re: When do you start becoming conservative with 529 accounts?

I started with the age based strategy, where it automatically pulls back and becomes more conservative after certain age milestones, starting with their 9th birthday. I have a nice chunk so far, so I reduced that strategy and added a little more risk. My thinking is the conservative strategy will get me through 3 years of college, adding to a recovery timeline when I actually need the remaining funds.

You should pull back on at least a portion of the investment.
