The market’s playing “good vibes only”
The S&P 500 just ripped 1.48% higher on Monday, and traders are now betting the index will open up again Tuesday. That’s the market version of rolling out of bed, checking the weather, and deciding the whole week might actually be okay.
What changed?
A few things flipped the switch:
- Iran tensions cooled off after President Donald Trump said he called off planned U.S. strikes and that talks with Tehran would resume.
- Oil prices slid, which is basically Wall Street’s way of saying, “Cool, maybe inflation won’t get a fresh caffeine shot.”
- Megacap tech woke back up, with Amazon topping a $3 trillion market cap and peers like Meta, Nvidia, Alphabet, and Microsoft helping drag the index higher.
Why investors care
This isn’t just a one-day sugar rush. The rally says investors are once again willing to lean into the AI trade and shrug off some of July’s tech-sector jitters. Add in stronger earnings expectations, and you’ve got a market that’s trying very hard to remember it likes risk.
Polymarket traders were pricing in a 77% chance the S&P 500 would open higher Tuesday, which is a fancy way of saying the crowd thinks the momentum still has legs. But there’s a lot on deck — factory orders, trade data, and earnings from names like AMD, Caterpillar, and McDonald’s — so the tape could still get yanked around.
Big picture: if oil keeps easing and tech keeps acting like the cool kid again, the market may have enough fuel to keep the rally going. If not, well, Tuesday mornings are very good at humbling everybody.
