Financial experts have been warning for the past year of a potential stock market crash, attributing the risk to the popping of the artificial intelligence (AI) bubble. Despite these warnings, major stock indexes such as the FTSE 100 and the S&P 500 have continued to rise, with the FTSE 100 up 9% and the S&P 500 up 12% year-to-date. However, many commentators, fund managers, and economists maintain that a significant market correction is inevitable.

These anticipated falls are expected to be led by sharp declines in the share prices of large U.S. technology companies. Nvidia's stock price, for example, has seen a 940% increase over the last five years. Nevertheless, the consensus among some experts is that no stocks or markets will be immune and all will likely be dragged down.

Recalling the dot-com bubble burst in early 2000, the tendency for stock market bubbles to pop is a historical certainty. The primary challenges for investors lie in predicting the timing of such an event and determining the appropriate course of action. Options include remaining invested, selling holdings to move into cash, or ensuring a portfolio is sufficiently diversified to mitigate the impact of market downturns on long-term investment goals.

There are differing opinions on the best strategy. One former hedge fund manager suggested that government bonds are currently the only safe haven for investors, implying an imminent market crash and advising investors to sell their stocks. Government bonds are seen as increasingly attractive as yields continue to rise globally.

However, an alternative perspective suggests that as long as investment horizons are long-term and investors can tolerate potential short-term losses, staying invested remains a sound strategy. This view has been held by some financial journalists for decades and has historically proven effective. This does not mean, however, that investors should remain passive.

Portfolio Review and Diversification

Experts advise that now is a crucial time to ensure investment portfolios are robust and resilient. A portfolio makeover, including necessary changes, is recommended. Essential diversification should extend beyond stock markets and investment funds to include other financial assets like precious metals (gold and silver) and government bonds.

The recent surge in the prices of many U.S. tech stocks has led to portfolios becoming heavily weighted towards the U.S. market. Adjusting this imbalance is now suggested. Investors holding stocks from the 'magnificent seven' (Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla) are advised to consider trimming their positions, particularly if they hold substantial paper gains. This can be done within tax-advantaged accounts like ISAs or self-invested personal pensions to avoid capital gains tax (CGT). Outside these wrappers, individuals have a £3,000 CGT allowance per tax year, with subsequent gains taxed at 18% or 24% depending on the individual's tax rate.

Investors are also encouraged to examine their investment funds for significant exposure to the 'magnificent seven' or U.S. tech stocks in general. Factsheets should be reviewed, and if the level of exposure is a concern, taking some profits may be advisable.

Income-oriented investment funds are recommended as a diversifier, and gold and silver should also be considered for inclusion in portfolios. According to Ian Williams, manager of the Charteris Gold and Precious Metals fund, prices for gold and silver are expected to rise, driven by geopolitical uncertainty and the increasing demand for silver in electrification technologies like solar panels and electric cars. Direct exposure to rising precious metal prices can be achieved through funds that track the gold or silver price, managed by firms like iShares and Invesco.
