Comment on the following transactions:
a. Mort owns 500 shares of Pear, Inc. stock with an adjusted basis of $22,000. On July 28, 2014, he sells 100 shares for $3,000. On August 16, 2014, he purchases another 100 shares for $3,400. Mort's realized loss of $1,400 ($3,000 - $4,400) on the July 28 sale is not recognized, and his adjusted basis for the 100 shares purchased on August 16 is $4,800. Explain.
b. How would your answer in (a) change if Mort purchased the 100 shares on December 27, 2014, rather than on August 16, 2014?
