The Bond Market Just Sent A Warning To AI Investors | Kenny Polcari

Well, good morning. Yes, I am Kenny Polcari, and today is Wednesday, August 19th, 2026, and we are now halfway through the month of August going into the final 2 weeks. And here are the things that you need to know to get your day started. Well, the bond market is speaking again. The question is, is anyone listening? Semis got clocked. It's the whole valuation thing again, the investment theme versus the investment calculus, because you need to understand the difference. Oil is up, gold is down, bond yields, well, they are holding steady. And what are we having for dinner tonight? We're gonna have the classic marry me chicken. Okay. I'd say, danger, Will Robinson, danger! That's a throwback to Lost in Space, 1965, 1968, something that the baby boomers can really appreciate. I can hear the robot saying that as I, as I stand here in front of you. Now, stocks continued to be sold yesterday. as investors considered what rising bond yields are going to mean for risk assets. And here's the hint: it's changing the price of money and it's creating an issue for valuations. It doesn't get any more complicated. And that caused the indexes to end the day lower. The Dow down 116, the S&P lost 53, the NASDAQ gave up 355 points, the Russell lost 40 points, the transports gave up 350 points, while the equal-weight S&P lost 40 points and the Mag 7 lost 310. And while that doesn't appear to be a disaster, 'cause it isn't, when you pull back the sheets, you're gonna find something very different because the semis got crushed again. The Philadelphia Semiconductor Index fell 5% as the sellers, mostly traders and algos, went into a frenzy, tripping over each other as they ran for the exits, unloading some of the hottest names in a very crowded trade. MU down 7%, SanDisk down 9%. Western Digital gave up 7%. Storage Technologies down 9%. AMD down 4%. Broadcom down 3%. Marvel gave up 8%. Nvidia lost more than 2%. And as you might expect, the Direxion Triple Leveraged Semi Long ETF lost 14.8%. But don't despair because the Direxion Triple Leveraged Semi Short ETF rose by 15%. So you see, there's always a silver lining. Now, the tech sector as a whole was the worst performing S&P sector, down 2.5%, followed by industrials, which are down 1.5%. Now, the money that came out of semis, it did find other opportunities in financials, up 0.5%, consumer staples up 1.1%, energy up 1.8%, and healthcare up 1.6%. Now, further down the line, we saw money move into big pharma. That was up 2%. Biotech was up 0.4%, aerospace and defense up 0.4%. So what happened to the semis? Did someone post something negative on Reddit? Did Mikey Burry announce that he was doubling down on his short bet? Did Nvidia pre-announce ahead of earnings next week? Did the AI story suddenly fall apart, or did the hyperscalers stop spending? Did demand for chips just disappear overnight, just like that? Poof! No, no, no, and no. None of that happened. But what did happen is that one of the hottest, most crowded trades on the street ran smack into a wall. And that wall is known as the bond market. And that is changing the investment calculus. And this is important because there is a difference between the investment theme and the investment calculus. So let's talk about that for 1 minute so you understand. The investment theme is the fundamental story, why you buy stock, the reason that you own it in the very first place, right? In this case, The AI theme remains enormous. AI adoption means massive data center construction, which means more chips. It means more memory. It means more power. It means more infrastructure. And that means more opportunities across the entire AI ecosystem, right? So there's energy, there's natural gas infrastructure, there's HVAC and cooling infrastructure, there's the electric grid, there's construction and engineering, there's concrete and cement, there's steel, copper. building materials, and real estate, right? That theme did not change on Tuesday. What changed was the calculus, the math that investors use to decide what they are willing to pay for that theme. The calculation includes expected earnings growth, valuation, interest rates, risk, the cost of capital, and what investors can earn somewhere else. And that is where the bond market comes in. Remember, the semis have been on fire. Memory names in particular have exploded higher. Expectations are enormous, and investors have been willing to pay up for tomorrow's earnings because the AI buildout appears almost limitless. But that buildout requires enormous amounts of capital. The hyperscales issued so far— well, they issued $121 billion worth of bonds in 2025, and this year they're already at $200 billion. And the Street estimates that that number could $250 billion by the end of this year. Broaden that out to the data centers, power infrastructure, and the rest of the AI ecosystem, and AI-related debt issuance could approach nearly $550 billion. Now, at the very same time, Scotty Bessant is flooding the market with Treasury debt to finance trillion-dollar government deficits. The AI— at the same time that the AI revolution is showing up at the bond market window, looking also for hundreds of billions of dollars. So in the end, everybody wants money, and bond investors are saying, that's fine, but you're gonna have to pay us for it. It's Econ 202. More supply means more competition for capital, means competition for capital means lower bond prices and higher yields, and higher yields means a higher cost of money. And that brings us right back to Tuesday's semiconductor rout and the broader market kind of unease, because when the risk-free rate is pushing towards 5%, Investors start asking much harder questions about what all the AI spending is ultimately going to earn, and spending in general, and more importantly, what they're willing to pay today for earnings that may not come for months or even years. That doesn't mean that the AI theme is broken. No, no, no. It means that the bond market is forcing investors to reprice that risk. And that's exactly what we've been discussing. The Fed doesn't have to do anything right now because the bond market is doing all that work, right? The Fed has left rates unchanged, yet the long end of the curve is moving higher. Higher rates don't matter, remember, until they do. And yesterday, apparently, they mattered. Now, next up is oil. WTI gained another $0.44 to settle at $84.94, while Brent added $0.15 to end the day at $91.02. No need to rehash why. The story hasn't really changed. Unrest and uncertainty in the Middle East, period. Now, remember, oil doesn't need another missile attack to stay elevated. It just simply needs Uncertainty to stay where it is. And right now, that uncertainty isn't