ToolTip:
Why?
⭐⭐⭐⭐⭐⭐⭐⭐⭐☆
The ETF revolution is one of the greatest innovations in modern investing.
It has reduced costs.
Expanded access.
Improved liquidity.
Democratized portfolio construction.
But...
No investment vehicle—not even an ETF—can permanently override valuation mathematics.
That doesn't make today's market dangerous by definition.
It simply makes discipline more valuable than ever.
Executive Summary
Imagine standing on a beach.
Far offshore...
a massive wave begins to rise.
Some people sprint toward it carrying surfboards.
Others panic.
The smartest investors?
They quietly move to higher ground, secure their footing, and prepare.
That, in many ways, describes today's ETF market.
According to Goldman Sachs Global Banking & Markets, U.S.-listed exchange-traded funds are on pace to attract more than $2 trillion in net inflows during 2026—a staggering figure that would represent roughly a 40% increase over 2025. More than $1 trillion has already flowed into ETFs during the first half of the year, with active ETFs, thematic strategies, and model portfolios driving much of the momentum.
Those numbers are remarkable.
But they also raise an important question.
Can an extraordinary investment vehicle still produce mediocre long-term returns if the assets inside it are purchased at extraordinary valuations?
We believe the answer is...
Absolutely.
🌊 The ETF Tsunami Has Arrived
The ETF industry has evolved far beyond its humble beginnings.
Once viewed primarily as inexpensive index-tracking vehicles, ETFs have become one of Wall Street's most versatile investment tools.
Today's ETF universe includes:
📈 Active management
🤖 Artificial Intelligence themes
🪙 Digital assets
💵 Fixed income
⚖️ Buffered strategies
📊 Options overlays
🌍 International diversification
🧠 Multi-asset model portfolios
Goldman Sachs expects the number of U.S.-listed ETFs to exceed 6,000 by year-end, with active ETFs attracting more than 35% of all new ETF inflows despite representing a much smaller share of total ETF assets. Average daily ETF trading has also surged to roughly $320 billion, underscoring the growing importance of ETFs in modern markets.
This isn't merely growth.
It's a structural transformation.

⚠️ Same Valuation Mathematics🧰 The ETF Wrapper Is Brilliant
Let's be perfectly clear.
We love ETFs.
Few financial innovations have democratized investing as successfully.
They offer:
✅ Lower costs
✅ Tax efficiency
✅ Liquidity
✅ Transparency
✅ Diversification
✅ Access to markets once reserved for institutions
For millions of investors, ETFs have been nothing short of revolutionary.
But...
Here's where many investors make a subtle mistake.
They confuse the quality of the wrapper with the quality of the assets inside it.
Those are two very different things.
🎁 The Wrapper Paradox
Imagine buying an expensive gift.
Now imagine wrapping it in beautiful paper.
Has the gift changed?
Of course not.
The same logic applies to investing.
An ETF is simply a wrapper.
A remarkably efficient wrapper.
But still...
a wrapper.
Putting an expensive stock inside an ETF doesn't suddenly make it inexpensive.
Likewise...
placing an overvalued market inside a tax-efficient structure doesn't magically create a margin of safety.
That's why we believe one simple principle deserves repeating:
A cheaper wrapper never makes an expensive asset cheap.™
🐘 The Elephant in the Trading Room
While investors celebrate record ETF inflows...
another statistic deserves equal attention.
The S&P 500 currently trades around 29.7 times trailing earnings.
For perspective:
| Metric | Value |
|---|---|
| Current Trailing P/E | 29.71x |
| Historical Mean | 16.23x |
| Historical Median | 15.08x |
In other words...
today's U.S. stock market trades at roughly twice its long-term historical average on this measure.
Does that mean investors should panic?
No.
Does it mean every stock is overpriced?
Certainly not.
Does it suggest investors should become more selective?
Absolutely.
📐 Why Valuation Still Matters
Markets can remain expensive for surprisingly long periods.
Sometimes years.
Occasionally even longer.
History reminds us, however, that valuations eventually matter.
Buying wonderful businesses at reasonable prices has historically produced better long-term outcomes than paying any price simply because everyone else is buying.
That's particularly relevant today.
Record ETF inflows tell us investors are enthusiastic.
They do not automatically tell us that every underlying asset represents good value.
Those are entirely separate questions.
🌍 More Choice Is Wonderful
One of the genuinely positive developments highlighted by Goldman Sachs is the explosion in investor choice.
Need exposure to:
🌎 Emerging markets?
⚡ Artificial Intelligence?
🏦 Banks?
🧬 Biotechnology?
🛰️ Space?
🥇 Gold?
💵 Treasury Bills?
There's almost certainly an ETF for it.
In many cases...
multiple ETFs.
That's progress.
Competition lowers costs.
Innovation expands opportunity.
The ETF revolution has unquestionably improved access to financial markets.
The key, however, is remembering that access and valuation are not synonyms.
🎭 A Dash of Market Humor
😂 Wall Street has become so creative...
there are now nearly enough ETFs to build an ETF that owns other ETFs...
which themselves own single-stock ETFs...
that eventually own the same handful of companies.
We're only half joking.
🚗 Buying an expensive index simply because it's wrapped inside a shiny ETF is a little like paying double sticker price for a car because the dealership upgraded the floor mats.
Nice mats.
Still expensive.
🏄 And remember...
When a tsunami approaches...
everyone notices the wave.
Experienced surfers pay attention to the current underneath.
