Happy New Year and welcome to the first edition of the Week Ahead for 2025.

As it’s still pretty quiet on the company reporting front next week I am using this article to be a bit more ambitious with my look ahead. Rather than just a week, this article will contain some of my thoughts about the outlook for the global stock markets in 2025.

US markets to continue to grow

The US markets remained the envy of the world’s investors in 2024.

The S&P 500 climbed 24%, driven by the continued demand for AI shares and the ‘Magnificent 7’. The latter rose by a collective 63% last year, with NVIDIA (NSQ:NVDA) leading the way, up 178%. Together these seven super-stocks are now worth $17.5trn - that’s equivalent to 40% of the S&P 500.AD_4nXenX1CjayZf4zhsZt2P_eYj8YkDp2-GQ23EVSspip1IqbfEXYupEWbJkKGPCb2ULn2upZwWN8bUeMO4n1qeGX7Z3iPAX9PUWXcALCFtBb2q-sEFMSf3aNeoLYPWLNwQjOMb1VPZqQ?key=ke6BnSliy2H7_quhykA9BZ75

These stocks now also have mega-valuations, trading on an average of 48 times forecast earnings - a level which for many risk-averse Brits leaves an uncomfortable taste. But I am with the fund managers like famed US short seller Carson Block who recently told Bloomberg TV, “just close your eyes and buy probably Magnificent 7”.

The trends which drove these stocks (and the market as a whole) higher in 2024 look set to persist in 2025. Firstly, artificial intelligence, which really is a market still in its infancy. In November, the chief executive at semiconductor company Broadcom commented that the total addressable market for AI is expected to rise from $20bn to between $60bn and $90bn in the next three years.

Secondly, fund inflows. The labour market remains strong in the US which tends to signal positive inflows, especially into the biggest of index trackers. And inflows fuel a virtuous circle of demand and growth, which will help support the share price performance of the biggest stocks.

The last time the S&P 500 managed three consecutive years of 20%+ growth was between 1995 and 1998. After rising 24% in both 2023 and 2024, I am optimistic that this feat could be achieved again this year.

And it’s not just the biggest stocks that I am positive about. Economic trends in the US favour companies of all sizes,…
