How did May treat you? If you own a diversified portfolio, the honest answer is probably: pretty well. Possibly better than you could expect, given everything going on in the world right now.
Â
The S&P 500, America's big index of 500 large companies, finished May at a record high, up around 5% on the month alone.
Global stocks broadly followed.Â
Â
So what drove it? Simple, really: companies made more money than expected. Not a little more — by the biggest margin in over four years. Profits were up, revenues were up, and analysts who had been quietly nervous about the year are now quietly upgrading their forecasts.Â
Â
Markets love nothing more than a positive surprise, and May
delivered several.
Â
Now, if you're thinking "but the world is a mess right now," you're not wrong. The US and Iran are still in an uneasy ceasefire. Oil prices were all over the place before calming down. AI stocks continue to do things that would have seemed implausible three years ago. And yet, markets went up. This is a useful reminder that markets are not a live broadcast of world events. They're a
collective bet on future profits — and right now, those bets are looking confident.
Â
Bonds are a different mood entirely. The 10-year US Treasury yield — think of it as a thermometer for how worried investors are about inflation — finished May at 4.45%. That's up, not down.Â
Â
What it's telling us is that inflation hasn't been
fully tamed. The US central bank (the Fed) kept interest rates on hold at 3.50–3.75%, and the idea of rate cuts this year is quietly being pushed to "maybe 2027." Not dramatic, but worth noting if you have a mortgage or any bonds in your portfolio.
Â
Gold has been the drama queen of the asset class world this year. It hit an all-time record above $5,600 back in January, then spent May cooling off around $4,500–4,550.
Still historically very high. What's holding it up? A mix of geopolitical nerves, a weaker US dollar, and the general sense that some people would rather own something physical and shiny than trust a government's balance sheet. Hard to argue with, frankly.
Â
Bitcoin hovered around $73,000–74,000. The headline of the month: Strategy Inc. — the company run by Michael Saylor, arguably Bitcoin's most famous cheerleader —
actually sold some Bitcoin. This is the investing equivalent of your vegan friend ordering a steak. Markets noticed. It doesn't mean Bitcoin is doomed, but it does suggest the "never sell" crowd is evolving its thinking.
Â
The VIX, a measure of market nervousness, sometimes called the "fear index", sat at a calm 15. Low fear. Which is either reassuring or a little suspicious, depending on your temperament. Mine leans
slightly suspicious.
Â
My takeaway: May rewarded people who stayed invested and didn't overthink it. That said, this rally is being driven by a fairly small group of tech and AI companies. If you zoom out, the average stock isn't doing nearly as well as the headline numbers suggest. Stay invested, stay diversified — but don't mistake a calm surface for still water underneath.
