The Market's Safety Cushion Just Disappeared

Stocks and the 10-year now pay you about the same. That changes which stocks deserve your money.

September 25, 2026

The S&P 500 trades around 19 times forward earnings, an earnings yield of roughly 5.2%. The 10-year Treasury now pays about the same with zero earnings risk attached.

When the extra pay for owning stocks shrinks to almost nothing, the market gets picky about what it rewards. Here's how to land on the right side of that sort.

How We Got Here

Yields didn't climb on one headline, and you should know all three drivers. The economy won't slow down: S&P Global's flash composite PMI hit 58.4 in September, the fastest private-sector growth in more than five years, and input costs rose the most since October 2022.

The Fed hiked in mid-September, and New York Fed President John Williams now calls another hike by year-end a reasonable expectation. Futures put the odds of an October move at roughly three in four.

And Washington keeps borrowing. A $44 billion 7-year note auction cleared at 5.085% on soft demand. No 7-year sale has paid that much since 1993. With Brent back around $100, you can see why bond buyers have little reason to rush in and lock up long-term money.

Stock valuations have already started to give. The S&P's forward multiple slipped from about 20.4x at the end of June to around 19x. Earnings growth did the heavy lifting to keep prices up.

Why a Zero Premium Matters to You

When stocks paid a fat premium over bonds, the market forgave a lot. Missed quarters, fuzzy guidance, profitless growth. Money had nowhere better to go.

That forgiveness is gone. Every dollar you put in a stock now has a real alternative: a Treasury paying over 5% for doing nothing. So the market asks a harder question of every company you own. Is its earnings growth fast enough to beat a guaranteed 5%?

Companies that can say yes keep their multiples. Companies that can't get repriced. That's not a crash call. It's a sorting mechanism, and it's already running.

Where the Sorting Shows Up First

Look at the scoreboard. Utilities, the classic bond substitute, fell to a 52-week low as a group. Real estate slid. Long-dated Treasuries hit a 52-week low too.

Meanwhile, chip stocks rallied nearly 5% over the past week and the Nasdaq outran the S&P. Money isn't fleeing stocks. It's fleeing the stocks that behave like bonds without the growth to back it up.

What Breaks When Yields Go Vertical

Here's the part to plan for. Something always breaks when rates rise this fast. 2022 was UK pensions. 2023 was regional banks. This time the pressure points are different. Just as real.

Bond volatility is already flashing it: the MOVE index jumped from about 80 to above 100 in a matter of days. Commercial real estate is rolling into refinancing at rates that don't work for the existing debt stacks.

Private credit funds that borrowed short and lent long have a duration mismatch staring back at them. If you levered up during the 2020 to 2022 free-money years, you have a math problem coming due.

A market at 19x forward earnings with a 10-year above 5% closes that gap one of two ways. Earnings keep growing fast, or multiples come in. Ask yourself honestly which of your holdings can do the first.

Power Demand Surges (Sponsored)

Something new is plugging into the power grid and draining it — something that can devour the electricity of 100,000 homes at once, likely being built in your state right now.  

In some states, bills are already up 20% in a year, and James Altucher believes that's just the start.  

So he's identified the one company in prime position to facilitate a plan that’ll let you flip this rate hike into a profit.

How to Position for It

Demand earnings growth above 5%. If a company can't grow profits faster than a Treasury pays, you need a very good reason to own it at a premium multiple.

Own businesses that earn more when rates and volatility rise. Brokers and exchanges collect on customer cash and trading activity, and both are running hot.

Favor companies that fund themselves. Backlogs, free cash flow, nothing to refinance. Watch the balance sheet, not the P/E.

Keep bond duration short. Two-year Treasuries pay you well to wait. Long bonds are still in the path of the selling.

Cut the bond proxies. Utilities and REITs priced like bonds are losing to actual bonds.

What This Means For You

The 2020 to 2024 playbook (buy growth at any price, finance it on the cheap) is done. Reorient around businesses that either benefit from higher rates or grow fast enough not to care.

That means brokers and exchanges. Cash-generative industrials with long backlogs. AI suppliers growing earnings well above 5% a year. And it means being deeply suspicious of anything highly levered, long-duration bonds, and speculative growth names trading on 2028 revenue projections.

Own real estate? Know your debt maturity schedule. Own tech? Know how the company funds capex. This is a stock-picker's market, and the macro is doing half the work of sorting winners from losers. Your job is to spot the disconnects first.

Actionable Stuff

Run the 5% test on every holding. Take the earnings yield and add a realistic growth rate. If it doesn't clearly beat what a Treasury pays, trim it.

