ARK Invest CEO Cathie Wood said stocks can keep rising even with the 10-year Treasury yield above 5%, pushing back on the assumption that higher borrowing costs automatically cap equity gains. Her comments came after ARK's Frank Downing posted a chart plotting Treasury yields against the S&P 500 going back to 1980, which showed the 10-year at 5.18% and the index near 7,743.
Wood's argument isn't that rates don't matter. It's that the relationship has been backwards for most of the past fifteen years.
Rates, Fed control, and a 45-year chart
Wood wrote on X that when rates sat between 0.5% and 2%, the Federal Reserve — not the market — was setting the price of money. Above 5%, she argues, that dynamic flips. Her reference point is 2017, when the Fed raised rates and long-duration stocks still ran hard. In her September 22 investor letter, Wood leans on 230 years of data to make the case that the slide in rates from 1981 to 2021 was the anomaly, not the norm. Before the Great Depression, she notes, 5% to 6% yields were ordinary.
That framing cuts against the knee-jerk read that every tick higher in the 10-year is a hit to growth names. Wood expects long-term yields to settle near 5% to 6% as technology lifts productivity and growth, with short-term rates climbing to 6% to 8% alongside nominal growth.
The inflation data gap
Part of Wood's case rests on the idea that official inflation figures are running hot. She points to real-time data, citing Truflation's July headline inflation at 2.5% against the government's PCE price index at 3.7%. Nearly a full point sits between those two numbers, and Wood is betting the market will eventually price the cooler one. She also suggests balanced portfolios could carry more stocks than the classic 60/40 split.
Not the only one making this bet
Goldman Sachs' Anshul Sehgal has taken a similar line, favoring AI exposure over bonds. The disagreement is loud on the other side. Janus Henderson macro head Michael Contopoulos warned that the market is nearing its top as Fed tightening keeps pushing yields higher.
Traders are also weighing a possible October Fed rate hike, a move that would pressure risk assets broadly, Bitcoin included. The whole debate comes down to one question: can earnings grow faster than borrowing costs? If yes, Wood's 5% world is workable. If no, Contopoulos gets the last word.
What to watch
The October Fed meeting is the next real test. A hike would sharpen the argument on both sides fast.
