Over how much time should I dollar-cost-average my bonus from cash into mutual funds?
Canadian Couch Potato has an article which is somewhat related. Ask the Spud: Can You Time the Markets? The argument roughly boils down to the following: That said, I didn't follow the advice. I inherited a sum of money, more than I had dealt with before, and I did not feel I was emotionally capable of immediately dumping it into my portfolio (Canadian stocks, US stocks, world stocks, Canadian bonds, all passive indexed mutual funds), and so I decided to add the money into my portfolio over the course of a year, twice a month. The money that I had not yet invested, I put into a money market account. That worked for me because I was purchasing mutual funds with no transaction costs. If you are buying ETFs, this strategy makes less sense. In hindsight, this was not financially prudent; I'd have been financially better off to buy all the mutual funds right at the beginning. But I was satisfied with the tradeoff, knowing that I did not have hindsight and I would have been emotionally hurt had the stock market crashed. There must be research that would prove, based on past performance, the statistically optimal time frame for dollar-cost averaging. However, I strongly suppose that the time frame is rather small, and so I would advise that you either invest the money immediately, or dollar-cost average your investment over the course of the year. This answer is not an ideal answer to your question because it is lacking such a citation.
