Eric Balchunas – The Past, Present & Future of ETFs - [Invest Like the Best, EP.93]

In plain words

This piece breaks down ETFs (exchange-traded funds, like stocks that hold a basket of investments). Eric Balchunas says the market is split: dirt-cheap index funds (e.g., VTI at 0.04% fees) and flashy theme funds (like ARK). He likes VTI as the 'perfect ETF,' is neutral-positive on ARK (active stock-picking, up 70% last year), and warns GBTC (Bitcoin trust) has poor structure with 50-100% premium (price above actual value).

Eric Balchunas – The Past, Present, and Future of ETFs

At a Glance

Eric Balchunas (Senior ETF Analyst at Bloomberg Intelligence) engages in an in-depth discussion with Patrick O'Shaughnessy on the structural advantages, market landscape, and future trends of ETFs. Balchunas’s core thesis is that the ETF market has formed a binary structure of "ultra-low cost" and "shiny new things," with 99% of capital inflows concentrated at these two extremes, while products in the middle ground are dying out.


1. ETF Market Landscape: A Binary World of Ultra-Low Fees and Shiny New Things

Eric Balchunas argues that the ETF market should not be divided by asset class, but rather into two categories: "ultra-low fee" and "shiny new things."

  • Ultra-low fee products: Approximately 90% of fund inflows go to products with expense ratios of 20 basis points or less, nearly all from the duopoly of Vanguard and BlackRock. Balchunas calls this the "great cost migration."
  • Shiny new things: The remaining funds flow into high-yield thematic products (e.g., robotics ETFs, ARK funds). Balchunas notes that even if these products decline in the future, only about half of the funds will withdraw—"I'm convinced people forgot they bought it because they chased the rally."

Key data: A chart released by Balchunas shows that the number of indices has surpassed the number of stocks, exhibiting a "hockey stick" growth pattern. However, he cautions: "No one points out that the number of mutual funds (about 7,000) is still greater than the number of indices."


2. Active Management ETFs: Oxygen Stolen by "Smart Beta"

Balchunas believes the actual scale of active management ETFs is underestimated—if smart beta is counted as active, the share of active strategies in ETF assets has reached 20% (approximately $700 billion).

  • The essence of smart beta: Balchunas points out that "designing an index is the new active management." Giants such as Goldman Sachs, Fidelity, and JPMorgan are packaging their "secret recipes" into indices, achieving self-built indexation.
  • The plight of pure active ETFs: Currently, there are about 125 active management ETFs, accounting for only 1% of total ETF assets. The reason is that smart beta "has sucked away the oxygen that active management hoped to obtain."
  • Key variables for evaluating new ETFs: Balchunas looks at: raw exposure (how high the active share is), correlation with the broad market, standard deviation, and index weighting method. He specifically notes that "equal weighting is a legal stimulant"—it artificially amplifies volatility, making the strategy appear effective when the size factor performs well.

Regarding ARK funds: Balchunas believes Cathy Wood got one thing right—she realized that companies like Amazon, Tesla, and Google are difficult to classify into a single industry, so she "directly broke industry boundaries and only selected innovation." ARK's active share is about 95%, with a fee of 75 basis points, and "no one minds because she achieved a 70% return last year."


3. Tax Advantages and Potential Regulatory Risks of ETFs

Balchunas provides a detailed explanation of the source of ETFs' tax advantages—the creation/redemption mechanism—and describes it as the ETF's "flux capacitor."

  • Mechanism Principle: The ETF creation/redemption process essentially applies the "warehouse receipt" concept to stocks and bonds—exchanging SPY shares (receipts) for 500 stocks (underlying assets) without triggering a taxable event. Balchunas calls this a "happy accident."
  • Magnitude of Tax Advantage: Morningstar research shows that ETF capital gains distributions are nearly zero (rounded to 0%). Balchunas emphasizes: "This single feature alone is enough to drive investors out of other structures."
  • Regulatory Risk: Balchunas acknowledges concerns—"Governments are very good at finding potential taxable cash pools." However, he believes that because ETF issuers (such as ICI) also lobby, and mutual funds should likewise be reformed (investors should not be taxed due to others' redemptions), the likelihood of a change in tax treatment in the short term is low.

4. Behavioral Risk: The ETF's Biggest Enemy Is the Investor Themselves

Balchunas argues that the greatest risk of ETFs is not the structure itself, but their tendency to "tempt investors into trading."

  • John Bogle's criticism: ETFs tempt you to trade, and trading erodes all cost advantages. A German study found that investors underperform in ETFs compared to mutual funds because they trade ETFs more frequently.
  • The double-edged sword of liquidity: Intraday liquidity in ETFs is a major advantage for institutions (e.g., Bridgewater holds large positions in IEMG), but it can be harmful for retail investors.
  • "The Art of Doing Nothing": Balchunas proposes a future book concept—teaching investors how to "do nothing." He believes this is the next stage of investor enlightenment: "You already have low costs and good structure; the next step is not to mess it up yourself."

