Please use the following data to answer the questions. The ticker symbols are for Tesla Inc (TSLA), Barrick Gold Corporation (GOLD) and Apple Inc (AAPL). The prices shown are the closing stock prices for the date shown. Your first task is to compute the monthly holding period returns for each stock for each month, using the Holding Period Return formula, which is HPR = (P₁-P₀)/P₀, where P₁ is the end of period price and P₀ is the start of period price. Be very careful to not mix up your dates. After you have computed the HPRs, then answer the following ten questions.
