mmWave

• The Bottom Line: mmWave is the ultra-high-frequency, lightning-fast lane of the 5G highway, but for value investors, it's a critical case study in separating technological hype from long-term, profitable reality.
• Key Takeaways:
• What it is: mmWave (millimeter wave) is a band of radio frequencies that delivers incredibly high data speeds but has a very short range and is easily blocked by obstacles like walls or even leaves.
• Why it matters: It requires massive, ongoing capital_allocation from companies to build out the necessary infrastructure. This can either unlock tremendous future value or become a “capital black hole” that destroys shareholder wealth. It's a test of management's discipline and a potential source of market mispricing for the patient investor.
• How to use it: Instead of betting on the technology itself, a value investor should analyze the entire ecosystem—from spectrum holders to tower companies and chip makers—to identify which businesses have durable competitive advantages and can generate predictable cash flows from this technological shift.

Imagine the internet is a water system. For decades, most of us have been getting our “internet water” through pipes of a certain size. 3G was like a garden hose. 4G/LTE was a significant upgrade, like the main water pipe coming into your house—reliable and with good pressure, enough for most daily needs. Now, enter 5G. 5G isn't a single new pipe; it's a whole new plumbing system with three different types of pipes, and mmWave is the fire hydrant. When you open a fire hydrant, you get a massive, overwhelming blast of water. It's more powerful than anything else in the system. That's mmWave. It can deliver breathtaking speeds, allowing you to download a full-length 4K movie in seconds. It's the technology that promises to power futuristic applications like real-time augmented reality, autonomous vehicle communication, and smart cities. But here's the catch, and it's a big one for investors. This fire hydrant has two major problems:

• It has terrible range. The powerful blast of water peters out to a trickle just a block or two away.
• It's easily blocked. The slightest obstacle—the wall of a building, a tree, heavy rain, or even your own hand covering your phone's antenna—can stop the flow completely.

To make this “fire hydrant” network useful, you need to install one on nearly every street corner, in every stadium, and inside every large building. This is phenomenally expensive. So, while the technology is impressive, the economics are daunting. For a value investor, the question isn't “Is mmWave cool?” The question is, “Who will actually make a durable profit from building and using it, and at what price am I willing to invest in that prospect?”

“The key to investing is not assessing how much an industry is going to affect society, or how much it will grow, but rather determining the competitive advantage of any given company and, above all, the durability of that advantage.” - Warren Buffett

This quote is the perfect lens through which to view mmWave. The societal impact could be huge, but the investment returns are far from guaranteed.

A value investor's job is to cut through the noise and focus on business fundamentals. mmWave technology is a perfect example of where this mindset is essential. It's not just a new feature; it's a massive, industry-shaping capital investment cycle. Here’s why it's a critical topic for value investors:

• A Masterclass in Capital Allocation: Companies like Verizon and AT&T are spending tens of billions of dollars on mmWave spectrum and equipment. A value investor must ask: Is this a prudent use of shareholder capital? Will it generate a satisfactory return_on_invested_capital over the next decade? Or is management simply engaging in an expensive arms race, forced to spend heavily just to keep up with competitors, with no real long-term advantage? Analyzing a company's decisions around mmWave provides a clear window into the quality of its management and their commitment to long-term value creation.
• The Search for a Durable Moat: A competitive_advantage, or “moat,” is the cornerstone of value investing. Does owning a large swath of mmWave spectrum create a lasting moat? On one hand, spectrum is a finite, licensed asset, which is a barrier to entry. On the other hand, if the cost to make it usable is astronomical and competitors have a “good enough” network with other, cheaper bands of 5G, the advantage may be minimal. An investor must analyze whether this technology strengthens a company's moat or simply deepens the capital quicksand it must wade through.
• An Opportunity in the Hype Cycle: New technologies are often accompanied by extreme market sentiment. At first, there's euphoria, and any company associated with mmWave sees its stock soar. Later, when the challenges of deployment and monetization become clear, disillusionment sets in, and those same stocks may be unfairly punished. This is mr_market at his most manic-depressive. The rational value investor ignores the hype and the despair, waiting for moments when the market price becomes disconnected from the long-term intrinsic value of the underlying businesses.
• The “Picks and Shovels” Perspective: During the gold rush, many prospectors went bust. The people who made the most consistent fortunes were those selling the picks, shovels, and blue jeans. The same principle applies here. Instead of trying to guess which telecom carrier will “win” the mmWave race, a value investor might find better, more predictable opportunities in the companies that supply the entire industry. This could include cell tower REITs, fiber optic cable providers, specialized semiconductor manufacturers, or testing equipment companies. These businesses can often thrive no matter which carrier gains market share.

Analyzing mmWave isn't about becoming a radio frequency engineer. It's about applying a disciplined investment framework to a technological trend.