Own the toll collectors on volatility. Exchanges and brokers get paid on volume and customer cash, and both are near records.

Own the electrical grid buildout. AI data centers need power now, and the contractors building it have multi-year backlogs at fat margins. Look at the mechanical and electrical guys, not the hyperscalers themselves.

Sell any bond fund with 15+ year duration. If you own TLT or long-dated corporate bond funds, you're on the wrong side. Move to short duration or floating rate.

Custom silicon over general-purpose. The AI capex story is real, but it's rotating toward custom accelerators. That's where the growth that clears a 5% hurdle sits.

Top Picks

Interactive Brokers (NASDAQ: IBKR)

IBKR earns more when rates stay high and markets get busy, and you're getting both at once. It earns net interest on customer cash and margin balances, and August client margin loans hit $101.5 billion, up 41% from a year earlier.

Client accounts grew 35% to about 5.5 million. With the Fed hiking instead of cutting, that interest income isn't going away.

Catalyst: Q3 results on October 15.
What to watch: a sharp drop in margin balances or a surprise dovish Fed pivot would kill the thesis.

Marvell Technology (NASDAQ: MRVL)

Marvell is the growth leg here, and growth is what survives a zero equity premium.

Its custom silicon business is winning hyperscaler ASIC work, and its optical connectivity business (the plumbing that lets AI chips talk to each other at full speed) is one of the few franchises of its kind.

Management guided fiscal Q3 revenue to about $3.15 billion, more than 50% growth from a year earlier. The stock isn't cheap and has already run hard off its lows, so this only works if earnings keep compounding well above 5% a year.

Catalyst: hyperscaler capex commentary on October earnings calls, then Marvell's fiscal Q3 print around the start of December.
What to watch: slowing hyperscaler capex or a lost customer program would hurt your setup.

EMCOR Group (NYSE: EME)

EMCOR builds the mechanical and electrical guts of data centers, hospitals, and industrial facilities. Second-quarter revenue hit a record $5.15 billion, up almost 20%, on a multi-year backlog tied to the AI infrastructure buildout.

It generates cash and doesn't need to refinance anything, so bond market drama barely touches your position. The stock is well off its highs after a summer pullback, so your entry isn't heroic.

Catalyst: Q3 earnings in late October.
What to watch: any slowdown in commercial construction bookings or a hyperscaler capex reset.

CME Group (NASDAQ: CME)

When rates move this fast, everyone hedges, and CME collects a fee on every contract. Treasury futures volume rose 15% from a year earlier to 11.8 million contracts a day in August, and total volume posted its second-highest August on record.

Bond volatility has only picked up since. The stock is well below its highs, so you aren't paying a peak price for peak activity.

Catalyst: September volume report in early October, then Q3 results on October 21.
What to watch: a fast calm-down in rates volatility, or rivals making real inroads in Treasury futures.

Bottom Line

The Big Takeaway: Stocks now pay you about what a Treasury does. The cushion for owning risk is gone.

What It Means: The market will keep rewarding earnings growth that clears 5% and punishing anything priced like a bond without a bond's safety.

How To Play It: Rotate toward brokers and exchanges, AI infrastructure builders, and suppliers with real growth, plus short-duration fixed income. Cut long bonds and bond proxies.

Setup Scorecard

Entry Zone: IBKR $84 to $90 (about $90 now). MRVL $240 to $260 (about $259). EME $710 to $750 (about $752). CME $255 to $270 (about $269). Add short-duration Treasury exposure (1 to 2 year) on any yield spike.

Target: 15-25% upside over the next 12 months on the equity picks if the 10-year holds between 4.75% and 5.25%. Front-end Treasuries hold coupon plus modest price gains if the Fed pauses.

Stop Loss: Trim the equity names if the 10-year breaks decisively above 5.50% (multiple compression accelerates) or drops below 4.25% (the rate and volatility tailwind for IBKR and CME fades). Cut MRVL on any hyperscaler capex guide-down.

Catalyst Timeline: Next 2 weeks: August PCE (Sept 30), September jobs report (Oct 2), Fed speakers. Next 4-6 weeks: IBKR (Oct 15), CME (Oct 21), EME (late October), then MRVL around the start of December. Ongoing: Treasury auctions and Middle East headlines.

Confidence Level: High on the macro framework (rates stay elevated, inflation sticky). Medium-high on the individual picks. IBKR and CME are my highest-conviction names given their direct leverage to rates and volatility.
