What's your point BS ?? Virtually the whole of Britain has been working from home since March last year and we have experienced a plummeting share price !!
all sounds good stew but we are one year down in the most favourable climate in which this company can prosper and the share price has plummeted. Forget the theory for a minute and look at what has happened in practise.
BG's charges just come out the fund, probably accrued on a daily basis - this then gives you the fund's NAV. Whatever the share price is relative to the NAV is the premium/discount.
