Investors’ exuberance is fueling this year’s stock rally, but will key economic risks dampen the market’s mood?
Why it matters: The current bull run has lifted stocks from their springtime lows to higher levels in autumn. The artificial intelligence boom is one of the big factors driving it. Meanwhile, the Federal Reserve is dealing with the challenging situation of balancing the weakening job market and stubborn inflation. The Fed cut interest rates for the first time in 2025 in the third quarter, but the path forward from here is less certain.
Morningstar Inc Senior Markets Reporter Sarah Hansen discusses seven key market factors you should watch in Q4 2025.

Key Quote on Q4 2025 Market Factors
There are certainly some risks to the outlook right now. One of the things that investors have been really worried about this year, all year, actually is high valuations. So when stocks are fairly valued or highly valued, as is the case with many of those big tech stocks right now, there is a lot less wiggle room for them to recover from unexpected shocks, either to the corporate outlook or to the economy as a whole or on the policy side.
The counterargument to people who are worried about those high valuations is that the highest-flying tech stocks are putting up strong results that kind of justify the premium on their stock prices. And right now, it’s just impossible to know which of those is right. It might be that both are right. It might be we see something different. Just hard to say.

The Takeaway: Be prepared for market volatility in the final months of 2025 as the outlook for stocks, policy, and the economy remains uncertain. Sarah Hansen, senior markets reporter at Morningstar, reminds investors that markets rarely go up in a straight line. But as of right now, many strategists are telling Hansen that they’re optimistic about the market outlook and that the fundamentals look good.
More From Morningstar on Market Factors to Watch in Q4 2025
It remains to be seen whether the powerful stock market rally will continue in the face of mounting risk factors. Stocks climbed 8% in the third quarter despite concerns about high valuations, uncertain US trade policy, and a softening job market, writes Hansen in 13 Charts on Q3’s Tech-Driven Rally. Meanwhile, bond yields declined, while prices increased ahead of the Federal Reserve’s first interest rate cut since 2024. Some strategists are predicting elevated inflation and other risks could further steepen the yield curve.
Markets typically react to government shutdowns as “mini-crisis” events, according to Dominic Pappalardo, chief multi-asset strategist for Morningstar Investment Management. The responses usually spark a risk-off reaction where the following tends to happen: volatility rises, US Treasury rates rally, and stocks slightly sell off. Since 1974, there have been several shutdowns that have ranged from a few hours to more than a month. So, in that sense, they’ve been common. Pappalardo says investors should remain disciplined and confirm their diversified investment strategy matches their risk tolerance.
