What should I do with my 401(k)?

Let the autopilot of your 401(k) work for you. The accounts invest steadily in good periods and bad - and that has paid off for most people over time. That said, this is a good time to examine whether your asset allocation is in line with your long-term strategy. For example, consider trimming your exposure to small caps, which have been strong and are due for a correction. "So many people have this habit of investing their 401(k) and leaving it there like an old box in the attic, and it really needs revisiting," says Sarah Ketterer, chief executive of Causeway Capital.
