Stocks are battling a powerful force: a 5.3% risk-free rate. The question is whether earnings can reach escape velocity before gravity takes over.
KEY TAKEAWAYS
The market is rising despite extremely restrictive bond math. Stocks are hitting records while the 10-year Treasury yield sits near 5.3%, creating an unusual tension between valuations and interest rates.
Higher discount rates punish long-duration growth stocks disproportionately. Companies whose cash flows arrive far in the future lose substantially more theoretical value when WACC rises than mature companies generating cash today.
The equity risk premium has essentially disappeared using a simple earnings-yield comparison. A roughly 5.23% S&P 500 earnings yield is competing directly with a roughly 5.3% Treasury yield.
Exceptional earnings growth is currently providing the market’s thrust. Strong earnings forecasts, upward revisions, and unusually positive corporate guidance are allowing profits to grow faster than stock prices.
Free cash flow is becoming increasingly important. Companies capable of financing their own growth are much better positioned if elevated interest rates persist.
MY HOT TAKES
High Treasury yields do not automatically mean stocks must fall. They raise the hurdle rate, but sufficiently strong earnings growth can overwhelm the valuation compression caused by higher discount rates.
The biggest vulnerability is not necessarily expensive stocks–it is distant cash flow. Businesses whose valuations depend heavily on profits many years from now carry enormous interest-rate sensitivity.
Investors should stop treating revenue growth as synonymous with economic value creation. In a 5% risk-free-rate world, free cash flow increasingly separates sustainable growth from expensive growth.
The disappearing equity risk premium deserves far more attention than it is getting. Investors are accepting equity volatility while the earnings yield on stocks is roughly equivalent to what Treasuries offer without equity risk.
The market can remain expensive-looking far longer than conventional valuation models suggest if earnings keep accelerating. The real warning signal would be simultaneous weakness in earnings revisions while long-term Treasury yields remain elevated.
You can quote me: “Revenue gets you off the pad, cash flow gets you into orbit.”
Earth looks so small from up here. When I was a kid, the most important piece of real estate on my block was the stretch of sky–above my block. That's where the Spaldeen went–that pink rubber ball every New York kid owned–and the unofficial championship of the block went to whoever could throw it highest. I was pretty good, not great 🤣 , and I learned something every single time–the ball always came back down. Always. You could throw harder, you could put your whole body into it, you could swear it was going to clear the roof of the tallest building on the street–and gravity would collect it anyway. I was sure that nobody on my block had heard of Isaac Newton, but every one of us understood his good work. What goes up comes down. It took me years, and a couple of decades on Wall Street, to learn the footnote to that rule. It isn't actually absolute. Technically, if you throw something fast enough…er, say about 11.2 kilometers per second, which is roughly 25,000 miles an hour–it doesn't come back. It escapes. That's not a kid's game anymore–that's actually rocket science. And right now, the stock market is trying to do rocket science with a 10-year Treasury yield sitting near 5.3%.
Take a look at the launchpad. Yesterday, the Nasdaq closed at another record, the S&P 500 climbed better than half a percent, and even the Dow tagged along for the ride–all while the 10-year Treasury yield pushed to levels we haven't seen since before the financial crisis. And the rocket with the most fuel in the tank? Fittingly enough, an actual rocket company. SpaceX jumped more than 7% after Morgan Stanley reiterated its Overweight rating with a $300 price target and called the upcoming Starship Flight 15–the one where they try to catch the ship on the way back down–the stock's most significant catalyst since its June IPO. The ball is hanging in the air a lot longer than it's supposed to. So the question every investor should be asking right now is a simple one–is that thrust, or is it just a really good throw?
Let's get something straight off the bat: a stock is worth the cash it will throw off in the future, discounted back to today–at least theoretically. That discount rate has a name–WACC (weighted average cost of capital–the blended return a company has to earn to keep both its lenders and its shareholders happy). And underneath every WACC on the planet sits the very same floor–the risk-free rate, which for most of the world means the 10-year Treasury. When that floor rises, every valuation model on Wall Street gets heavier. Every single one. No committee of central bankers votes on it. Nobody gets to argue with it. It's math–and math, like gravity, always shows up to collect.
Let me show you how it works with two make-believe companies (this is my math, not anybody's earnings report). Company A is a boring cash machine–it throws off the same pile of free cash flow (the cash left over after paying the bills and reinvesting in the business) every year, like clockwork. Company B burns cash for three years, then ramps like crazy, with the real money arriving in years eight, nine, ten and beyond. Now nudge the discount rate from 9% to 10%. Company A loses about 12% of its value. Company B loses about 22%. Push it to 11% and Company A is down about 21%–Company B is down about 37%. Same nudge–nearly double the damage. The further out your cash flows sit, the harder gravity pulls on them. That is exactly why, on any given afternoon, the Dow and the Nasdaq can look like they're orbiting two different planets.