1. Step 1: Deconstruct the Value Chain. Before analyzing a single company, map out the entire mmWave ecosystem. Who are the key players at each stage?
   • Spectrum Holders: The telecom carriers (e.g., Verizon, AT&T) that buy the licenses from the government. They bear the biggest direct cost and risk.
   • Infrastructure Providers: Companies that own the physical assets. This includes cell tower companies (e.g., American Tower, Crown Castle) that lease space, and fiber optic network operators that provide the backhaul ¹⁾.
   • Equipment Manufacturers: The “picks and shovels” companies that build the network hardware, like base stations and antennas (e.g., Ericsson, Nokia).
   • Component Suppliers: The companies that make the crucial chips and processors that go into both the network equipment and the end-user devices (e.g., Qualcomm, Qorvo, Skyworks).
   • End-Device Makers: Companies like Apple and Samsung that make the phones and other devices that use the network.
2. Step 2: Follow the Money (Focus on Cash Flow). For any company you analyze, ignore the rosy revenue projections and dig into the financial statements.
   • For Carriers: Look at their Capital Expenditures (CapEx). Is it rising dramatically? How are they funding it—with debt or operating cash flow? Most importantly, is there any evidence yet that this spending is leading to higher average revenue per user (ARPU) or new, profitable revenue streams?
   • For Suppliers/Infrastructure: Look for revenue visibility and customer concentration. Do they have long-term contracts? Is their technology essential and difficult to replace? A tower company with 10-year leases with built-in price escalators is a fundamentally different (and often more predictable) investment than a carrier spending billions in the hope of future returns.
3. Step 3: Assess the Moat of Each Player. Using the value chain map, evaluate the competitive advantage of each business.
   • A carrier's moat might be its brand and scale, but it's constantly eroded by price wars.
   • A tower company's moat is its physical location; you can't easily build a new tower next to an existing one. This is a powerful, real-estate-like advantage.
   • A specialty chipmaker's moat might be its intellectual property and patent portfolio.
4. Step 4: Demand a Margin of Safety. The future of mmWave is highly uncertain. Its adoption rate, profitability, and the “killer apps” that will use it are all unknown. Therefore, any investment in a company heavily exposed to mmWave must come with a significant margin of safety. This means buying the business at a price well below your conservative estimate of its intrinsic_value. This discount protects you if the rosy future takes much longer to arrive than expected, or never arrives at all.

Let's compare two fictional companies to illustrate the value investing approach to the mmWave ecosystem.

• Company A: GigaSpeed Telecom Inc. - A major wireless carrier that has spent $20 billion on mmWave spectrum and has publicly committed to another $30 billion in network buildout over the next five years. Their marketing is all about being the “fastest network on the planet” and future revenues from autonomous cars and the “Internet of Things.”
• Company B: Urban Connect REIT. - A Real Estate Investment Trust that owns thousands of “small cell” locations—utility poles, rooftops, and streetlights in dense urban areas. They sign 15-year, non-cancellable leases with multiple carriers, including GigaSpeed, who need to install their mmWave equipment on these structures.

Let's analyze them through a value investor's lens:

Conclusion: A value investor might be wary of GigaSpeed. The story is exciting, but the path to a profitable return on its enormous investment is fraught with uncertainty and competitive pressure. Urban Connect, while far less glamorous, presents a much more attractive profile. It has a clearer moat, more predictable cash flows, and benefits from the overall growth in data demand without having to bet on which specific technology or carrier will win. It is the quintessential “picks and shovels” play.

This section refers to the pros and cons of using mmWave as a central theme in your investment analysis.

• Highlights Management Quality: Analyzing a company's mmWave strategy is a powerful litmus test for management's discipline and long-term thinking on capital_allocation.
• Identifies Market Mispricing: The extreme hype and subsequent disappointment surrounding technologies like mmWave often create opportunities for patient investors to buy good businesses at fair prices, or even great businesses at wonderful prices.
• Focuses on Business Fundamentals: A proper analysis forces you to look beyond the exciting technology and focus on what truly matters: competitive advantages, cash flows, and returns on capital.

• Risk of Entering a “Value Trap”: A telecom company might look cheap on paper after its stock has fallen, but it could be a value_trap if it is forced to continue pouring capital into a low-return mmWave network for years to come, permanently impairing its intrinsic value.
• Requires a Circle of Competence: While you don't need to be an engineer, you need to understand the basic business dynamics of the telecom and tech industries. Investing without this basic understanding is pure speculation.
• The “Story” is Seductive: It's easy to get caught up in the narrative of a transformative technology. Investors must be vigilant in grounding their analysis in numbers and economic reality, not in exciting keynote presentations. The biggest pitfall is paying for a story that has not yet—and may never—translate into actual cash profits.
