In this blog post, I (finally) take the focus off the artificial intelligence (AI) boom/bubble. Instead, I want to look at whether there are other factors investors should be considering when it comes to time to rebalance portfolios, and as 2025 concludes and 2026 commences.

History might not repeat, but it rhymes – especially when markets climb to record highs. Indeed, as markets peak, so does collective optimism. Consequently, experts, economists, and central bankers alike tend to downplay the rising risks, anchor to the “new era,” and declare that ‘this time is different’ – the four most dangerous words ever uttered in investing.
