The review frequency was itself tested by our research team. We tried quarterly review etc. but we found a one-year review has adequate data to give the best recommendations. It is also in line with what most experts suggest - review your portfolio every year.
Scripbox fund selection is not based on removing an under performing fund. Every time we select our portfolio of funds, we do the fund selection from scratch. We follow a top-down approach for fund selection, where we look at the entire universe of funds available and select the best of the lot.
