Wall Street was fascinated by the initial public offering (IPO) of Space Exploration Technologies (NASDAQ: SPCX). Not only was it huge, raising $75 billion from investors (nearly $86 billion if you include the underwriters’ overallotment), but the business seems to come straight out of a science fiction novel. According to Jeremy Grantham, that IPO could be a sign that the AI-driven rally is about to break.
Who is Jeremy Grantham?
Jeremy Grantham is the co-founder of investment firm GMO. However, his real claim to fame is that he publicly called the top of the Dot-com bubble. The market decline following that top was long and painful, with the Nasdaq dropping nearly 80% over several years. It took about 15 years for the Nadaq to regain all the ground it had lost. When Grantham is worried about a market bubble, there’s a good reason to listen.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same “Total Conviction” signal is flashing for a company 1/100th the size of Nvidia. Continue »
He recently warned that the market is the most expensive in history during an interview with CNBC. The big story is the massive investment in artificial intelligence (AI), which is driving up AI stocks. That’s similar to the overzealous investment in the internet at the turn of the century. And while SpaceX isn’t technically an AI stock, it is investing in AI, and CEO Elon Musk has pitched the idea of building AI data centers in space. Grantham sees the massive IPO as another sign of a potential top, noting that internet stock IPOs were similarly big news toward the end of the 1990s.
Grantham is probably right, but what should you do about it?
The interesting thing about bear-market predictions is that they are wrong until they suddenly become correct. Bears can be wrong for a long time before quickly looking prescient, with Grantham admitting that the timing of the top he foresees is uncertain. So what is an investor to do? The quick answer is don’t panic and sell everything you own, becoming a de facto market timer.
History is very clear. If you bought an S&P 500 Index (SNPINDEX: ^GSPC) fund, like SPDR S&P 500 ETF (NYSEMKT: SPY) or Vanguard S&P 500 ETF (NYSEMKT: VOO), or even the Nasdaq Composite index and simply held tight through the Dot-com crash, you would have eventually seen your investment recover and then go on to new highs. Even the Great Recession wasn’t enough to stop the broader indexes from continuing their long-term upward climb.
