A year ago, Rebecca purchased 100 shares of Havad stock for $25 per share. Yesterday, she placed a limit order to sell her stock at a price of $30 per share before the market opened. The stock’s price opened at $29 and slowly increased to $32 in the middle of the day, before declining to $28 by the end of the day. The stock did not pay any dividends over the period in which Rebecca held it. What was Rebecca’s return on her investment?
