If you’ve looked at your brokerage account this weekend, you might be feeling a bit of whiplash. The S&P 500 has been on an absolute tear lately. We’re talking about a index that basically gained 21% over the last year and shot up over 40% since the lows we saw back in April 2025. It feels good. Maybe too good? Honestly, that’s the vibe on Wall Street as we hit Saturday, January 17, 2026.
The big indices took a tiny breather yesterday to close out the week. The S&P 500 dipped about 0.06% to land at 6,940, while the Dow Jones Industrial Average slipped about 83 points. It's not a crash. Not even close. But there is this weird, underlying tension in the today stock market news that wasn't there a month ago. People are starting to whisper about "bubbles" again, and for once, it’s not just the permabears on Twitter.

The Buffett Indicator is Screaming
Have you heard of the Buffett Indicator? It’s a favorite of the Oracle of Omaha himself. Basically, it’s a ratio that compares the total value of the U.S. stock market to the country's GDP. Warren Buffett once said that if this ratio hits 200%, you are "playing with fire."
Right now, that ratio is sitting at 222%.
That is higher than it was before the dot-com bubble burst. It's higher than it was in late 2021 before the 2022 bear market. Does that mean the floor is going to fall out tomorrow? No. Indicators aren't crystal balls. But it does mean that valuations are stretched to a point where there is almost zero room for error. If a company misses earnings by a penny, the market might just lose its mind.
The Great Rotation: Small Caps vs. Big Tech
One of the most interesting things in the today stock market news is how the "Magnificent Seven" aren't the only show in town anymore. For years, you just bought Nvidia or Microsoft and went to sleep. But 2026 is starting to look different.
Small-cap stocks, tracked by the Russell 2000, are actually outperforming the big guys right now. While large caps have barely moved—up maybe 0.5% year-to-date—small caps are up over 5%. Why? Because people are finally looking for value outside of the AI frenzy.
What's Moving the Needle Right Now:
- Bank Earnings: PNC Financial recently saw a 25% jump in profits because of deal-making and higher interest payments.
- The AI Hangover: Tech is actually the worst-performing sector so far this year, down about 0.40%.
- The "One Big Beautiful Bill Act": New fiscal stimulus is starting to trickle down to smaller domestic companies, giving them a boost that the global tech giants aren't feeling as much.
The Fed Problem Nobody Is Talking About
Everyone is obsessed with when the Federal Reserve will cut rates. The consensus used to be "any day now," but the data has been surprisingly strong. Jobless claims are at their lowest levels since late 2025, and the U.S. economy grew at a 4.3% clip in the third quarter.

Because the economy is so "hot," the Fed doesn't really have a reason to cut rates yet. In fact, market expectations for a rate cut have been pushed all the way out to July 2026. This is "good news is bad news" territory. If the economy stays strong, rates stay high. If rates stay high, those stretched valuations we talked about earlier start to look even more dangerous.
What You Should Actually Do
It’s easy to get caught up in the headlines and want to sell everything or, conversely, FOMO into the next "quantum computing" stock. But let’s be real. Markets don't go up in a straight line forever.
If you’re looking at your portfolio, check your exposure to the tech giants. If 80% of your money is in three stocks, you’re basically asking for a headache when the rotation deepens. It might be time to look at some "boring" sectors. We're seeing companies like Waste Management (WM) trade about 10% off their highs—these are the "steady Eddie" stocks that tend to survive when the speculative stuff starts to smoke.
Your Weekend Checklist:
- Rebalance: If your tech winners now make up way too much of your pie, trim a little. Take some profit. It’s okay to have cash.
- Watch the Earnings: Netflix and United Airlines report next week (Jan 20). These will be the real test of whether consumers are still spending.
- Ignore the Noise: Don't panic sell because of a 0.06% dip. But don't ignore the fact that the Buffett Indicator is at record highs.
The market is currently in a "wait and see" mode. We’ve got Davos happening next week and more earnings on the horizon. The best move right now isn't to be a hero; it's to be diversified.
Actionable Insights:
Log into your brokerage account this weekend and calculate what percentage of your portfolio is in the top 10 S&P 500 companies. If that number is over 30%, consider researching mid-cap or value-oriented ETFs to balance your risk before the next major earnings volatility.
