Market bubbles are common but dangerous from "summary" of A Random Walk Down Wall Street by Burton Gordon Malkiel
Market bubbles are like the sirens in Homer's Odyssey. They sing a song of profit that can lure investors to their doom. These bubbles are created when the price of an asset – whether it be stocks, real estate, or tulip bulbs – becomes detached from its intrinsic value. Investors start buying not because they believe in the fundamentals of the asset, but because they believe they can sell it at a higher price to a greater fool.
History is littered with examples of market bubbles. The most famous is probably the Dutch Tulip Mania of the 17th century. At the peak of the bubble, a single tulip bulb could fetch a price equivalent to a luxurious house in Amsterdam. Then, just as suddenly as it began, the bubble burst, leaving investors destitute and tulip bulbs worthless.
But it's not just tulips that can become the subject of a speculative frenzy. Stocks, real estate, and even cryptocurrencies have all experienced their own bubbles. The dot-com bubble of the late 1990s saw investors throwing money at any company with a ".

The dangers of market bubbles are clear. When the bubble bursts, investors can suffer catastrophic losses. But the damage isn't just financial. Bubbles can also have far-reaching consequences for the economy as a whole. The housing bubble of the mid-2000s, for example, led to the global financial crisis of 2008, which saw millions of people lose their homes and their jobs.
Despite the risks, market bubbles continue to occur with alarming frequency. Part of the problem is human nature. The same psychological biases that lead us to buy high and sell low also make us susceptible to the allure of market bubbles. Greed, fear of missing out, and herd mentality all play a role in inflating bubbles to unsustainable levels.
So how can investors protect themselves from the dangers of market bubbles? The key is to focus on the fundamentals. Instead of chasing hot stocks or assets, investors should do their due diligence and invest in companies with solid earnings and growth potential. They should also diversify their portfolios to spread risk and avoid putting all their eggs in one bubble-shaped basket.
In the end, market bubbles may be common, but they are also dangerous. By staying grounded in reality and resisting the siren song of easy profits, investors
