Jon Quast: Elon Musk just pitched his next big idea. Welcome to Motley Fool Money with the Hidden Gems team. I’m Jon Quast, joined today by Matt Frankel and Rachel Warren. Today, we’re talking about Elon Musk’s big idea, as well as some other big ideas that we really like. But first, I wanted to avoid it, but we have to talk about it. Early this morning before the market opened, US President Trump announced that they’d have productive talks with Iran over the weekend. Of course, we all know that the operations happening in Iran have had a huge impact on oil prices. It’s been a roller coaster ride. I’m positive we have not reached the final chapter of this ride yet. But with the market up so sharply today, I felt like we needed to talk about it, acknowledge it. Rachel and Matt, the market was down last week, up sharply this morning. Was the announcement from the president that good? Was the news that good?

Matt Frankel: Well, yes and no. One thing. I mean, you said we try to avoid talking about the war, but it’s nice to talk about it on a somewhat positive note for a change. For one thing, take this news with a big grain of salt. As you said, we’re probably not close to the final chapter yet. The president decided to delay certain strikes, specifically on Iran’s energy resources after productive talks. Right after he said that, Iran quickly denied that any talks had actually taken place. Iran at the beginning of the war, if you remember, they said that I think it was their prime minister, is that what it’s called, was alive and well after he had been killed in air strikes. Who’s to say what did or did not happen? If talks happened, how productive they actually were, of course, this is two different sides, telling two kind of very biased sides of the story, I guess, I would say. But on the other hand, the market was clearly ready for any signs of de escalation in the conflict, and we finally got one. For the past few weeks, I don’t know about you guys, it seemed like the situation was gradually getting worse and more uncertain on a daily basis. It was a nice change of pace. Just to be clear, the war is still going on. I want to get that right out there. We’re not likely to see a broad, sustained rebound in the market unless further developments happen. Even after today’s move, my portfolio is still very much down. I don’t know if you’re in the same boat. Essentially, all that’s happened is that the president is agreeing to delay escalating the conflict even further. He’s not really dialing back to anything that’s already happening at this point. It’s just delaying what he threatened to do to escalate it even further. Keep that in mind.

Rachel Warren: Yeah, I think Matt laid that out really well. I do think the global markets are really looking for sort of any sign of relief. President Trump’s true social announcement of a five day pause, it was very specific to military strikes against Iranian power plants. That is nothing to say as just strikes across the country towards other military targets. But basically, what had happened over the weekend was President Trump had threatened to obliterate Iran’s energy infrastructure if the Strait of Hormuz was not reopened. We’re sort of seeing, this morning the sudden shift to a rhetoric of, quote productive conversations. I think that perhaps that is easing some fears of what has been feared would be a global energy crisis comparable to 1970s oil shocks. When the market opened this morning and we saw the Dow jump over 800 points, S&P 500 and NASDAQ rose about 1.4 and 1.6%, respectively, we saw European indexes flipped from losses to gains at the market open. Then Brent crude, of course, which had topped I think around 114 a barrel earlier in the day, plunged double digits after the news. Course, that could have changed as we are redo recording this podcast. We also saw a response from airline and cruisline stocks, right, which of course are companies that are very sensitive to fuel costs. Then conversely, you saw shares of energy stocks like Occidental Petroleum retreat a little bit. I think it’s important to underscore here the situation is very fragile. As Matt noted, Iranian officials have publicly denied that direct talks took place. There’s some suggestions that the move may be as a tactic to try to get energy prices to tamp down a bit. I do think that investors should expect the market roller coaster to continue even as this five potential window unfolds. I think it could get worse before it gets better. I don’t think we have seen even close to the end of this.

Jon Quast: That is the more news angle. This is what has happened. This is what is happening. But I want to take a step back and just advocate, ask some questions on behalf of our listeners. I think if I’m a listener to this show regularly, if I’m listening to Motley Fool Money, I’m hearing from the analysts regularly to take a long term view with investing. I want to take a long term approach to buying stocks, investing in these companies, and yet we’re seeing something so consequential oil energy prices. This is very consequential to the global economy, and they are behaving somewhat erratically. Social media post can come out and cause trillions of dollars of change in the stock market. I think I’m asking, if I’m a listener, how am I supposed to take a long term view when things can change so quickly on a day to day basis? Any thoughts that either of you can provide to our listeners that helps them understand how to contextualize this?

