Part 3: How PE ratio can reveal true value?

PE: an indicator of margin of safety

Let's assume you buy a share at Rs 550 whose EPS is Rs 50. In one year, you earn Rs 50 on an investment of Rs 550, that is, a return of about 9 per cent.

You can earn 8-9 per cent risk-free returns on bank deposits as well. So, the margin of safety in this case is practically nil.

To reduce the risk, we must have a higher gap.

Thumb rule: Warren Buffett recommends this gap to be at least 1.25-1.5 per cent.

Last word: During a bull run, investors pay a high price for any and every share. So, it becomes difficult to find stocks with a high margin of safety.

It is in bear markets, as the one we are in now, that there are opportunities to spot the gems.
