Ann: HM1 Results Announcement 31 December 2021, page-3

Don't know why it went up
The result was poor and it has only gotten worse recently with NTA at $3.38 Mon vs $3.81 at 31/12 - a drop of 12% in less than 2 months (probably even worse after this week)
The dividend commentary was probably a catalyst for the increase but if the NTA keeps declining the gains from the divi will be wiped out by a week or two of capital losses.
Uncertainty in Ukraine and the threat of interest rate rises will probably see their tech/growth focussed portfolio struggle for a while.
I do like this fund and the charitable focus so hope it works out well longer term but the market is a mean and nasty place at the moment
