Myth Buster· 2

Myth Buster06:17

A Fully Systematic ETF Does Not Need to Be an Index Fund

Gray recommends using an active ETF structure even when the strategy is entirely systematic. Active status can avoid third-party index costs and provide limited implementation flexibility, such as postponing a rebalance during an unusually disruptive week.

  • Systematic implementation does not require an index designation.
  • Active ETFs can avoid third-party index-agent expenses.
  • Active status permits greater flexibility around marginal implementation decisions.
  • Index deviations can create burdensome compliance and documentation requirements.

“just go active, even if your strategy is one hundred percent systematic.”

Wes Gray · 06:44

“I'll just punt to next week. That's easy in an active strategy.”

An ETF's Trading Volume Does Not Determine Its True Liquidity

Most ETFs rely on primary liquidity supplied by market makers rather than frequent trades between existing shareholders. Their bid-ask spreads and executable size therefore depend largely on the cost of acquiring or disposing of the underlying securities, not the ETF's own historical volume.

  • Only a small group of major ETFs trade mainly through abundant secondary liquidity.
  • Most ETF orders access liquidity through market makers.
  • Bid-ask spreads reflect the cost of trading the underlying basket.
  • A rarely traded ETF can still support a large trade when its holdings are highly liquid.

“The other set of ETFs, which is ninety nine point nine to nine percent of them is normal ETFs where when you go access to…”

Wes Gray · 09:51

“it just depends on the underlying basket liquidity.”

Hot Take07:35

Why Gimmicky Leveraged ETFs Fail the Grandmother Test

Gray objects to expensive, leveraged products whose swaps and embedded costs are difficult for ordinary investors to understand. His preferred products are low-fee, transparent, tax-efficient, understandable, and capable of adding long-term value.

  • Gray would not offer a product he could not recommend to family.
  • Double- and triple-leveraged products can carry opaque embedded costs.
  • Investor demand does not make a product responsible or useful.
  • Long-term value and comprehensibility matter more than novelty.

“if I'm not going to recommend this to my parents or my grandma, why do we have this in an ETF where anyone with the…”

Wes Gray · 07:52

“I like, you know, low fees, transparent, tax.”

A Straightforward ETF Can Launch in About Four Months

Wes Gray says a relatively straightforward ETF can move from a signed letter of intent to launch in approximately four months. The timeline depends on the sponsor's internal readiness, but standardized checklists and automation have compressed the operational process.

  • Four months is the typical target for a straightforward launch.
  • Internal sponsor issues can extend the process dramatically.
  • Checklists and automation reduce operational delays.

“We generally tell folks four months”

Wes Gray · 02:44

“we've got this thing so checklist and automated.”

Two Ways to Seed an ETF: Cash or Securities

An ETF can be seeded with cash contributed by investors or with an existing portfolio of eligible securities. Gray explains that Section 351 may permit qualifying property to be contributed tax-free when those securities naturally fit the ETF.

  • Cash purchases can provide initial ETF assets.
  • Eligible public securities may be contributed as property.
  • Section 351 can enable tax-free property contributions.
  • The contributed securities should naturally fit the ETF portfolio.

“cash or property is the two methods you can use.”

“you can contribute those tax free”

The Real Economics Behind ETF Startup and Break-Even Costs

Gray estimates roughly $50,000 in startup costs and around $200,000 per year in ongoing expenses for a generic ETF. Break-even assets then depend heavily on the management fee: a 1% fee may cover costs near $20 million, while a 0.20% fee may require about $100 million.

  • A generic launch may cost approximately $50,000.
  • Ongoing annual costs may be around $200,000.
  • A lower expense ratio increases required break-even assets.
  • Commercial viability depends on both pricing and assets under management.

“you're looking at a fifty k startup, soup the nuts”

Wes Gray · 05:37

“if you share one percent, your break even is twenty million. If you charge twenty basis points, which is much more marketable, your break even…”
