I'm sure you'll do well with your purchases made over the course of three whole days Spencer, because you always do well. However, I'm not so sure that when the great guru Peter Lynch was referencing "dollar cost averaging" he had a three day period in mind. Maybe he did, I dunno, but I've always understood "Dollar Cost Averaging" as investing at regular set intervals over the course of a period of months, quarters, years...not three days. Establishing your position in three days seems more like timing than averaging in over time.
