Big drop in AFOP - no news?

AFOP is down 8.5% this morning with no news, other than a brief press release about a supplier award they received. Volume is quite large for this time of day at about 70% of daily average.

The only thing I can find for a reason is that it’s down in sympathy with FNSR. It’s also gone on a big run over the last couple of weeks and we may just be seeing some profit taking.
