The AI Bubble: A Potential Wealth Wrecker?
In the world of investing, a looming question hangs over the US market: is the AI bubble about to burst? This is a dilemma that has investors on edge, especially given the success stories of AI in the world's largest economy.
The fear of a significant correction has prompted a sell-off of tech stocks, with investors concerned about sky-high valuations and the massive costs associated with data centers and chips. Last week, the US tech markets experienced a wild ride, with a brief boom followed by a sharp decline.
The Boom and Bust Cycle
Nvidia's better-than-expected results temporarily boosted the markets, with its share price climbing over 5% on Thursday. However, by the end of the day, the Nasdaq Composite closed 2.2% lower, and the S&P 500 dropped 1.6%. Investors struggled to shake off their apprehension about overvalued companies.
Laith Khalaf from AJ Bell Investment Service puts it bluntly: "Talk of a stock market bubble is everywhere, and for good reason. US stock market valuations are through the roof, and the tech giants are venturing into an unpredictable AI future, burning through billions of shareholder dollars."
Global Impact of a US Tech Correction
The fallout from a US tech correction would be felt worldwide. The sector's outstanding performance means it now makes up a significant portion of US and global tracker funds, which are likely to be a substantial part of investor portfolios due to their success.
Many investors may not realize their exposure to an AI bubble through ready-made tracker funds in their personal pensions, ISAs, and even workplace pensions. The AI boom's star players are concentrated in a few mega-stocks, which dominate the typical retail investor's portfolio.
Jason Hollands from Evelyn Partners, a wealth management firm, highlights that the "Magnificent Seven" tech stocks, including Nvidia, Alphabet, Amazon, and Broadcom, make up over 37% of the S&P 500's market value and 26% of the MSCI World Index. He adds that passive investing, which replicates an index at low cost, has become a significant investment strategy, further compounding exposure to these companies.
The Role of Passive Investing
Hollands explains that the typical UK workplace pension scheme has 60-80% invested in equities closely aligned with global indices, with 65-75% linked to the US market. This means the AI-linked goliaths are a substantial part of these investments. For example, Nvidia's market cap of $4.4 trillion is twice the size of the entire UK stock market, making it a significant holding for most pension investors.
When Will the Bubble Burst?
Timing the market is impossible, and attempting to predict a correction could lead to worse outcomes in the long run. Hollands suggests that while fears of an AI bubble have been growing, bubbles can persist for a long time before bursting.
"Second-guessing the top of a market is extremely challenging. Instead of trying to decide whether it's time to bail out completely, it's best to review your investments and consider rebalancing if you're heavily exposed to US equities and AI-linked stocks," Hollands advises.
Khalaf agrees, adding, "You shouldn't dismiss AI entirely if the US technology sector continues to perform well. It's a good time to assess your exposure and ensure you're comfortable with it."
Learning from History: The Dotcom Bubble
Some experts draw parallels between the AI boom and the dotcom bubble, which ran from 1995 to March 2000. The dotcom bubble eventually burst, leading to crashing prices and the demise of many overvalued internet companies.
Khalaf reminds us, "No one needs to be reminded of what a bursting bubble can do to wealth. An S&P 500 investor in March 2000 saw a £10,000 investment shrink to just £6,000 over the next three years. A Nasdaq 100 investor would have been left with less than £3,000."
The markets also experienced significant corrections in the five years leading up to the dotcom bubble's burst. The NASDAQ Composite index dropped more than 10% on three occasions during that period, and the market dropped almost 30% between July and October 1998 before rebounding before the 2000 crash.
Are We in the Foothills or Nearing the Summit?
Hollands raises the question: are we at the 1997 or 1999 stage of the AI investing mania, which began three years ago? AI infrastructure is seeing explosive growth in capital spending, but these phases typically last for multiple years, suggesting we may still be in the early stages.
Protecting Your Investments
Diversification and time in the market are key to investing. These principles will shield most investors from permanent catastrophic losses. Warren Buffett's parting message, in his final annual letter to shareholders at Berkshire Hathaway, is timely: "Keep calm and stay invested."
There's a risk in being overly cautious during uncertain times. According to JP Morgan Asset Management, seven of the market's ten best days in the last 20 years occurred within two weeks of the ten worst days. In other words, investors enjoyed the largest returns in the aftermath of significant crashes.
Diversifying Beyond AI
Looking back at the dotcom boom and bust, Khalaf emphasizes the risks of both over-investing and under-investing. While the potential for significant losses during a bubble is real, the cost of missing out on upside gains should also be considered.
Hollands suggests diversifying portfolios beyond shares, into asset classes like gold, infrastructure, and short-dated government bonds. He also recommends geographic diversification, highlighting the UK FTSE 100's 21% total return this year, compared to the S&P 500's 8% return, where UK investors faced currency losses.
European, emerging markets, and Japanese equities have all outperformed the US market this year, Hollands adds.
Khalaf suggests an equal weighting approach, dividing a portfolio equally between the five main regions: US, UK, Europe, Japan, and emerging markets. This spreads risk globally but may result in underperformance at times, requiring regular rebalancing.
Choosing an active global fund, managed by an expert, rather than a passive fund tracking a specific market index, can also help mitigate risk, although it comes with higher investment fees.
According to AJ Bell research, the average active global fund holds about 10% less in the US than the typical global passive fund. By investing in active global funds, investors leave regional allocation decisions to the fund manager, although some funds may have higher US weightings.
Final Thoughts
The AI bubble debate is a complex and controversial topic. As an investor, it's crucial to assess your exposure and ensure you're comfortable with the risks. While the potential for significant losses exists, so does the opportunity for substantial gains. The key is to stay informed, diversify, and maintain a long-term perspective.
