I use a simple formula. I buy FMG, but never sell so I really don't give a rat's what the price is (unless I'm buying that day), I usually use FMG divi's to buy other stocks, but lately, I've been increasing my FMG holding because it's return is too good to ignore. I aim to get at least 10% return on any investment I make. I average the past 4 years dividends, i.e. add up the past 8 half yearly amounts and divide by 4; if that figure is more than the past year, I use the lower figure. Currently (at $21.44) based on my calculation using the past year's dividends totalling $2.08, the return is 9.7%, but I'm retired and living off my SMSF, so I can claim back the franking credits, so my return if I was buying at today's price would be 13.85%. I reckon that's not bad. Not advice, just my approach.
