With the markets doing horribly, I will likely see an immediate loss on my initial $3000 investment. Would I be better to keep adding to my $3000 in savings (making about 3% interest) and then open the Roth IRA later this year (or whenever the markets calm down)? Or should I just open the account now with my $3000 initial investment and dollar-cost average into the account over the next few months to max it out, and not look back?What you are doing is not DCA (dollar-cost averaging) but Peridodic Investment. Lots of people (even financial advisors) confuse the two. DCA isn't good, PI is very good.The best time to invest is when the market is down huge. That's the "buy low" of the rule---buy low, sell high.With the markets doing horribly, I will likely see an immediate loss on my initial $3000 investment.So????? Are you investing for next week or for the next 30 years?I personally don't like the target funds. It's a gimmick to have a part stocks and part bonds allocation. At your age you should be in all stocks and no bonds.
