I was interested in how gurufocus value investors calculate the margin of safety intrinsic value of a stock.
Currently I use a simple formula:
Equity per share (adjusted for intangible assets, inventory) + past 3 yr avg EPS * 10.
Total equity > total liabilities
ROE > 20%
Free Cash Flow yr1 + yr2 + yr3 >= 0
P/E < 15
Please chime in and share your thoughts