going anywhere. It's, it's remaining uncertain. This morning, WTI is trading up another 55 cents at $85.50. Gold, well, that took a little bit of a breather yesterday, losing $81 or 1.8% to end the day at $4,335. And you can also blame the bond market. Why? Because gold doesn't pay you anything to own it. No earnings, no dividends, no interest. Investors buy gold for safety. Think geopolitical unrest. Okay, check that box. They buy it as inflation hedge. Okay, check that box. And foreign central banks will buy gold to diversify reserves and reduce dollar exposure and hedge risk. Okay, check that box. And here's the rub. When the US government bonds offer you 4.7% or 5% or more, the opportunity cost of owning gold changes. Why buy a non-interest-bearing asset when you can put that same money into risk-free treasuries that are going to pay you 5%? Oh, and that whole safety trade theme reason? Well, that went out the window, at least for yesterday. Anyway, this morning gold's trading at $4,342, which is just up a couple of bucks and remains in that $4,160, $4,500 trading range. Now on to the eco data, which shouldn't really be a surprise. Housing starts plummeted, falling 12%, well below the expectations of down 6%. Now think affordability. Mortgage rates are moving up. Current rates are 6.7% and likely going higher. Think about it for a minute. Higher rates just make home builders more cautious because it caused buyers to step back. So a decline in housing starts shouldn't really be a surprise. On the contra side of the eco data, it's really interesting. Manufacturing production number, it came in on target at +0.2%. And this is where the whole semiconductor story gets tossed upside down. Why? Because manufacturing output rose in July because it was Flat the month before. Business equipment production increased and production of semiconductors remained strong. Hello, anyone home? Think about it. Investors were dumping semiconductor stocks yesterday while the economic data continues to tell us that the AI infrastructure buildup remains alive and well. Which reinforces the point. Yesterday wasn't about AI demand suddenly disappearing. It was about the price investors are willing to pay for growth when the cost of money changes. Ta-da! So that's— see how it all comes back to the bond market? And that is the second lesson for today. Now, Eagle Data today is all about mortgage apps. I suspect they're going to fall. We're also going to hear from the FOMC, right? The minutes— we discussed this. The surprise is going to be if we find out that more than just the 3 dissenters were leaning hawkish. Right? They were meaning they were on the fence, asking the question, should we or shouldn't we? Either way, it is what it is. We have 3 weeks before the next meeting. But first, we have to get through the August Jackson Hole boondoggle that brings central bankers from around the world and economists to Jackson Hole, Wyoming. The theme this year for this symposium is called Financial Innovation Implications for Payments and Policy. Oh boy. Can you imagine the excitement in the room with that? I would not expect to learn anything about US monetary policy or quite honestly global policy at this symposium. And I don't think you should either. Earnings today include Estée Lauder, Target, and Lowe's, all before the bell. That's all about personal care and beauty, discount retail and consumer, and home improvement retail. Remember, Home Depot beat yesterday. Over in Asia, South Korea continues to get sold. It lost 5.8% overnight. Taiwan was down 1.3%. But again, both market centers are still up 54% year to date. So put it in perspective. European markets are churning around the unchanged line. Again, most of Europe is on vacation, earnings season is over, and there are no central bank announcements. US futures this morning are churning as well. Dow futures are up 7%, S&P is down 1%, NASDAQ is down 50%. While the Russell is down 6. The S&P closed at 7,691, down 53 points. Remember yesterday I said we were going to test a near-term support at 7,700? Well, we didn't. We closed just a hair below. The chart now suggests that we're in this kind of purgatory. Trendline support is way down at 7,520, and if bond yields continue to push higher, then a test of that trendline is more likely. Remember, volumes are subdued. Participants are away on vacation and moves can be exaggerated. Just look at what some of the double and triple levered ETFs can do, which is not a recommendation at all. These products are not necessarily for the retail investor. They are sophisticated, they react swiftly, and they can cut deep if you don't pay attention. On the other hand, they can reward you handsomely if you do it right. The key is to understand the risk that they pose. Period.

Okay, so now what are we having for dinner tonight? Well, this is a classic marry-me chicken. People make it, but this is a classic dish. It's a fan favorite and it's a family favorite, and it's simple to make and it's delicious to eat. If you've never done it, get ready, 'cause here you go. For this, you need thin sliced chicken breasts. You need salt and pepper, flour, olive oil, butter, 4 cloves of garlic sliced, 4 or 5 cloves, thyme, red pepper flakes if you're gonna use it, chicken broth, sun-dried tomatoes that you're gonna chop, heavy cream, fresh grated Parmigiano cheese, and fresh basil. You want to begin by seasoning the chicken with salt and pepper. Dredge it in flour and shake off the excess, right? You don't want flour all over. Just shake it off. Now, in a large sauté pan, you're going to heat up some olive oil and a little bit of butter. You're going to brown the chicken breast until it's golden on both sides and then take it out and set it aside. Now go back to that same pan, add another dollop of butter, and then turn the heat down to medium. Sauté the garlic and Add the thyme and the red pepper if you're using it. Now stir in the chicken broth and the sun-dried tomatoes. Let it all simmer together for 3 or 4 minutes. Right now you're going to add the heavy cream and you're going to add the Parmigiano cheese. You're going to mix it well. It's going to thicken up a bit, but keep the heat on simmer, not on high or medium-high. Turn it down to simmer. Now you're going to add back the chicken breast. You're going to let the whole thing simmer for 10 minutes, allowing the chicken to Marry the sauce. Then you're going to serve this with a mixed green salad and a side of maybe garlic herb rice is always good. In any event, it is a— looks like a glorious day here in South Florida. It was hot yesterday, about 95. Today the sky looks blue and it's already hot out again, but we are getting to the end of August, so the tide will certainly change. In any event, until tomorrow, take good care.
