Can someone explain the sector allocation of the fund will help diversify the total portfolio hold by fund manager? for context the fund is M&G SA EQUITY CLASS F with benchmark of SATRIX $40$ ETF, we have other ETF in portfolio which is iShare Core S&P$/$ASX $200.$ Does the weight allocated differently on each sector from m&g and ishare contribute to diversification? for example $5\%$ on material in m&g and $10\%$ on materials in iShare. Also they have different top holding such as technology. in ishare there's no technology company but they have it on m&g mutual fund.
