Nobody knows, that is part of the nature of risk. That is the reason why stocks generally offer greater return than less risky investments.
Suggested action points:
- Fund the IRA now.
- Schedule one-tenth (or whatever fraction you wish) of the total into stocks each month. Automate it, do not decrease it under any circumstance.
- At the end of each month, if the total is "down," move an additional amount along with the one-tenth to "even it up."
- In a year, kick yourself because your timing was wrong.
- Get over it.
That is not what I would do. I would move it all into stocks, now. Up, down, whatever. (And I would be likely "wrong" in some way - Oh well, I'll kick myself and move on.)
