Epizyme (EPZM), which ended its first day of trading Friday up 40% from its initial $15 price, briefly broke the $30 mark on Monday before ending the day +21.75%. It's the third biotech IPO to quickly grow 50% since April, the others being Chimerix (CMRX) and Omthera (OMTH) - in the latter case due to the quick buyout offer from AstraZeneca.
