I believe the firm had a reverse split back in November 2015, and it was a massive one (something like 1/1000). Fortunately for me, I wasn't invested in the firm until a full year after that.
I've been burned by reverse splits before, the worst being Citibank about 6 years ago... :p
Insult to injury for me was the 'processing fee' I got charged for the cashing out of fractional shares after the reverse split, which was always more expensive than the value of the fractional share.
