I had a very bad month closing down 10.17%.
There was no rapid drop was a slow and painful bleed this month.
The big problem this month was the absence of any big winner. My biggest was less than a 1% portfolio gain. By comparison my biggest loser was nearly a 2% portfolio loss. Most months I'll have a big gain that will be a 3-4% portfolio gain, which takes care of a lot of small losses.
I also had a few trades that were bigger losses than I should have had. I should not have been taken 1% losses without the winners. I need to concentrate on keeping the losses small and letting some winners grow.
