thanks for taking interest in this....
I was discussing about the need to do capital injection to try to raise the IRR....
my maths was trying to shows that, without actual capital injection and by just doing some moving around of funds, the IRR can moves.....sort of refer to post# 480
"IF" Irr values can be "played" by that,.....then frequent traders "may" have a better performing IRR.
I think you are being kind to my long, grandpa post eventhough it looks gibberish to you.
Seriously, at least try to read it again... as what I was saying is using IRR as a measuring gauge in another manner - to gauge the past recent history of your portfolio performance.
Just as we can look towards the future in short term as well as long term viewpoint, we can also look into the past performance history in terms of recent history as well as deeper history.
Why do you need to have maths to prove something that is already known? Common sense already tell us that UT funds are volatile. Even if we do nothing to the portfolio, the ROI (and indrectly, the IRR) will move along with the volatility of the portfolio. Of course, there would be added movement whenever we adjust and fiddle with the portfolio by switching from one fund to another, or one category to another.
Look, IRR is just an 'effective rate'. It is for having an apple to apple comparison. For example, banks can have a FD promotion with step up rates from 3.5% to 4.8% on every subsequent 3-months deposits. At the bottom of the brochure, the "effective rate" would be stated too. This "effective rate" is the actual interest rate if the deposit is only withdrawn at the maturity date 12-months later.
So, to compare whether the step-up FD promotion is better than another bank's FD promotion, we just need to compare their "effective rate".
In that previous post, the last part is on doing IRR on the current porfolio without back dating it to Day1 of your investment adventure. I put that into the post because you will eventually need the IRR (or the "effective rate") after monitoring the yearly growth for a few years.
Each year will have a different growth rate - just like in the step-up FD promotion every 3 months. This is the reason to have IRR - to have an "effective rate" to make comparison on the returns of the current portfolio against FD and/or EPF rates.
Lastly, the phrase, I think, you were looking for is not 'creative accounting' - which is lying using numbers. It is 'playing with numbers' - meaning fiddling with several options/scenarios and asking lots of what ifs. For example, what if the bond ratio in the portfolio is adjusted from 45% to 50%, what if equity fund A is increased from 5% to 8%, etc. etc.
"IF" Irr values can be "played" by that,.....then frequent traders "may" have a better performing IRR."No, IRR cannot be "played" like that, As explained, it is only an "effective rate".
What was being played around is the portfolio - by trading (moving funds in and out by selling and buying them), and switching from one fund to another. How frequent you turn the portfolio around - which can be called "portfolio turnover" as in "inventory turnover" - will definitely affect the returns (which is the ROI, and the IRR too) -
for better or for worse.
