refer to the following passage:

A bear market is a time when, in general, the value of stocks on the stock market is going down. A bull market is a time when, in general, the value of stocks on the stock market is going up. Over the past 50 years, approximately one out of every four years has a bear market. It is difficult or impossible for anyone to reliably predict what the stock market will do next year. In light of that information, Hadrian runs a real estate company. If he buys commercial property and a bull market happens he will probably get a profit of $500 000 over the next year. However, if he buys commercial property and there is a bear market he will lose $300 000. If instead he buys a residential building he expects a profit of $300 000 if there is a bull market or a profit of $100 000 if there is a bear market.

What should Hadrian do? If you make calculations, show your calculations. Also, give a two sentence explanation of your answer.
