David has $10,000 worth of stocks in his trading account. He needs to cash in $1,000 worth of stock to make a purchase. He could sell shares in one stock (Jupiter, Inc.) that cost him $2,000 initially but is now only worth $1,000, or he could sell shares in another stock (Mercury Co.) that he bought for $500 but is now worth $1,000. Even though the amount of money withdrawn would be the same, which stock is he more likely to cash out?
