Suppose that your portfolio currently consists of two stocks: A and B. You own 5,000 shares of Stock A that is priced at $14 per share and 2,000 shares of Stock B that is priced at $27 per share. If the price of Stock B decreases from $27 to $23, how many shares of Stock A would you need to purchase (or sell) to re-balance your portfolio such that the weights of both stocks remain unchanged from the original prices?
