Move Over, Mercury Retrograde: My Only 2026 Prediction is “All-Weather”

There’s a lot of collective wisdom about the challenge of forecasting markets and the economy. Warren Buffet once famously said: “”Forecasts may tell you a great deal about the forecaster; they tell you nothing about the future.”

In an even more scathing take, courtesy of economist John Kenneth Galbraith, “The only function of economic forecasting is to make astrology look respectable.”

Early last year, I myself made some ETF predictions. Among my calls, I forecast a moderation in the ETF asset gathering pace; we went on to have a record year of inflows. I also expected small-caps to shine, given concentration and valuation concerns; small-cap ETFs struggled and faced outflows most of the year. So, I’ve personally helped give astrology a lot of credibility.

But it’s January, and making predictions for a new calendar year is one of our favorite sports.

My Prediction

Uncertainty remains a buzzword going into the fourth year of a bull market where many investors remain bullish but are also growing cautious. As an anecdote, in a late 2025 advisor survey we did at VettaFi, when asked about expectations for the S&P 500 in 2026, about 62% of advisors said they were bullish, looking for 10%-plus returns this year. But the remainder were calling for rangebound to lower price action.

Uncertainty, as in policy, trade, rate, growth and geopolitical uncertainty, continues to feed into caution as the market extends its bull run while remaining top-heavy and richly valued. With that backdrop, I’m going to make one single prediction this year: 2026 will be the year when all-weather investing makes its mark.

Consider that another advisor insight we took away from our surveys in late 2025 was that managing volatility and downside risk while maintaining stable returns (or better) ranked highest among advisor priorities going into the new calendar year. That pursuit, in the context of uncertainty, is prime territory for all-weather investing.

In the ETF space, there are different ways to think about all-weather investing. with solutions that can deliver broad diversification — aka: the secret to resilient portfolios — or laser focused exposures, tactically navigating the market’s ups and downs.
