Sometimes, the market is driven more by investor sentiment than actual fundamentals, and a melt-up is this concept on hyperdrive. Although many will say that the primary driver of a melt-up is an excess of "fear of missing out" (FOMO), there are other drivers of a melt-up that are just as important. So, what causes a melt-up and how can you avoid getting caught up on the downside of one? Let's break it down below.
Understanding melt-ups
A melt-up occurs when investors rush into the market, driving up stock prices at an unsustainable pace. In many ways, a melt-up has all the hallmarks of a bubble, yet it is a bubble created at a breakneck speed. This surge is often triggered by low interest rates, excessive optimism, or a lack of better investment alternatives. Unlike normal run-of-the-mill bull markets, where rising stock prices reflect improving corporate performance and economic conditions, a melt-up is primarily driven by emotional and psychological factors.
One of the most recent melt-ups is the run-up to the 2008-09 financial crisis, where housing prices soared as banks issued risky subprime mortgages to unqualified borrowers. Fueled by easy credit and speculation, real estate values climbed rapidly, with many believing the market would never decline. When borrowers started defaulting, the bubble burst, triggering a severe market collapse.
Why melt-ups matter
Investor behavior and risk
If you have ever traded stock, you might be familiar with the concept of stock patterns, such as a cup and handle pattern. These are patterns that will appear over time and are a reflection of common market sentiment when trading stocks. A melt-up reflects a high level of speculative enthusiasm, where investors focus more on potential gains than on actual company performance. This creates an environment where overvaluation becomes common and price-to-earnings ratios reach unsustainable levels. Investors caught up in the excitement may fail to recognize the risks, leading to sudden losses when the market corrects.
Economic and market consequences
Melt-ups can distort financial markets by disconnecting stock prices from economic fundamentals. For example, one of the most famous cases of a melt-up where investors who came in later got burned was the meme stock craze of 2020 and 2021, when GameStop (GME -1.18%) and AMC (NYSE: AMC) were driven up purely on speculation derived from Reddit (RDDT -0.21%) posts. When the market is eventually corrected, it lead to a rapid decline in the stock, which left many individuals holding the bag.

The dot-com melt-up that eventually turned sour
One of the most famous melt-ups occurred in the late 1990s dot-com bubble, which is also one of the most studied melt-ups in history. Investors poured money into technology stocks, driving the Nasdaq Composite Index to an all-time high of 5,000 points in March 2000. Just a dot-com by the name of a company would drive sky-high valuations regardless of the company's underlying metrics.
Companies with no earnings or clear business models saw crazy valuations and money pouring in. FOMO drove investors to push stock prices far beyond their intrinsic value, creating an unsustainable market frenzy. When reality caught up, and the bubble burst, the Nasdaq lost almost 80% of its value over the next two years.
