OPY will be adversely affected like the rest of brokerage as people put less money into equities. There will less deals done, fewer syndications, etc.
Even if OPY is not affected they will be driven down by association. Kind of like if your neighbor gets foreclosed on and your house goes down in value as well. Many are in denial thinking it's the other guy's problem but it everyone's problem.
Bottom line....OPY is over priced, high risk and has limited growth potential given its limited capital position.
