While most investors have spent 2026 watching their portfolios bleed, one group has been quietly having a brilliant year — energy.

The S&P 500 energy sector is up over 34% year-to-date. Companies like Exxon and Chevron have been on an absolute tear. On a day when the broader market is down, energy stocks are often the only green on the screen.

So why?

It comes back to oil. The conflict in the Middle East has raised serious concerns about supply disruptions through the Strait of Hormuz — one of the most important chokepoints for global oil shipping. When the market worries that oil supply could be restricted, oil prices go up. And when oil prices go up, energy companies make significantly more money. Their profit margins expand almost automatically.

For anyone new to investing, this is one of the most important concepts to get your head around early: sectors don't all move together. When geopolitics disrupts a commodity like oil, it creates winners and losers across the market simultaneously. Energy wins. Airlines lose. Consumer goods companies get squeezed. Understanding those relationships gives you an edge that most casual investors don't have.

So should you buy energy stocks now?

That's the question everyone's asking — and the honest answer is it's complicated.

The easy money in energy has probably already been made. A 34% gain in a few months is enormous. The risk now is that if the Middle East situation resolves faster than expected, oil prices could fall sharply and take energy stocks with them. That kind of reversal can wipe out months of gains in days.

That doesn't mean energy is a bad place to look. It means you need to be selective and aware of the risk you're taking on. Established names with strong balance sheets are a very different proposition to smaller, more speculative energy plays.

Keep the sector on your radar. Watch how the geopolitical situation develops. And remember — buying something because it's already up a lot is one of the most common mistakes new investors make.
