Ok, CAGR is 5.5%.
The probability of it fluctuate between 2 sigma is 95%.
Which means: the probability of the return dropping to -59.5% or worse is (100% - 95%)/2 = 2.5%.
Yes you are right however I did not include this minor detail in because I believe for a UTF to hit more than 2 times SD is very remote. The probability of it fluctuate between 2 sigma is 95%.
Which means: the probability of the return dropping to -59.5% or worse is (100% - 95%)/2 = 2.5%.
For more nitpicking detail: If you take the more than 2 SD into consideration, the chances of this happening in a three year tracking period is about 55 days i.e., in a 3 years (1,095 days) period you make the observation, the chances of the NAV go outside the band of +70.5% or -59.5% will not be more than 55 days in total.
That means if the fund really go to that level, it will very quickly move back towards the mean.
