Answer whether or not the statement is True (T) or False (F), and provide an explanation (example) of why your answer is correct

(T/F) Suppose that there are 10 stocks and you have created the minimum variance frontier using these 10 stocks. Now, introduce a new stock to the portfolio. It is possible that the new minimum variance frontier created with 11 stocks (10 original stocks in the portfolio plus the new stock) is worse than the original minimum variance frontier with 10 stocks.
