I just checked my 401k, and I've effectively broken even. I saw that because my employer generously matches my investment dollar for dollar to a point. Effectively they contribute 30% of what I do to my 401k.
Incidentally, with today's market drop I've just hit the 30% lost mark.
I've made the hard choice that I'm going to keep investing even in this time of crisis. I realize I'm just a drop in the pond, but if people like me who've invested so little pull out it won't help the people on the verge of retirement who just saw that dream fade.
I know I'd like to retire before I die, so I'd like to afford the same to those who've come before me. It's not much, perhaps a Pyrrhic gesture, but it's something I can do.
