Whisper it softly, but is some of the investor fervour around Nvidia cooling just a little? The chipmaker has been a phenomenon, riding the surging demand for its artificial intelligence-empowering chips. The stock has jumped 180 per cent this year, fuelling about a fifth of the S&P 500’s gains in the process.

But trading volume in Nvidia has slowed in recent months with the average number of shares changing hands down 40 per cent from the first half of the year. And over the past six months, its shares are up just 3 per cent compared with more than 11 per cent for the S&P 500. In the last month, Nvidia shares have actually fallen about 9 per cent.

The retreat may simply be year-end profit-taking but it comes as investors consider how the developments in AI will play out in 2025 — probably one of the biggest new year calls they have to make given how important the technology is in driving returns.
