Actuarial nia, finance just like touching water surface only, basic exposure
Learning via studies vs actual implementation in practice is different
As you know, during studies, learning the above ratio are by giving ideal values and example, hard to comprehend when comes to personal exposure in investment world, just graduated without much experience, kindly guide and forgive me if I asked something stupid :lol
That is where experience comes in lor! Real world data are never nice and predictable. If it is such, all the finance company would hire robot and you will be out of job even before you graduate. As you participate in the investment world, your mind is able to sieve out the noises more carefully and make better decision.

But I believe you need some data to calculate, like downside volatility to calculate Sortino ratio.
If using excel only, you also need a lot of past data and relevant market benchmark to calculate jensen alpha ratio.
Yup! Sortino needs downside volatility. If you have the set of data for for standard deviation, you may use that same set and omit the above mean to get Semi-deviation.
Use what is available to you, if the data is not available then don't use.

Not sure about Modigliani ratio, but, speaking about sharpe ratio and risk return ratio, if you see FSM, CMF has the highest risk return ratio, about 30 times as much as KGF Evergreen fund. OK, if you say we compare the metrics within the same class, that would be somehow fair comparison. However, if across different asset classes, how do those metrics bring meaningful interpretation and comparison?
Modigliani aka M2M ratio is a derivative of Sharpe ratio. And M2M-ratio can bring different classes into parity for comparison sake. Problem is that the parameters needed to compute M2M ratio are not readily available to lay investors. Perhaps if you are working for investment bank or asset management company or perhaps UTMC, you may have access to the data.

Like comparing Ponzi 2.0 and AIF, how does the metrics explained that AIF is better in risk adjusted return than ponzi 2.0 if they are different classes? Or do you rely morningstar for it?
He he he.... that is the job best left to Algozen. She can answer it better than I do
