so enlighten this idiot (don't worry no offense was taken) in how you buy stocks.
I wasn't calling you and idiot

Follow this system which has been proven by BEN GRAHAM and I will almost guarantee you will outperform any fund manager. But as always, do your OWN research.
A stock must pass 1 VALUE & 1 SAFETY criteria.
-------------------
VALUE
1) Earnings Yield [Inverse of PE Ratio] minimum = 2 x High Quality Bond yield
2) Current PE Ratio must be less than 40% of highest PE Ratio of last 5 years
3) Current Dividend Yield must be at least 2/3 x High Quality Bond yield
4) Current Market Cap must be less than 2/3 x Tangible Book Value
5) Current Market Cap must be less than 2/3 x Net Current Assets
-------------------
SAFETY
1) Total Debt must not exceed Book Value
2) Current Assets must be at least 2 x Current Liabilities
3) Total Debt must be less than 2 x Net Current Assets
4) Earnings Growth for 10 years = 7%pa Compound [i.e/ approx doubled over 10 years]
(Must take inflation into account)
5) Earnings must be stable over last 10 years [Less than 2 times when earnings fell by 5%]
-------------------
EXTRA (My own person criteria)
1) Must have Stable Dividend payments for last 5 years
2) Dividend increase each year for the last 5 years
