Explain the term Survivorship Bias and how it impacts the evaluation of the investment returns of a group of portfolios.
Survivorship
biased- Survivorship biased means to show the funds
performance of existing fund in the market as sample shown to the
investor who wants to invest in the market. They do not show the
actual picture of the market, they have to manipulate the investor
by showing only those funds which is existing in the market, they
don't show or tell them about those funds which was closed or not
doing well in the history.
This will show the overestimation picture of the Portfolios.
It will imapct the investment return of the group of portfolio
because if they invest in those portfolio which are winners today
because market are in there favour, tomorrow all there winners
portfolios are converted into loosers ones.
When we have to choose a Portfolio manager to invest in the market we have to see his history whether he has shows his all portfolio when they acheived superior return or flops in the past, if they doing a Survivorship biased, they will impact the return in near future.
I hope this clear your doubt.
