Oppenheimer Inc. just paid a dividend $($D$0)$ of $$3\mathrm{.}00/$share$.$ The firm's dividend payment is expected to undergo fast growth for the next five years in a row at $75\%$ each year $($between t $=0$ and t $=5)$; then the firm's dividend will grow at $25\%$ each year for $5$ more years $($between t $=5$ and t $=10)$ until it slows down to a permanent growth rate of $5\%$ per year forever. Required rate of return $($discount rate$)$ for equity is $12\%.$Based on the dividend discount model, how much should the company's stock $($per share$)$ be trading at$?$
