How swiftly can you process your emotions?
Stocks trade on exchanges. Because dividends are either small or nonexistent, the value of your stock is determined solely by what other investors are willing to pay for it. In a calm market, you will experience a sense of unmanageability, because there is nothing you can do to force others to raise the price of your stocks. Even small losses in calm markets can be troubling because investors rarely want to admit their mistakes, feel the pain of loss, and move on. Focusing on prices rather than the cause of the losses, they hang on to losers until they can break even.
Optimism can grow into fantasy. Investors sometimes fall in love with their companies. They fantasize about new products and skyrocketing stock prices. All evidence of deteriorating fundamentals is rationalized away or ignored. Individual stocks can decline for years or decades. Believing fantasy can lead to many years of pain even in calm markets. However, we have seen few calm markets in recent years, and volatile markets are more troublesome.
In most markets, stock losses happen quickly. A bad earnings report can cut a stock price in half. An unexpected rate hike by the federal government can knock the whole market down 15 percent in a month. For still unexplained reasons, the whole market dropped 22 percent on October 19, 1987. Few investments move so quickly. Real estate rarely moves 1 percent a month. Unless you can process your emotions quickly, stocks will cause you a lot of pain.
