Over how much time should I dollar-cost-average my bonus from cash into mutual funds?
I'm staring at this chart and asking myself, How long a period is enough to have an average I'd be happy with regardless of the direction the market goes?  3 years? 4 years? Clearly, a lump sum investment risks a 2000 buy at 1500. Not good. Honestly, I love the question, and find it interesting, but there's likely no exact answer, just some back and forth analysis. You're investing about $40K/yr anyway. I'd suggest a 4 year timeframe is a good time to invest the new money as well. Other folk want to offer opinions? Edit - with the OP's additional info, he expects these bonuses to continue, my updated advice is to DCA quarterly if going into assets with a transaction fee or monthly if into a no-fee fund, over just a one year period.
