I think the issue is that they position themselves as passive investments and ETFs. I quote below from the Stashaway website.
"StashAway recognises that data has proven that securities selection has not been paying for itself over the last decade, particularly in the largest, most transparent markets. In this respect, StashAway is a convinced passive investor when it comes to securities selection, in that we don’t spend money and time with securities selection, but rather invests through ETFs in the entire “market”."
Some of my active managers are also down but at least compared to the benchmark they are down less and they don't do noob things like sell at the absolute bottom when if they waited 2 more days, they would have recovered at least 20% of the loss. As someone mentioned, you pay for what you get.
