As usual, Ben has some insightful comments to make. Let me add one more: Dollar cost averaging protects the buyer when the buyer has made a fundamental mistake to purchase in the first instance. In that situation, purchasing can be stopped and losses prevented.

Using dollar cost averaging is a statement/admission of uncertainty. Here's my view: if an investor is uncertain, don't buy the stock.
