so should i stop contributing to my 401k or not?
No.
We are close to the bottom, but the bottom is still illusive. Some day, the markets will return. If I recall, it's about 6800, rebounded a bit. Consider if you invested $1,000 into the market. If they follow the market and go back to say Dow of 14000, these stocks are now worth over $2,000. Buy low. If you wait for the recovery, you wont make the profit. Now of course, this is for long term investing. Not short term.
Since I changed jobs, my old 401k funds have lost about 40% or more and my new investments have been in Security Investments, which have made just under 1%. I'm simply letting the stocks I already have ride it out because I know they will recover. At some point soon, I will roll all those security investments into stocks, and make all my biweekly contributions go to stocks as well. I just haven't decided when is the right time yet. I'm expecting to see below a 6000 on the Dow, but I could be wrong. I actually expect it to drop as low as 5000, but I will place it in at 6000 if it goes that low, so I don't miss a good buying point. If it breaks 7000 however, maybe I'm wrong, and I'll consider putting it in then. It's just hard to say. The market responds fast to democrat policies in the negative, and slow to positive signs. I really think it will still go lower with this congress and president.
