Match each of the following behaviors with the appropriate bias as discussed in the chapter.

a. Wanda owns Happy Clam Oil Exploration, but due to recent events, the share price is down 30 percent from when she bought it. She doesn't want to sell now because it had previously been up as much as 25 percent.

b. Drew doesn't believe his friends who tell him that he cannot time the market. He has been successful in making profits from his trades this past month and plans to continue his day trading.

c. Yusuf has been watching the gold market go up and up, so he decides that since everyone is buying gold he needs to do so as well.
