It looked like someone liquidated a non-trivial amount of shares on March 3. I bought some from whomever it was selling, and am already up a fair amount on today's bounce.
I did see a new 5% position by Birmingham Capital disclosed today. But could that cause such a big move?
Why the +18% after hours move? It's earning season, but I didn't see a press release reporting results yet, even on the SQBG Investor Relations page.
