In a bull market you get things for cheap, with the expectation that the bull market will end long enough before your retirement that those assets will increase in value. You basically bought those assets at a discount. Bonus!
Closer to retirement, you wouldn't want to take on that much risk, so you'd move (over time, as you get closer to retirement) to more stable investments. Target-date mutual funds[0] do this automatically.
