DCA for those with low risk appetite and limited investment knowledge

Lump sum investing works only if you have a sum of "disposable" capital that you don't mind putting aside regardless the market movement and fully know what you are investing on. For most investors, DCA might be the safer option given that you are less affected by the market movement and the risks are more distributed over an extended period of investment. DCA is also more manageable in terms of capital requirement since you only need to set aside a sum of funds at regular intervals for the funds to do its own magic (think of it as a regular savings account). Overall, would still opt for DCA as the preferred investment method.
