Looking at the linked article: Best ETFs For Investors 2018
The table has a footnote:
Cumulative cost of holding a $10,000 position for a decade.
Incorporates annual expense ratio, bid/ask spreads and cost offset
from securities lending.
That leads to an interesting paragraph later on:
Who’s got the cheapest ETF covering the whole U.S. stock market? The
iShares family from BlackRock wins this prize, with a fund (ticker:
ITOT) that, over the course of a decade, will chip only $6 out of a
$10,000 investment. For inflation-protected bonds, Schwab is the
place to go, with an $85 cost over ten years for its TIPS fund (SCHP).
In small foreign stocks, Vanguard stands out. It has an index fund
(VSS) that is so efficient the cost is negative.
In fact in the table with the footnote there is a fund with a negative cumulative cost.
following the links to the Best ETFs: The Honor Roll
The category for mid- and small-cap foreign stocks is another one with
eye-opening differences. Honor Roll member Vanguard FTSE All-World
ex-U.S. Small Cap (VSS) has a cost of -$223 and Schwab International
Small-Cap Equity (SCHC) is listed here with $20. The category laggard,
from Hartford, will run you $673.
Now back to the first page: Best ETFs For Investors 2018
Our cost formula has three elements. One is the expense ratio reported
in the fund’s prospectus. Next is the bid/ask spread maintained by
market makers in the ETF. The third item is something you won’t find
in other ETF ratings: the cost offset that the fund manager delivers
to you by lending securities to short-sellers.
Securities lending is a big business, yielding $777 million a year to
investors in Best ETFs. In a portfolio of small-company, foreign or
speculative shares, it can exceed the expense ratio. That’s how
Vanguard FTSE All-World ex-U.S. Small-Cap (VSS) wound up with a
ten-year holding cost of -$223 per $10,000 invested.
