If I tell you that an investment returns 16%, 5% of the time, are you able to calculate the standard deviation with this information, or is more required?
If I tell you that an investment returns 16%, 5% of the time, are you able to calculate the standard deviation with this information, or is more required?
You have to specify how close it is to 16% for that 5% of the time. Do you mean there is a 5% chance the return will be between 15.5% and 16.5%?? Do you believe the distribution to be symmetric around 16%?? Looks like a normal distribution?? If you made those assumptions, you could get an estimate of the standard deviation.
