Sifu, risk adjusted performance are you referring to risk reward ratio ?
YESWhen funds have different actual performances, wouldn't the funds will have more likelihood to go back to it's mid point
[The phenomenon is known as reversion to the mean effect ] value instead of the edge value of the deviation ?
YESIs there a model where the likelihood of performance be taken into consideration ? Google
Z - score or standard scoree.g risk/reward gives you no indication of probability. What if you took your $500 and played the lottery? Risking $500 to gain millions is a much better investment than investing in the stock market from a risk/reward perspective, but a much worse choice in terms of probability.
I want to specifically answer your query that has been bolded. Noobies, this is advance class material , not kindergarten syllabus , if this is too complex for you, look away and go play at the sandbox .
Let us take the Malaysian big sweep as an example. There are seven digits starting from 000 ' 0000 to 999 ' 9999 . This means that there are 10 millions tickets each consisting of RM 3.00 per piece. RM 501 will let you acquire 167 pieces of tickets. The probability of winning the lottery is 1 / 10 ' 000 ' 000 x 167 = 0.00167 % chance. This means you have 1 - 0.00167 = 99.83% chance of losing that capital.
Now let now take TA GTF as an example. The 3 year average ROI is 21.5% and a three year average standard - deviation of 13.29%. Her one year to date ROI is 34.81%. Three year average return plus standard deviation = [ 21.5 plus 13.29 equals 34.79% ] which means the current one year ROI is very near to one standard deviation . This also means that the probability / chance of it regressing to its mean is 67% and only 1 - 67% = 33% of it moving away from the mean.
Now compare this two situation, with lottery you have 99.83 percent of losing.
With TA GTF, you have 67% of it losing.
If your choice is between spending RM 500.00 on participating in a lottery draw versus participating in TA GTF , which one should you choose ?
Bear in mind , a lottery is a one time gamble , meaning for the next round , you need to add more capital . Whereas TA GTF is always a participant until you redeem your units.
