re: What would you do in regards to 401k investment strategy based on my situation?

Other than knowing that you’ve been with your company for 25 years, we don’t know anything else about your situation (financially or otherwise). But no matter what, having all of your retirement funds in one stock (especially the company you work for) is a tremendous gamble. Just because it’s worked out (so far) doesn’t make it wise… some gambles pay off. Let’s say something unexpected happens and your company hits a rough patch. The company stock takes a tumble and at the same time, you lose your job. Doesn’t matter how remote the possibility is, it’s still a possibility. I’d diversify and mitigate that risk.

Good luck.
