ETF Rising Stars

While the very largest ETFs attract the bulk of flows, a few smaller products manage to beat the odds and emerge from obscurity each year to capture investors' imagination and assets. Over the past year, growth in robotics, the Internet and China have led to outsized investments into smaller ET

Episode Summary

Executive Summary: The episode examines how ETF “rising stars” emerge from obscurity to become major products, using Eric Balchunas’s asset-growth screening framework and music/radio metaphors. The hosts and guest Carolina Wilson highlight current winners like BOTS, ARKW, EMQQ, KBA, and potential future breakouts such as PAVE, KWEB, BAR/COMB, JETS, MJX, and LIT, while stressing that performance, story, fees, and portfolio role determine whether these funds stick.

Main Topics: ETF market tiers and the 'rising star' framework (Priority: 5/5): Balchunas divides ETFs into oblivion, middle class, and elite tiers based on assets, then looks for products that jump from small bases into billion-dollar territory. Music metaphors for product discovery (Priority: 4/5): The discussion uses WLIR's 'Screamer of the Week' and indie/new-wave analogies to describe how ETF watchers identify early breakout themes before they become mainstream. Historical validation of the screening method (Priority: 5/5): The hosts review past picks like MTUM, TOTL, NOBL, and FXU to show which products became winners, which stalled, and how asset growth can be misleading without durable demand. Current rising stars in ETFs (Priority: 5/5): The episode spotlights BOTS, ARKW, EMQQ, and KBA as present-day high-growth funds driven by robotics/AI, innovation themes, China internet exposure, and China A-shares inclusion. How theme ETFs fit in portfolios (Priority: 4/5): Theme and factor ETFs are framed as 'hot sauce' or garnish: small, high-conviction allocations that can add upside but require accepting volatility and potential underperformance. Future candidates and market catalysts (Priority: 4/5): The panel looks ahead to funds tied to infrastructure, Chinese internet, commodities, airlines, cannabis, and lithium/electric vehicles, suggesting future inflows will depend on macro trends and policy.

Key Arguments: ETF success is not just about performance; a product must also have a compelling narrative, low overlap with broad indexes, and enough assets to become durable. Many ETFs live in 'oblivion' with under $50 million in assets, and moving from that category to the billion-dollar 'elite' class is extremely difficult. Shiny-object performance bursts often attract assets quickly, as seen in robotics, AI, and innovation funds, but those gains can reverse if the underlying story fades. Theme ETFs should be used in small sizes because they are often concentrated, more volatile, and can underperform broad market benchmarks. A product can gain traction by filling a gap left by larger funds, such as China internet exposure in EMQQ or inexpensive commodities exposure in BAR and COMB. Lower fees and greater liquidity can help a late entrant take share from an existing ETF, as seen in BOTS versus ROBO. Some funds grow due to a narrow institutional use case rather than broad retail adoption, as illustrated by FXU's decline after losing a major fund-of-funds allocation. The future of ETF growth is likely tied to structural trends like infrastructure spending, China market opening, EV battery demand, and cannabis legalization.

MJX assets: $400 million - Alternative Harvest ETF discussed as a potential cannabis play. LIT assets: Nearing $1 billion - Global X Lithium & Battery Technology ETF.

Pivotal Quotes: "42% of them have less than $50 million. So I would consider that oblivion." — Eric Balchunas: Explaining the ETF asset-size tiers and how many products remain too small to matter. "If you can not just beat the SP by a couple percentage points, but if you can crush it into oblivion... you will get assets." — Eric Balchunas: Describing why strong performance is often the catalyst for ETF inflows. "I would say that given that it does have little overlap, which we call high active share, it should be used like hot sauce." — Eric Balchunas: Advising listeners to use thematic ETFs in small, complementary allocations.

Implications: ETF winners are increasingly theme-driven, fee-sensitive, and story-led. For investors, the lesson is to keep broad-core allocations boring and cheap, and use these high-conviction ETFs sparingly as satellite bets on megatrends.
