Wall Street has a strange problem: the market still looks bullish, but almost every major macro signal is trying to talk investors out of believing it.
The S&P 500 remains near its 2026 record, semiconductor shares are still capable of pulling the broader market higher, and corporate earnings have held up better than many feared. Yet the same market is now dealing with a 10-year Treasury yield above 5%, oil above $100 a barrel and a Federal Reserve that has just raised interest rates for the first time since 2023.
That is not the clean backdrop investors usually associate with an easy bull market. So the better question may not be “are stocks going up?” but “what exactly is keeping them up?”
The bull case: earnings, AI spending and resilient risk appetite
The strongest argument for the bulls is that the market has absorbed a surprising amount of bad news without falling apart. Reuters reported on September 18 that the S&P 500 and Nasdaq finished higher while the Dow slipped, with chip stocks helping stabilize the broader tape after a volatile week.
Technology remains the market’s structural support. AI infrastructure spending is still large, hyperscalers continue to commit capital to data centers and computing capacity, and the semiconductor complex remains one of the few areas capable of generating enough earnings growth to offset weakness elsewhere.
There is also a simple market-behavior argument. When investors receive a combination of higher rates, expensive energy and geopolitical stress, and the major indexes still refuse to break decisively lower, that resilience matters. Markets often turn before the macro data looks comfortable.
And the S&P 500 is still only around 2% below its 2026 record, according to Reuters’ latest week-ahead analysis. That is hardly the profile of a market already in full retreat.
The bear case: the price of money is suddenly a serious problem again
The other side of the debate starts with bonds. A 10-year Treasury yield above 5% changes the math for equity valuation. Investors can earn a historically attractive nominal return from government debt without taking equity risk, while companies face a higher cost of capital at the same time.
That matters most for richly valued growth stocks. The farther into the future investors expect a company’s profits to arrive, the more damaging a higher discount rate becomes. The AI trade can keep working, but the valuation burden becomes heavier if yields stay elevated.
The Fed adds another layer of uncertainty. Its latest 25-basis-point increase took the policy rate to 3.75%-4.00%, and traders are now debating whether additional tightening will follow. That is a very different setup from the classic liquidity-driven bull market in which investors assume the next central-bank move will be a cut.
Oil may be the variable that decides the argument
Energy is the bridge between the inflation story and the equity story. Brent crude has remained above $100 as Middle East tensions disrupt supply expectations. If oil stays there, it can feed into transport costs, consumer prices and corporate margins.
That creates a stagflation risk: slower growth at the same time inflation remains too high for central banks to ease aggressively. Reuters described the current combination of higher energy prices and borrowing costs as a potential “stagflation cocktail” for global markets.
If oil falls materially, the pressure eases quickly. Bond yields could stabilize, inflation expectations could cool and the Fed would gain more flexibility. If oil stays high or rises again, the bull case becomes much harder to defend.
What I think the market is really doing
This does not look like a market that has clearly left the bull phase. It looks more like a bull market being forced to prove itself under harsher conditions.
The distinction matters. A healthy bull market does not require every economic indicator to be friendly. But it does require earnings to keep expanding, leadership to broaden beyond a handful of mega-cap names and investors to tolerate higher yields without continuously compressing valuations.
Right now, the market passes the first test only partially. Earnings remain supportive, but leadership is still heavily dependent on technology and semiconductors. It passes the second test unevenly: yields above 5% have not broken equities, but they have clearly increased volatility. And it has not yet passed the third test, because oil and inflation are still moving in the wrong direction for a clean risk-on environment.
The next move may be decided outside the stock market
For the next several weeks, I would watch four things before obsessing over index targets: the 10-year Treasury yield, Brent crude, the Fed’s language and the breadth of earnings revisions.
If yields retreat, oil cools and earnings estimates stay firm, the current pullbacks may ultimately look like consolidation inside an ongoing bull market. If yields remain above 5%, oil stays above $100 and earnings revisions begin turning lower, then the market’s proximity to record highs could become a vulnerability rather than a sign of strength.
So is this still a bull market? The price action says yes for now. The macro backdrop says that answer is being retested every day. That tension is probably the most important feature of the market heading into the next leg.
