The answer to this question depends on individual circumstances and risk tolerance. Research has shown that lump sum investing tends to outperform dollar cost average investing in the long run, but dollar cost averaging can provide a more disciplined approach for those who are uncomfortable with market volatility. It is important to evaluate your own goals and comfort level with risk before deciding which approach (lump sum or dollar cost averaging) is best for you. Consulting with a financial advisor can also help you make an informed decision.
