Quote for the Week
Continue Reading…We deceive ourselves when we believe that past stock market return patterns provide the bounds by which we can predict the future. When we do so, we ignore the potential for future Black Swans.
The stock market has experienced relatively few of these extreme changes. And they are overwhelmed by the frequent—but usually humdrum—fluctuations that take place each day within normal ranges. For example, the Standard & Poor’s 500 Stock Index has risen from a level of 17 in 1950 to 1,540 at present. But deduct the returns achieved on the 40 days in which it had its highest percentage gains—only 40 out of 14,528 days!—and it would drop by some 70 percent, to 276. Or eliminate the 40 worst days; then, the S&P would be sitting at 11,235, more than seven times today’s level. A good lesson, then, about “staying the course” rather than jumping in and jumping out.
Financial markets, then, are volatile and unpredictable. Importantly, the markets themselves are far more volatile than the underlying businesses that they represent, which collectively account for their aggregate market capitalization. Put another way, investors are more volatile than investments. Economic reality governs the returns earned by our businesses, and Black Swans are unlikely. But emotions and perceptions—the swings of hope, greed, and fear among the participants in our financial system—govern the returns earned in our markets. Emotional factors magnify or minimize this central core of economic reality, and Black Swans can appear at any time. — John Bogle (Source)
