The ETF Story 5: The Sleeper

SPDR S&P 500, or SPY, is the world’s largest ETF today with about $240 billion in assets, but it wasn’t much to look at when it debuted in 1993. Some days it was on “volume life support,” trading as little as 18,000 shares; there was even talk of pulling the plug. Yet true believers, guerrilla m

Episode Summary

Executive Summary: The episode traces how ETFs evolved from a niche, uncertain product into a dominant investment vehicle, using SPY and Webs/iShares as key case studies. It highlights the combination of early believers, repeated education, cheap pricing, market structure, and favorable market conditions that transformed ETFs from a “flyer” into a mainstream tool for accessing broad and international exposure.

Main Topics: SPY’s rocky launch and early skepticism (Priority: 5/5): SPY debuted with fanfare in 1993 but quickly faded in trading volume, prompting doubts about whether the product would survive. Early market makers and advocates had to convince investors of its value and usability. Guerrilla marketing and product adoption (Priority: 5/5): Gary Eisenrich describes direct outreach, word-of-mouth promotion, and low fees as the main drivers of adoption. Success with small trades helped spread confidence among larger money managers. The market structure challenge: institutions and arbitrageurs (Priority: 5/5): ETF success required both investors and market makers/APs to participate. Speakers emphasize the chicken-and-egg problem: without both sides, price efficiency and liquidity would fail. Webs and the birth of the ETF concept (Priority: 4/5): Morgan Stanley’s international ETF effort, Webs, arose from client demand and custody challenges. It also introduced the term “exchange-traded funds” in its prospectus and expanded the ETF model beyond the S&P 500. Why international ETFs needed flexibility (Priority: 4/5): Unlike SPY’s UIT structure, Webs used mutual-fund-like flexibility because foreign markets posed custody, trading, and settlement problems that required latitude in execution. From institutional tool to retail brand: iShares (Priority: 5/5): After Barclays bought Webs for a nominal price, the product line became iShares and was repositioned as a broader retail brand with major marketing support and a wider investment thesis. The broader ETF shift in investing behavior (Priority: 4/5): By the early 2000s, ETFs had become recognized as transformative. Speakers note that actual use on a trading desk was often what fully convinced skeptics of their power and convenience.

Key Arguments: SPY succeeded only after initial failure because adopters needed repeated education, low fees, and a working market ecosystem. ETF adoption depended on a two-sided market: investor demand plus market makers and authorized participants willing to arbitrage and provide liquidity. Broad market conditions mattered; the 1994–95 economic upturn helped SPY become more attractive just as advocacy efforts were taking hold. Webs proved ETFs could do more than track the S&P 500 by meeting real client demand for international exposure. International investing in the mid-1990s was operationally difficult due to custody and settlement issues, making a flexible ETF wrapper valuable. iShares became successful not just through marketing, but because leaders recognized ETFs could solve long-term asset-allocation needs for retail investors. The ETF revolution was gradual: many insiders were skeptical until the products were actually used in practice and shown to work.

Data Points: SPY launch year: 1993 - First ETF discussed as the original SPY launch. SPY first-day trading volume: about 1 million shares - Eisenrich recalls heavy launch-day activity and fanfare. Early SPY trading print: 200 shares - The first print appeared on the ticker tape after launch. SPY volume after six months: 18,000 shares a day - Trading volume fell sharply after the initial launch excitement. SPY expense ratio: 25 basis points - Cited as a major selling point versus higher-cost products. SPY assets today: $270 billion - Described as the largest ETF in the series narrative. WEBS filing period: October 1993 - Bob Toll says the filing was formulated after the summer of 1993. ETF sponsor start date for Invesco QQQ: March 1999 - Ad copy notes QQQ’s role in accessing the NASDAQ 100. Estimated market environment shift: 1994-1995 - Eric Balchunas says the economy becoming favorable helped SPY grow. Time until ETF concept became widely appreciated: early 2000s - Nodig says most people did not grasp ETF impact until then. Retail brand acquisition price: $1 - Barclays Global Investors bought Webs from Morgan Stanley for a nominal amount.

Pivotal Quotes: "it just sat." — Gary Eisenrich: Describing SPY’s weak trading after a highly publicized first day. "I was enormously skeptical that second part would show up because there is a real chicken and the egg problem" — Dave Nottig: Explaining the need for both investors and liquidity providers for ETFs to function. "It wasn't until I was sitting on a trading desk and all of a sudden I could, like, hit a button and get a million-dollar exposure to the queues. I was all in." — Dave Nottig: Describing the moment ETF utility became obvious through direct use.

Implications: ETFs won by solving real market frictions—cost, access, and execution—while proving their value through repeated use. The industry’s future remains tied to innovation, distribution, and making complex exposure simple and tradable.