Matt Frankel: Sure. If I’m being totally honest, this is one of the reasons why I generally don’t own energy stocks in my portfolio. They can be more unpredictable than most of the other sectors I like to invest in. If you have stock in Chevron or Exxon or any of these really well run oil businesses, even, things like war, weather, if a hurricane happens, for example, they can move the price of oil dramatically through no fault of the company. The company can be doing everything it’s supposed to be doing, and you need to be prepared for that as an investor. We’ve seen massive swings even before the Iran conflict started, the worst than expected winter weather was driving the price of oil up. There’s a lot that can go wrong in oil. But you’re right, John, and you alluded to this. The moves in oil prices have much more economic implications beyond just higher or lower prices at the gas pump the transportation costs of getting food to grocery stores. There’s a bunch of different trickle down effects, but none of those are permanent. They’re all just ebbs and flows in the economy. Energy costs, transportation costs, materials costs. Those are all going to be a little bit erratic over time. But when you zoom out, the impact of transportation costs on things like grocery prices really tends to smooth out over time. If you’re an energy sector investor, be prepared for these swings. If you’re invested in stocks that have more secondary impacts of oil price swings than just know that it’s not a permanent headwind for the business. It’s just a temporary condition. If you’re invested in great businesses, then it’ll even out over the long term.

Rachel Warren: Yeah, I think those are really great points. I think it’s important to remember that so many of these elements are beyond our control as retail investors. It’s really, really important to focus on what we can control and the efficiencies that we can build into our portfolio. I mean as investors, when you’re hearing about oil prices swinging $30 a day or headlines that seem to change every few hours. I think the really important thing is to remember the difference between noise and signals. I mean, daily volatility is almost always noise, the market reacting to fear and uncertainty. Rather than actual long term damage to global businesses. That doesn’t mean that they’re not going to be impacts, these energy cost inputs, even if the war were to grind to a halt now, there will be some impact for that probably well into the end of the year. Historically, these whip saws that we see in the market, they can feel overwhelming in the moment, no matter what industries you’re invested in. They really do very rarely change the long term trajectory of really productive quality companies. You think of your portfolio like a house. A storm might shake the windows today, but if the foundation, which is hopefully a diversified mix of quality assets is solid, the house should still be standing long after the weather clears. Again, really focusing on building a robust, profitable portfolio, rather than trying to predict the next chapter of what will happen in the market. The other thing I’ll add is that volatility can really provide long term investors with opportunities to rebalance, to buy quality companies at a disc. Again, really staying diversified, keeping that long term mindset, it ensures that headlines don’t derail the financial future you’re trying to build. The goal is not to time the market, but to spend enough time investing in the market over the duration of your investing journey to really let the power of growth outweigh any temporary spikes that you might see in your portfolio.

Jon Quast: Well, whatever happens, you can be sure that we will join you along for the roller coaster ride. After the break, we’re going to talk about Elon Musk, and he’s anything but subtle. He gave the investing community plenty of buzz over the weekend. You’re listening to Motley Fool Money.

Mark Kistler: When Johan Rah received the letter on Christmas Day, 1776, he put it away to read later. Maybe he thought it was a season’s greeting and wanted to save it for the fireside. But what it actually was was a warning delivered to the Hessian Colonel, letting him know that General George Washington was crossing the Delaware and would soon attack his forces. The next day, when Raw lost the battle of Trenton and died from two colonial boxing day musket balls, the letter was found unopened in his vest pocket. As someone with 15,000 unread emails in his inbox, I feel like there’s a lesson there. Oh, well, this is the constant a history of getting things wrong. I’m Mark Kistler. Every episode, we look at the bad ideas, mistakes, and accidents that misshaped our world. Find us at constant podcast.com or wherever you get your podcasts.

