What is your cumulative holding period raw and excess return and what will be your compounded annual raw and excess returns if you you have a portfolio that changes for the period that you hold it? For example, lets say we hold 2 stocks A (price = $10, quantity = 10) and B (price = $20, quantity = 20) . We buy stock A on Monday and stock B on Tuesday. Could you please give me an excel stile answer and showing the formulas.(if additional information needed please feel free to make it up and explain why). Thank you so much.
