I am about to rollover my 401(k) to an IRA. I know my target asset allocation and it will all be in Vanguard ETFs, but the only question is how to get there. Since this is a sizable chunk to move at one time, I am looking for some advice.
I see three options:
1. Just invest it all immediately when it's available.
Concern: No chance to smooth over an rough spots. I could get lucky and buy on the low side, or unlucky and buy on the high side. On the other hand, since I can't time the market anyway, why not just get it over with?
2. Put in limit buy orders just slightly less than current market, figuring natural volatility will allow the buy to go through during the next dip.
Concern: My "slightly less" is below the dip, the buys never get executed and I miss the increase.
3. Break up the purchase into even amounts over the next several months/weeks and buy on a "dollar cost averaging" basis.
Concern: Slightly more expense in transaction fees (which possibly might be waved), closer monitoring, and loss if market increases (or gain if market decreases).
I recall (I think) in the Bogleheads guide many years ago that option #3 was slightly preferred, but not by much. I was wondering what the latest thought on this issue is.
Thanks
