*ECONOMICS* Which speaker is most likely to make diversified investments?

Speaker A: I want to invest in a lot of different companies. You never know
when a company is going to have a surprisingly good or bad year.

Speaker B: I invest to get as much money as I can as quickly as I can. I'm not
worried about losing money at all.

Speaker C: I'm nearing retirement, so I need to make sure my investments are
safe. The worst thing that could happen would be losing all of my investments
right before I need them.

Speaker D: I'm concerned that investment is always risky. I prefer to hold onto
my money instead of investing it in companies or banks.
