MWR is what we investors truely make from our money in the market.
TWR is just a way to sell the notion that it "removes cash inflows and outflows".
Sub-periods of negative returns will make TWR larger than MWR.
Hence, with a longer track record for professional portfolio managers, the gap between TWR and MWR actually widens over time as most are unable to beat the market index.
On the other hand, large positive returns will narrow the gap, especially so when you buy more during crashes. In such cases, MWR will outpace TWR.
The best investors tend to have a higher MWR than TWR as they buy the dips, so good job for you.
Ok, now I understand why TWRR is preferred by fund managers.
Because their clients will panic withdraw/redeem funds during dips, and then at the slightest sign of some rally, they start to sell (and after long rallies, only then start to buy more). These cash in/out is not stored in with the fund manager so will significantly hurt the fund manager's MWRR.
Whereas investors managing own funds will buy the dips/crash and then sell only after long rallies. And for myself, all the cash to buy or sell still stay in my broker account, not cashed out immediately!
I use IBKR as pseudo savings account since they pay higher interest on cash than SG banks.
So basically, MWRR for retail investors managing own portfolio. TWRR not needed. If TWRR is smaller than MWRR, it isn't a problem for retail investors, as long as TWRR is still higher than chosen benchmark.
Yeah, Adam Khoo should report MWRR since he is managing own money and not a fund manager subject to untimely client redemptions.