Which brings me to SpaceX–which just might be the purest Company B in America. It went public on June 12 at $135 a share, raised $86 billion, and at the offering price was valued at roughly 67 times trailing sales–about triple what NVIDIA fetched at the time. It spent a good chunk of the summer below its IPO price before clawing its way back in August. Its first report as a public company was impressive on the top line–second-quarter revenue of $7.81 billion, up 92% from a year earlier. Then you turn the page. Capital spending came in at $18.4 billion–about 2.4 times revenue–with roughly $15.8 billion of it going into AI computing. Free cash flow for the first half of the year was roughly negative $25 billion. And here is a number that got a lot less airtime than it deserved: Starlink subscribers doubled to 12 million, but average revenue per user fell from $85 to $66. That's growth–but growth bought, at least in part, with price. Nearly all of the value investors are paying for sits years out, deep in the gravity well, discounted at a rate that just got heavier. Company B–Company B!
To be clear, I am not writing anybody's obituary. Rockets do leave the atmosphere–and SpaceX, of all companies, has proven that more than once. It is sitting on about $100 billion in cash and securities, which means it doesn't need to borrow at today's rates to fund its ambitions–and gravity is a lot weaker on a company that pays its own way. It reported a $48 billion contract backlog and $14.1 billion in newly signed cloud computing agreements. Management also talked–verbally, not as formal guidance–about hitting a $100 billion annualized revenue run rate by December, which would mean more than tripling quarterly revenue in about two quarters, and about AI investments paying for themselves in under a year. Ambitious? Absolutely. But if even a meaningful slice of that shows up, the math changes in a hurry. The question isn't whether the story is exciting–it is. The question is how fast the cash has to arrive to outrun a 5.3% risk-free rate.
Here's the part that matters even if you have never owned a single share of SpaceX–the entire S&P 500 is attempting a version of the same launch. The index trades at about 19 times the next twelve months of expected earnings. Flip that P/E upside down and you get what's called the earnings yield–about 5.23%. Now look over at the 10-year Treasury–also about 5.3%. Historically, investors have demanded a few extra percentage points of return for putting up with the gut-wrenching swings of the stock market instead of clipping a government coupon–that cushion is called the equity risk premium. By this simple measure, it's essentially gone–you are actually earning LESS! And here's the gravity check: if investors decided they wanted just one more percentage point of earnings yield to own stocks, that 19 times P/E would shrink to about 16. That's a roughly 16% haircut–with nothing else changing. No recession. No earnings miss. It’s just, um, more math.
Now for the thrust–and there is a lot of it. Analysts expect S&P 500 earnings to grow 29.5% in the third quarter, which would be the third straight quarter above 25%. For the full year 2026, the estimate is 32.4%. Even better, analysts actually raised their third-quarter estimates by 1.4% during the quarter, when over the past five years they have typically cut them by about 2.2%. And 62% of the companies that issued guidance for the quarter guided higher, against a five-year average of 40%. But here is the kicker most people miss: that forward P/E of 19 is actually below its five-year average of 19.8 and its ten-year average of 19.1. Read that again. 👈👀 Stock prices have gone up–but earnings have gone up faster. That is thrust beating gravity in real time. Remember that one-point shock that would knock the P/E from 19 down to 16? Earnings growth of roughly 19% would offset it entirely. Wall Street is currently penciling in a lot more than that.
So something has to give–it always does. Either yields come back down to earth, or earnings keep delivering escape-velocity growth, or valuations come down to meet the math. I am watching three things really closely these days. Watch the 10-year–and the 30-year behind it–because that is the floor under every WACC in your portfolio. Watch earnings revisions as Q3 season kicks off this week with Delta and PepsiCo and the big banks next week–if the revisions roll over, the thrust is fading. And watch free cash flow, not just revenue–revenue gets you off the pad, cash flow gets you into orbit. Then ask yourself a couple of honest questions. How much of what you own is Company A, and how much is Company B? And which of your holdings can fund their own growth without ever needing to knock on a lender's door at 5% plus?
Nobody on my block ever threw that Spaldeen into orbit. Not once. And it wasn't because gravity played dirty–it was because none of our arms were fast enough. The market's arm right now is earnings, and as long as earnings keep throwing at better than 25% a quarter, this market can keep hanging in the air a lot longer than the bond math says it should. When that arm gets tired, gravity will be waiting, patient as ever. Math usually wins–it's just that earnings are part of the math too. Earth does look small from up here. Let's just make sure there's enough fuel in the tank to stay. 🚀🚀
