Undervalued or Overvalued? How to Read an Asset's Real Price
How to tell if an asset is undervalued or overvalued: fundamental and technical analysis, the macro backdrop and market psychology, explained for investors.

The most general theory of investing tells us that a good investment is made at the moment of purchase, not at the moment of sale. Put another way: there is no asset good enough that, bought at too high a price, will still hand you strong returns, and no asset bad enough that, bought at a good price, will not.
So, to paraphrase again, the quality of an asset for a portfolio is directly proportional to the price you pay for it. We have all heard the famous "buy low, sell high." But the real question becomes: how do we know when an asset is undervalued and when it is overvalued?
Identifying undervalued and overvalued markets or asset classes is one of the most critical and challenging tasks an investor faces. This skill not only helps maximize return potential but also minimizes the risks tied to any investment. Distinguishing an asset's "cost" involves a blend of art and science, combining quantitative analysis with qualitative, subjective intuition.
In this piece we explore how investors can navigate this complex financial landscape, using a range of tools and techniques to spot promising opportunities and avoid the traps set by market psychology (a topic for another day).
To ground the concepts, let's start by defining what it means for an asset to be undervalued or overvalued. In simple terms, an asset is undervalued when its current market price is below its intrinsic value, that is, the value derived from its ability to generate future cash flows, or any other measure of intrinsic worth you choose to use. Conversely, an asset is considered overvalued when its market price exceeds that intrinsic value. Which naturally leads to the next question: how do we determine an asset's intrinsic value?
Let's explore some conventional valuation tools and techniques. Although some of them may seem sophisticated, or at least uncommon among everyday investors, it is worth becoming familiar with the terminology, especially in the current stage of the markets, where both investment alternatives and these very tools are increasingly democratized. Years ago it was unthinkable that we would be a few clicks away from every financial market in the world, able to invest in them personally and at our own discretion, without intermediaries.
Fundamental analysis: the old school's favorite
Fundamental analysis is the cornerstone for assessing the intrinsic value of a publicly traded asset. This approach examines everything from a company's financial statements to its market position, competition, management and macroeconomic factors. Here are a few key tools worth understanding (the ones favored by Warren Buffett):
- Financial ratios: Ratios such as price-to-earnings (P/E), price-to-book (P/B) and dividend yield offer quick perspectives on valuation. A low P/E, for example, might suggest a stock is undervalued, though it is crucial to read that ratio in the context of the sector being analyzed and the broader economy.
- Discounted cash flow (DCF): This method estimates an asset's intrinsic value by discounting its future cash flows back to the present. I am not a fan of projections in a market this changeable, but it belongs here because it is still widely used. As a rule, if the calculated value is higher than the market price, the asset may be undervalued.
Technical analysis: increasingly used, less understood
Technical analysis, by contrast, focuses on price and volume patterns to anticipate an asset's future direction. Although some critics dismiss it as "financial fortune-telling," it can offer valuable insight when combined with solid fundamental analysis. I would add that it is very dangerous to use in isolation.
- Technical indicators: Tools such as moving averages, the Relative Strength Index (RSI) and the MACD can help identify trends and buy or sell signals. These signals should be used as complements, since they carry a wide margin of error.
- Trend analysis: Rooted in the theory of market cycles and supported by the study of market psychology, identifying support and resistance can offer clues about price levels that are psychologically significant to investors, especially in globally demanded assets such as metals, cryptocurrencies or foreign exchange.
Assessing the macro backdrop: the most complex of all
Understanding the macroeconomic context, or at least theorizing about it, is crucial for judging asset valuations, as well as how relevant those assets will or will not be in the future. Factors such as monetary policy, interest rates, inflation and economic growth can have a significant impact on the valuation of different asset classes.
If you want to move to second-level analysis, you will have to start studying theories that sound conspiratorial at first, but the deeper you dig, the more supporting information you tend to find, and you may be surprised to find your own assumptions challenged. Some of these themes touch on CBDCs, privacy, geopolitics and war, the future of democracy, and de-dollarization, among others. In broad terms, the main tools are:
- Interest rates (monetary policy): Low rates tend to lift the value of risk assets such as equities, while high rates can make fixed income more attractive.
- Economic cycles: Different assets perform differently across the economic cycle. Identifying which phase we are in can help anticipate which assets are undervalued or overvalued.
Market psychology
The influence of market psychology on valuations cannot be underestimated. Fear and greed can drive extreme overvaluations or undervaluations. They always do. Tools such as the fear and greed index (which genuinely exist) can give a sense of overall market sentiment, while a closer reading of the news can reveal how psychology is affecting specific sectors or assets.
It is almost a rule that when the vast majority of people think it is a great idea to buy or invest in something, it usually is not. If you doubt it, look back at the last time everyone, down to your great-aunt, wanted to buy Bitcoin. By that same logic, it is worth asking what will happen with any real estate market where every headline now insists that buying apartments is a sure thing, or any other example you can think of.
The ability to identify undervalued and overvalued markets or asset classes is invaluable in the world of investing, though it requires a healthy dose of doubt, second-level thinking and contrarian thinking. It calls for a balanced approach that combines fundamental and technical analysis with a deep understanding of the macro backdrop and market psychology. There are no guarantees in investing, but applying these techniques and strategies can meaningfully improve your odds of success and help you build a portfolio that is resilient to market swings.
So, how do you tell an undervalued asset from an overvalued one? At Buying America, this is exactly the lens we apply when helping international investors judge U.S. assets on price and value, not on the noise of the moment.
