thanks and happy new year
Almost all academic studies have shown that a lump sum works best. This makes sense, since markets rise over time and investing early gets more compounding. In our experience with investors, however, we have found that many are just not comfortable doing this and the discomfort leads to the wrong decisions at the wrong time. Instead, a monthly (12 to 18 month) fixed contribution allows investors to (a) understand that the market should be a long term investment and (b) realize that, as buyers, volatility is their friend. A systematic approach we have found makes investors calmer, and a calmer investor is more likely to invest for the long term, and get the benefits of compounding.
