Well I guess if you think we are in volatile market then there might be some reason to DCA vs Lump sump.
But in general from most analysis, time in market beats DCA, but from psychological point, it might be easier to DCA as with LS you get this single big payment where next day it might turn “big” red, so you think you missing out la la noise short term.
But anyway there are plenty of good articles, even tho most cover LS vs DCA start of investment, if you had XYZ cash stashed. Salary investment DCA vs LS has even minor effect, but anyway for those that like to read.