Key data: In 2008, Vanguard saw continuous monthly inflows—even when the market dropped 17% in October. Balchunas remarked: "They trained their investors to be as disciplined as Navy SEALs."


V. Future Trends: Alternative Investment ETFs, Fixed Income Factors, and the ESG Dilemma

Balchunas believes that alternative investment ETFs represent the biggest opportunity "waiting for a catalyst."

  • Potential of Alternative ETFs: Currently, alternative ETFs hold only about $2 billion, compared to approximately $200 billion in similar mutual funds. JPMorgan has explicitly stated its intention to "democratize hedge funds." Balchunas specifically notes that if AQR converts its market-neutral mutual fund into an ETF, "it could cause this category to explode."
  • Fixed Income Factor ETFs: Balchunas considers this an "underrated but potentially big" area. Cliff Asness has already launched factor-based bond funds, and BlackRock is also positioning itself. However, the challenge lies in the fact that bond factor ETFs are harder to describe, have less academic research backing, and lack "catchy terminology."
  • The ESG ETF Paradox: Balchunas observes that the "ratio of positive media attention to fund inflows" for ESG is the widest among all categories—"ESG gets the best coverage, but no one actually buys it." He compares this to the polling bias during Trump's campaign, where people are ashamed to admit they do not support it, but their actions do not follow through.

On Bitcoin ETFs: Balchunas explicitly states he is "very bullish on Bitcoin ETFs." He argues that the ETF structure offers investors the best protection, even with a 1-2% premium (far better than GBTC's 50-100% premium). "If you wait until Bitcoin is perfect before approving it, then it might no longer make sense—because by then you could just buy Bitcoin directly."


6. Market Downturn and the ETF "Perfect Storm"

Balchunas believes the next bear market could become a turning point for passive investing to gain significant market share.

  • The "Triple Blow" to Active Management: Market declines lead to asset shrinkage (a one-third reduction in revenue) + panic redemptions by investors + investors using the downturn to optimize capital gains taxes (previously reluctant to sell due to unrealized gains). Balchunas predicts passive share could rise from 35% to 50%.
  • Active Equity vs. Active Bonds: Over the past four years, active equity mutual funds have seen outflows of approximately $1 trillion, while active bond mutual funds have actually seen inflows of about $70 billion. Balchunas believes advisors think "bonds are harder, and bond managers are more valuable."
  • ETFs Are Not the Source of Price Distortion: Balchunas points out that ETFs hold only about 7% of the stock market, with total passive investing at roughly 16-17%. He argues that the S&P 500 index itself may be more "bubble-like"—25% of ETF inflows go into S&P 500 ETFs, and a large number of active managers are also "embracing" the index.

Judgments Worth Remembering

1. The ETF market is a binary world of "ultra-low fees" and "shiny new things" (Balchunas): Approximately 90% of fund inflows go to products with expense ratios ≤20 basis points, while the remainder flows into high-yield thematic products. The middle ground is disappearing.

2. Smart beta is the new active management (Balchunas): "Designing an index is the new active management." Goldman, JPMorgan, Fidelity, and others are packaging "secret recipes" into indices. If smart beta is counted as active, active strategy assets in ETFs have already reached 20%.

3. Equal weighting is a "legal stimulant" (Balchunas): Many thematic ETFs adopt equal weighting, which artificially amplifies volatility and makes the strategy appear effective when the size factor performs well. Investors should be aware of this.

4. The tax advantage of ETFs is a "windfall" (Balchunas): The creation/redemption mechanism essentially applies the concept of "warehouse receipts" to stocks and bonds, without triggering taxable events. Morningstar research shows ETF capital gains distributions are nearly zero.

5. The biggest enemy of ETFs is investors themselves (Balchunas): A German study found that ETF investors underperform mutual fund investors because they trade ETFs more frequently. Balchunas proposes "the art of doing nothing" as the next stage of investor enlightenment.

6. Alternative ETFs are the biggest opportunity "waiting for a catalyst" (Balchunas): Alternative ETFs have only $2 billion in assets, while comparable mutual funds have approximately $200 billion. If AQR or Vanguard launches a market-neutral ETF, it could cause this category to explode.

7. The next bear market could push passive share from 35% to 50% (Balchunas): Active management funds will face a triple blow of asset shrinkage, panic redemptions, and tax optimization. In 2008, only about one-third of active managers outperformed the market.

8. ESG ETFs have the biggest paradox of "positive attention versus fund inflows" (Balchunas): ESG receives the best media coverage and the broadest institutional endorsements, yet fund inflows are minimal. He compares it to the polling bias during Trump's campaign.
