### The Case of The Accidental Double, Triple, Quadruple, Quintuple

On 19 December 2003, Zelmo Zeroman accidently bought some Red Hat (RHT) stock at \$16.87 per share. He decided to hold onto the shares because he believed Red Hat as a good long term investment. It took almost seven years for the accidental buy to double. At the of 2015 the RHT shares had increased by a multiple of five.
