Capital Appreciation
  
Yes, we all appreciate having capital. But this term applies when the value of capital goes up or, well, appreciates. Important note: you don't have to do anything for capital to go up in value. Let's say you buy a stock for $20, and after a year its value is $25. It has appreciated $5 a share. You didn't have to do anything, and you don't have to sell, trade, or do anything now. You can just sit back and appreciate the appreciation.