Jon Quast: Welcome back to Motley Fool Money with the Hidden Gems team. So, Elon Musk did his best Bonnie rate impression over the weekend. He said, Let’s give something to talk about. He held an event in Austin on Saturday to talk about something his companies are launching called Terafab Rachel, what I Terafab?

Rachel Warren: Terafab is a $25 billion joint venture between **Tesla **SpaceX and XAI. MSC is framing it as the most epic chip building exercise in history. Terafab is going to be a vertically integrated semiconductor factory designed to produce an unprecedented one Terawatt or 1 trillion watts of AI computing power annually. Unlike traditional factories that specialize in one part of the process, Musk envisions that Terafab will handle everything, design, lithography, fabrication, packaging, under a single roof to bypass global supply chain bottlenecks. Tesla, this is a Musk. This is really about achieving total self reliance for the physical AI ambitions. I mean, the idea is the facility will mass produce the inference chips needed to power cyber cab robotaxis and optimist humanoid robots. Musk estimates that all current global chipmakers combined can only provide about 2% of the compute capacity his companies will eventually require. One final thing I want to note, I mean, there’s some major implications here for SpaceX, as well. About 80% of Terafabs output is earmarked for space based applications, specifically for a new constellation of orbital AI satellites. Basically the satellites will use custom chips to run massive AI workloads in orbit and take advantage of the vacuum of space for better thermal management and more solar energy than on Earth. It’s a very big promise that Musk is making a massive vision that he has for Tapat. It’ll be very interesting to see how this plays out.

Jon Quast: It was so interesting to hear Elon talking about how essentially they want to buy so much semiconductor products from their partners, but the partners just aren’t making enough to meet their needs, so they’re going to take it on themselves with this ambitious project. Matt, just how ambitious is it?

Matt Frankel: It certainly is ambitious, but first of all, keep in mind that, the Giga factory seemed like a very ambitious project at first, and that was delivered. But keep it in perspective, the three companies that you mentioned, XAI, SpaceX and Tesla, they have a combined valuation of well over $2 trillion, over 3 trillion, depending on who you ask. Spending 25 billion in CAPEX, even if it’s on the largest chip factory that will ever have been built in the world, it isn’t exactly a massive bet in terms of spending, especially when you consider Amazon is spending 200 billion on CapEx this year. Tesla has always liked to handle as much as possible internally. I mentioned the Giga factory with batteries. Take it with a grain of salt. Musk does have a history of not necessarily under delivering and overpromising, but really aiming for the stars when it comes to innovations. He usually gets about 80, 90% of the way there, so we’ll see how this goes.

Jon Quast: What’s interesting to me is that at some point in the last year or so, we stop measuring AI compute with GPUs. We switch to measuring it by how much power is needed. We’re normally talking about gigawatts or if you’re a back to the future fan a gigawatt, but Terafab is looking at a terawatt of compute power annually. Rachel, I just want to underscore that. This is a huge number.

Rachel Warren: Yeah, so gigawatts is 1 billion watts. A Terawatt is 1 trillion watts. This is a massive leap that almost no one else is currently baking. To put it in perspective, a single terawatt is about the total power capacity of the entire US grid. Basically, this is a bet that the future requires a nation’s worth of computing power run things like Tesla’s global robot fleets and orbital AI networks. But I think it is important to put some of this in context. Really the effectiveness of Terafab is going to really depend on whether Musk can solve the task of entering a field, semiconductor manufacturing where his companies have zero experience. There’s been a lot of critics and industry experts that have come out saying, this plan is virtually impossible. Chip fabrication is vastly more complex than building cars or rockets. It requires atomic level precision that takes decades to master. Some people have pointed to Tesla’s 46 80 battery cells as a cautionary tale. This was a project that promised to revolutionize energy, but faced years of delays and did not meet its original performance targets. Of course, we have seen Musk bring his scale of innovation and I think surprise the NASARs many times before. A lot to watch here. It is certainly a very interesting bet on the future of semiconductor manufacturing, and I think investors will be excited to watch what happens coming next.

Jon Quast: Yeah, we definitely don’t know when it comes to the timetable or the scale, just how well Musk will deliver on his promises here, but we will be keeping an eye on it because he’s definitely moving in that direction. It could really be an interesting thing to watch. When we come back, we’re talking about some of our favorite investing trends. You’re listening to Motley Fool Money.

