发帖数: 5829 | 1 Modern financial economics is built on a foundation of sands by assuming
stock market follows random process.
Key point: if stock market price really follows a random process, you can
never make a prediction at certain point of time, the simplest version: a
random walk so up or down is always 50:50, so stock market is a casino, and
if you gamble on the market you will be wiped out eventually.That's what
financial economics and efficient market hypothesis tell you, and they are
very wrong.
