Each of four siblings (Anita, Tony, Maria, and Jose) is given $5,000 to invest in the stock market. Each chooses a different stock. One chooses a utility stock, another an automotive stock, another a technology stock, and the other an oil stock. From the following clues, determine which sibling bought which stock. Anita and the owner of the utility stock purchased their shares through an online brokerage, whereas Tony and the owner of the automotive stock did not. The gain in value of Maria's stock is twice the gain in value of the automotive stock. The technology stock is traded on NASDAQ, whereas the stock that Tony bought is traded on the New York Stock Exchange.
