Using my test sample
You have 30 winners from 50 selections
30 winners, 20 losers. Avg Dividend $4.00
Expected number of winners is 1/4 = 0.25
Normalise the market to from 115% is 0.25/1.15 = 0.21739
50 Selections so multiply by 0.21739 to get the expected winners
Gives 10.87 winners expected
Expected losers is 50 - 10.87 = 39.13
Observed winners = 30 A1
Observed losers = 20 B1
Expected winners = 10.87 A2
Expected losers = 39.13 B2
Put this into excel as CHITEST =CHITEST(A1:B1,A2:B2) on get something like 0.0000005%
Are these the chances of the system continuing?
I'm very interested in hearing others thoughts
Even making the Avg Dividend like $3.00 more realistic is still giving a very very low %
