We start with the traditional indicators of valuation like the PE ratio whether it's the Shiller CAPE ratio or the traditional S&P PE ratio. And those things showed the market to be, I used the expression a year ago, lofty but not naughty. The non-Shiller PE ratio is about 23 or so today. The 80-year average is 16. So we're roughly 50% higher today. But in 2000, I think it was 32. When I started in this business as a young man in 1969 in the research department at Citibank, the bank and most of the banks invested in what were called the Nifty Fifty. Those were the 50 largest growth companies in America. And they were considered one-decision stocks. You bought them and you never sold them. And they were priced at 80, 90, 100 times earnings. And then in 1973 and 74, they went down 80, 90% and many of them never recovered. So the lesson is that even the best companies can be overpriced. And that's what we have to be careful about today. The question is not whether AI is going to be great. The question is whether the prices being paid for AI-related stocks today are justified by the future cash flows that those companies will generate. And that's a very difficult question to answer. But the traditional valuation metrics suggest that the market is expensive, but not necessarily in bubble territory. However, the concentration of the market in a few large tech stocks is reminiscent of the Nifty Fifty era and the dot-com era. And that's a warning sign. So we have to be cautious. We have to be aware that the market is priced for perfection and any disappointment could lead to a significant correction. But we also have to recognize that we could be in the early stages of a technological revolution that could transform the economy and create enormous value. So it's a very difficult environment to navigate. But we do it by focusing on the fundamentals, by being disciplined, and by not getting caught up in the hype. We look for companies that have strong competitive advantages, that are generating real cash flows, and that are trading at reasonable valuations. And we avoid companies that are priced for perfection and that have no margin of safety. That's the value investing approach. And it's served us well for over 50 years. So we'll continue to follow it.
Called the Nifty Fifty, which were considered to be the best and fastest growing companies in America. Xerox, IBM, Kodak, Polaroid, Mercy, Texas Instruments, Hulu, Packard, Coca-Cola, Avon, etc. And most of those stocks were selling at PE ratios between 60 and 90.
So to look at the Mag 7, take out Tesla, they're selling at PE ratios in the 30s. Doesn't sound so expensive to me. But that's just PE. But you can't just depend on PE. That's too simplistic. The companies are different. Their capital intensiveness is lower, their marginal profitability is higher since the product is an intellectual product rather than a piece of metal. It doesn't cost much to make the next one. So their incremental profitability is much higher. And another thing is we've never ever seen companies growing at the rates of today. You know, and I don't know the specifics, so I don't want to go there, but you hear about companies that are growing 50% a month or 100% a year or whatever it might be. You've never seen that before. And you look at AI and the progress that it has made in the last four years. Three years ago, you talk about moats, you talk about impregnability. Three years ago, most people thought software was a great industry to invest in because everybody who used computers, which was everybody, needed software. And if you had a software system that served your company and industry, it would be expensive to change. And for the most part, it was hard to figure out a reason to change. So that's a pretty good moat. More recently, people are wondering whether the whole software industry is going to go out of business because nobody writes software anymore. AI writes its own software for itself. People have to tell it what to write, but it can write it without any help. So now in that world, there's something called SaaS, software as a service, and around February 1st we had something called the SaaS apocalypse, where the great AI companies announced some coding models and everybody said that's it, the whole software industry has gone out of business. Now that's probably an exaggeration. But it's very hard to figure out these things. By the way, I want to come back to something that you asked me a long time ago and I never answered, and I don't want to leave it unanswered. How do you invest in this given all these uncertainties that I'm talking about? And you know what history has shown is that one of the greatest mistakes you can make is being not optimistic enough. And another mistake you can make is to say the future is unclear, so I can't invest. Those two things don't necessarily go together. The future is always unclear. Maybe it's more unclear than ever, but that's not a reason not to invest. You just have to invest carefully, knowingly. You have to be aware of the risks you're taking. So how to invest in AI? Like anything else, there's a spectrum. At one end of the spectrum we have ultra high possible returns with great uncertainty, and at the other end of the spectrum maybe we have somewhat lower possible returns with less uncertainty. Now all of this is more uncertain than ever, but that spectrum still exists, and so you can choose a point on that spectrum. Let me give you a couple examples. You can invest in what we call the hyperscalers: Amazon, Google, Meta, Microsoft for example. They have established businesses with moats, enormous operating cash flow. They want to get into AI. They maybe feel that they have to compete vigorously in this winner-take-all battle. But with established businesses and cash flow and some diversity of business, these are as I said before without naming names some of the greatest companies I've ever seen. So you would think that investing in them would be maybe the low-risk way to invest in AI, but if AI booms and takes off and octuples in the next three years, since they have other businesses holding back their growth rate, they're not going to be the maximum profit winners. Then you have established companies. As you said before, we don't know their profitability, their finances, and maybe they're one-product companies in the sense that they're all AI. So maybe it's harder to specify their future. But Anthropic and OpenAI for example, Nvidia, have a very high probability I think, not being an expert, a high probability of still being successful 5 or 10 years from now. They may not be the number one they are today, but they're unlikely I think to be obsoleted. So they're depending on the price you pay and its fairness, they may be riskier than the hyperscalers, but they're not make it or break it. They're already up and running. And then you have startups where you don't know where they may not have revenues. They may have revenues but no profits. You may not even know what the product will be, but if you can get in at something called ground level and they turn into a big winner, you can make an incalculable amount of money. And I described this in a recent memo as a lottery ticket. And so at the riskiest end of the spectrum, you have lottery behavior. If you think about the lottery, most people who buy lottery tickets lose all their money. A few people become incredibly rich. So that's probably the profile of performance at the riskiest end of the spectrum. You can pick where to play on the spectrum. You can mix positions on the spectrum. And then you can decide how much of your total portfolio should be in these companies on the spectrum.
