Was DCA or a lump sum better for Amazon?
Over the last 20 years, investing the same $24,000 all at once in Nov 2006 would have grown to $3,072,176, compared with $470,907 by investing $100 a month.

Across 294 rolling 5-year periods of investing $100 a month, the best started in Sep 2013 and returned 55.3% a year; the worst started in Jan 2018 and returned −10.1% a year. 97% of those periods ended with more money than was put in.
How far has Amazon fallen from a peak?
