalances and volatile markets.
Watch out A single calm-period observation can understate implementation risk.
- 6
Rank by total expected cost
Combine the recurring, tax, trading, and tracking costs, then choose the vehicle offering the best overall implementation quality.
Pro tip Document assumptions so the comparison can be refreshed later.
Watch out Do not imply false precision when future taxes or spreads are uncertain.
In the wild
An adviser compares two funds tracking the same bond index. Fund A has the lower expense ratio, but Fund B has tighter spreads, stronger tax efficiency, and more consistent tracking. After estimating the client's likely holding period and trade size, the adviser finds that Fund B should leave the client with more money despite its higher published fee.
→ The adviser selects the ETF with the lower expected total ownership cost.
A taxable investor screens several broad equity funds. Instead of sorting only by expense ratio, the investor reviews capital-gains distributions, bid-offer spreads, and long-run tracking differences. A fund that initially appeared slightly more expensive proves more efficient after taxes and implementation.
→ The investor makes an after-tax, investor-specific selection rather than a headline-fee decision.
Common mistakes
Sorting only by expense ratio
This ignores taxes, trading friction, and tracking deviation, any of which may exceed the published fee difference.
Ignoring the investor's account type
Tax efficiency matters differently in taxable and tax-advantaged accounts, so the scorecard must reflect the actual owner.
Assuming all liquidity is equal
Funds with similar holdings can have different spreads, market-making support, and behavior under stress.
Is it for you?
Best for
It is best for investors and advisers comparing multiple ETFs that provide similar market exposure.
Not ideal for
It is not ideal for judging whether the underlying asset class or investment thesis belongs in a portfolio.
From the transcript
“But beyond the sticker price, there are a number of areas that are, if anything, more important”
“the tax efficiency of the rapper becomes a really important aspect to what the investor takes home at the end of each year.”
“things like tax efficiency, things like liquidity, things like tracking are even more important financially to investors”
