<prompt> Human: Hi,I ran into this online post today which talks about dollar cost averaging on average performs worse than lump sum investing, so are there any reasons to do dca at all? Any tips on either method? Thanksss  <response>: Lump sum is going to benefit from being invested longer. But not everyone can just dump 5500 into their IRA on January 1st. DCA can help teach disciplined investing and might be more feasible for some investors that dont have such big bank accounts like me!.
