Will Stocks that go up must come down ?
According to investopedia
The laws of physics do not apply in the stock market. There is no gravitational force that pulls stocks back to even. Over ten years ago, Berkshire Hathaway’s stock price went from $6,000 to $10,000 per share in a little more than a year. Had you thought that this stock was going to return to its lower initial position, you would have missed out on the subsequent rise to $70,000 per share over the following six years.
