"When the weather changes, nobody believes the laws of physics have changed. Similarly, I don't believe that when the stock market goes into terrible gyrations its rules have changed"

This quote by Benoit Mandelbrot is a contrast between the laws of physics and the stock exchange. He is suggesting that simply as the laws of physics remain continuous regardless of modifications in the weather, the guidelines of the stock market stay consistent regardless of modifications in the market. He is indicating that the stock exchange is subject to the same laws of nature as the real world, and that it is not exempt from the same concepts of cause and effect. He is recommending that the stock market is not a random, unforeseeable entity, however rather a system that follows certain guidelines and patterns. He is motivating investors to look beyond the short-term variations of the market and to concentrate on the underlying principles that govern it. By understanding these concepts, financiers can make more educated choices and be much better gotten ready for the future.
