If only we knew the answer, Tilly.
I have been surprised at the size of the recovery given that Covid is still a growing problem across the world, some sectors of the economy may take years to recover (or may disappear soon), post-Brexit trade talks have been adversely affected, and there are economic fall outs with China. Maybe I'm naturally cautious but I think there is a risk of another fall in markets if Covid spikes again here and abroad- another lockdown over the winter would be a disaster economically.
But where else is there to put funds- e.g. pension pot. Interest rates are paltry. I'm starting to favour spending more of it now than I'd planned
