Big tech companies have been a major source of wealth for investors in recent years. However, with this success comes the inherent risk of potential losses. The market has seen various signs that the high valuations of these tech giants may be unsustainable, such as monetary tightening, tariffs, and increased competition.

Last June, over $2 trillion was wiped out from the stocks of the top tech companies, known as the Magnificent Seven. While some of these losses have been recovered, there is still concern over further declines as more tech companies report their earnings, including Alphabet, Microsoft, and Arm.

Analysts have been speculating about the potential bursting of the AI bubble, with some predicting a significant market correction. Panmure Liberum conducted simulations that suggested a potential bear market if the AI boom were to slow down or reverse. In the worst-case scenario, tech stocks could plummet by over 70% in the first year.

In the event of a market crash, certain sectors like UK construction, infrastructure, and defensive sectors are expected to be more resilient. Retailers like Next and B&M, as well as construction companies like Balfour Beatty and Morgan Sindall, are projected to lose less than 10% of their market value.

While some remain bullish on big tech earnings, concerns have been raised about high valuations and supernormal earnings levels. The pace of AI adoption and the returns to businesses may not be sufficient to sustain current equity valuations. Rising expenses for AI companies and a lack of comprehensive AI strategies in many businesses are also factors contributing to uncertainty.

Investors should approach AI IPOs with caution, as there is a risk of hype overshadowing the true value of these companies. Panmure Liberum has warned that US AI listings may be overhyped and pose a significant risk to investors.

Overall, while the potential for AI to revolutionize industries is significant, investors should be mindful of the risks associated with investing in tech companies. It’s essential to conduct thorough research and consider the long-term sustainability of these investments.