Mark Kistler: Every Sunday, we talk about the week’s tech news on This Week in Tech. Hi, this is Leo Laporte. Inviting you to join me this week with Lisa Schmeiser, Dan Patterson, and Janko Regers. We’re to talk about the new 49 megabyte webpage. It’s the standard. We’ll also talk about Elon Musk. You’ve got some splening to do and the Yasi Flter new from Invidia. That’s this week on This Week in Tech. You’ll find it at twit dot TV or wherever you get your podcasts.

Jon Quast: Welcome back to Motley Fool Money with the Hidden Gems team. We’d like to use this Monday episode of the podcast to talk about some of our favorite investing principles on the Hidden Gems team. On previous episodes, we’ve talked about things like overlooked components of the business that make a difference. We’ve talked about leadership teams. Today, we want to acknowledge that we like big picture growth sectors. We like secular growth trends. Maybe it goes without saying, but why do we look at this when we are looking for stocks to invest in?

Matt Frankel: Think back to some things that are now commonplace in our everyday life that were major trends not too long ago. Things like software as a service and smartphones are even. I can even remember back to when ecommerce really was an early stage trend. I’m aging myself a little bit there. There were some generational wealth creation opportunities in those days, and most of which are really only obvious in hindsight. Amazon was not Amazon. It was the best time to invest in it and in the moment, they were far tougher to spot. It’s a nice challenge and by acknowledging and studying the trends today that are in the earlier stages, we can set ourselves up to find tomorrow’s big winners.

Rachel Warren: Yeah, when you focus on secular growth trends, it’s very much a tailwind that can carry a company forward, regardless of what the broader economy is doing. Think of transformative shifts like the rise of AI, the shift to renewable energy, aging global populations. When you’re investing in these mega trends, you’re betting on a fundamental change in human behavior or technology that’s likely to last for a decade or more, and a lot of those trends really provide a stable foundation that can help investors weather portfolio, and market shifts. It also really allows you to ignore the noise of market cycles and focus on compounding returns through companies that are capturing value in really fast growing sector.

Jon Quast: This is for each of you. Let’s not just talk about big trends in theory. What are some trends that you believe will experience incredible growth over the next ten years, and which ones do you love most today? Matt, let’s start to you.

Matt Frankel: One of my favorite trends to watch is quantum computing, but it may be a little early to effectively invest in. I think if you were to invest in ecommerce like five or six years before it was actually possible to do ecommerce. I’m closely watching IBM. That’s the company that I’m using as, like, my gauge here as an early quantum play. It’s not only the furthest along when developing viable quantum computing hardware, but the company has consistently met its development milestones well ahead of schedule. Arguably the biggest question in quantum computing is when will it be commercially viable? Depending on who you ask, there’s like a 10 year window when it could finally reach an inflection point. I’m watching for clues when that might happen as we get a little bit closer.

Rachel Warren: I’m really excited by the rise of physical artificial intelligence, which is basically advanced software moving and acting in our world rather than just staying inside a screen, you can see this happening right now in health care with surgical robotics. These systems are acting as a super human partner for doctors, particularly with the advent of AI, offering precision, simply isn’t possible for a human alone. I think it’s a much larger move towards personalized medicine. Our technology helps tailor every treatment to patients specific needs. There’s a few companies I watch in this space. Obviously, Intuitive Surgical is a big name here. Their systems are already used in millions of robotic assisted procedures, but you’ve also got major players like Medtronic and Johnson and Johnson. I think it’s a really fascinating space to watch. Again, we’re looking at companies that aren’t just selling a piece of equipment once, but are creating a whole ecosystem of specialized tools and services that generate steady revenue. A lot of exciting things happening in healthcare.

Jon Quast: Those are a couple of good trends. Personally, I like domestic manufacturing and that trend, but unfortunately, we don’t have time to talk about that today. Matt and Rachel, thank you so much for sharing your thoughts. I need to say the disclosure, and that’ll be the end of today’s episode. Thanks for joining us.
