If you pay peanuts, you get monkeys. ~ Old adage
If you remember the stock market crash of 2008, you also remember that it spared almost no stock. Companies, even the well-managed ones, lost half or more of their market capitalization in few months.
As an example, Pidilite (makers of Fevicol), which was one of those extremely well-managed businesses then, lost 55% between December 2007 (just before the crash started) and March 2009 (the bottom). Titan and HDFC Bank, two other stalwarts, lost 50% each. In short, the crash was like a bad dream for people even in these marquee stocks.
But for those who held on to their nerves, and to these stocks, the next decade was about to turn into a beautiful dream.
As an example, assume you were owning Pidilite near its peak in December 2007 and went into a deep sleep that continued till today (June 2018). Your return from the stock would have been around 1,000% (CAGR of 26%) over this decade!
