June has officially arrived, which means a lot of kids are starting camp, vacations are on the horizon, and Q2 estimated tax payments are due next week. Another big theme in markets taking place right now is the highly anticipated “big three” upcoming IPOs. In light of this historic wave of IPOs, I wanted to share a few considerations for investors and how I’m approaching this with my clients.
SpaceX plans to make its public debut on Friday at a valuation of $1.75 trillion. The company plans to raise $75 billion, making it the largest IPO in history. Along with being the largest IPO, it has also been the most highly debated initial public offering that I’ve encountered in my career. I’ve been asked “how do I get access to this stock?” and had just as many conversations asking “how do I avoid this stock?”
In addition, Anthropic and OpenAI have both expressed their plans to go public later this year, each targeting valuations exceeding $1 trillion. Three IPOs above $1 trillion valuations alone is unprecedented, not to mention the fact that all three of these could occur within a 6-12 month period. There are a lot of opinions about what these IPOs mean for the broader stock market. On the positive side, these are three of the fastest growing companies that most investors have never had access to before. By going public, investors can now have exposure to three companies that are on the frontier of innovation. On the flip side, these companies are spending a lot of capital, none are currently profitable, and all have much higher valuations relative to the revenues they generate compared to other public tech companies.
With the SpaceX IPO in particular, another topic that has gotten a lot of attention is how quickly the stock will be included in popular indexes. Historically, most of the popular indexes (i.e. Nasdaq-100, S&P 500, etc.) had restrictions regarding company profitability, the number of shares available to trade, and the length of time following the initial listing before a company was eligible to be included in the index. Following the news of the SpaceX IPO, multiple indexes including the Nasdaq-100 (QQQ is a popular ETF that tracks this index), changed their rules to accelerate the timeline for when companies will be added to the index. SpaceX will be eligible to be included within the Nasdaq-100 after just 15 trading days.
POs often experience an initial “pop”, with the average return being 19% on the first day of trading on public markets. Intuitively this makes sense. Companies want to generate positive media coverage and create a buzz around their brand. Additionally, the general public has previously not had access to invest in these companies and so there’s a lot of excitement and demand to buy these shares. However, after the initial hype begins to fade, most companies have underperformed the broader stock market over the next three years following their public debut. SpaceX’s IPO was oversubscribed by institutional investors and so I expect the stock to have a strong initial debut. The concern with fast track index inclusion is that all the people who own index funds are buying the initial “pop”. If the stock doesn’t live up to the high expectations and the price falls over the months and years ahead, index fund owners are the ones who bear the brunt of these poor returns.
I’m not going to get into whether the fast-track index inclusion is the “right” or “wrong” decision, but I do want to share how I’m thinking about this change of rules and the potential implications it could have on your investments.
I’ll start by sharing an analogy that I think helps explain some of the potential challenges of index funds needing to buy SpaceX stock. Imagine that Taylor Swift releases a new album and announces she’s going on tour this summer (I know there are at least a few “Swifties” reading this newsletter). You’re determined to see her perform this new album so you begin to look up concert tickets. You have a specific date in mind that you’d like to attend the concert. Also, you want to see her perform at a particular venue, on the lower level, and want your three best friends to join you for the concert. You start your search and quickly realize that finding four seats in a row, at your preferred venue, on your ideal date doesn’t exist (or is ridiculously expensive). Why do I share this analogy? Because all of these criteria are “constraints” which limit your ability to find what you’re looking for at a reasonable price.
The same concept applies to investing. The responsibility of an index fund manager is to mimic the composition and the performance of the index that it tracks. This means that when a new company comes into the index, the manager is forced to buy shares of this stock based on its proportional weight within the index. This constraint can be problematic for a few reasons.
Forced Liquidity – The cash to buy shares of the new company needs to come from somewhere. This typically means the fund manager is selling other stocks to generate the liquidity to buy this new entrant to the index. If SpaceX enters the index as one of the top ten largest companies, this could put downward pressure on other large stocks.
Supply & Demand Imbalance – A very limited amount of all SpaceX shares will be eligible to trade within the first few months due to restrictions on current & former employees selling shares. If index fund managers are forced to buy SpaceX shares, this creates new demand for these shares. When there is high demand and limited supply of a stock, this typically forces a stock price higher.
Post Lock-Up Liquidity – Over the six month period following the IPO, SpaceX employees will be eligible to sell their shares. This creates an increased total amount of shares eligible for trading. As mentioned above, one concern is that investors who own index funds may be paying a higher price for SpaceX stock because the portfolio manager is forced to buy the stock earlier than before. Once employees are eligible to sell their shares, this new wave of supply could cause the stock price to drop at the cost of index fund investors.
Will things play out this way? My honest answer is, I don’t know. Anyone who says differently is sharing their opinion because we’ve never had a company IPO at this valuation and the index fund providers just recently changed their rules.
So what am I doing about this and how do I approach positioning investment portfolios?
First, this is one of the primary reasons that I don’t invest in index funds. The two main ETF providers that I use, Dimensional and Avantis, both take a flexible approach to trading and rebalancing that isn’t subject to the same constraints that index fund managers are. Additionally, they screen companies based on their profitability and valuation before determining how much of a specific company to own within their funds. Another option to customize which stocks you own or to exclude specific companies is by owning stocks outright through direct indexing.
I’m hopeful it’s a strong debut for SpaceX this week and beyond. If this post triggered any questions or you want to further discuss your investment strategy, I welcome the opportunity to chat with you about your personal situation.
