That's why I emphasised
started in March. As in started putting new money in in at or around the low, I think plenty of that happened.
Frankly I'm kicking myself for not doing as you say. I 'thought myself very smart' by being aware of it over the new year, reading how bad it will be, thinking markets will tank, and sticking to my guns because 'I won't try to time the dip'. And then of course with a modest amount of new money in March thought 'if I'd sold in January I'd definitely be pound cost averaging back in now, even if not piling back in, I'm an idiot for being 'sensible''.
If I had though I'd probably be thinking it's crazy at the moment (or especially a week or two ago) and piling back out... Remains to be seen how well that would've gone.
I think really it's all a good argument for separating 'boring, don't touch it, keep buying', and 'fun, dabble, hobby speculation'. Where the latter should be funded appropriately for what it is, a hobby.
