Looked in on my Fidelity account which is my company matched 401k and Employee Stock Purchase Program stock as well. Both are doing well especially the ESPP. That one alone is up 54% since I started a year and a half ago. Sure, that includes the gains from the discounted price I bought the stock at but it's still a gain. The 401k is difficult for me to know percentages since I get a good company match. It does show what I put in and what the company puts in though and those numbers make me happy
ESPP's are worth it!
