Factor tilts in the managed folios

Factor investing is notoriously complex. It would be great to hear more about the IE approach (beyond the “philosopy” sheet) as it forms a large part of the managed folios.

Mine currently has an equal measure (around 5%) of the top 5 factors. I wonder whether this will change, if you plan to tilt depending on the changing climate, like an active fund might, or whether your approach is to stick with an equal measure to each factor? There are arguments for and against approach so I would be interested to hear what the strategy is before investing much more.
