This is a great company and an underpriced stock. Buy on pullbacks.
This week's decline on no news makes no sense. With more retirees needing more financial planning and with turbulent markets where buying-and-holding indexes has led to poor performance, good financial companies will do well. (My clients are earning 4 times the market return this year and twice the market return over the past 8 years.)
Oppenheimer has no part in the mortgage market, to my knowledge, other than in some portfolios that some less intelligent clients may have purchased. So the markets will wake up to their ignorance once they see continued growth in revenues and income.
Then it's off to the races again with OPY. GO OPY GO!
