Today, I would like to touch on the an investment strategy, Dollar-Cost Averaging, or people used to name it 'DCA'. You might have already knew, dollar-cost averaging in fact is a popular investment strategy where you invest a fixed dollar amount at a pre-determined intervals. Simply say, when the markets are up, you buy fewer shares per dollar invested due to the higher cost per share. When the markets are down, you buy a greater number of shares per dollar invested. This strategy allows us to get an average cost per share over time, meaning you don't have to invest the time and effort to monitor market movements and strategically time your investments.
This is the DCA we talking about today.
According to Timothy Middleton, a writter of moneycentral articles, when the market is studied over long periods, dollar-cost averaging almost always produces lower returns than investing lump sums in diversified portfolios, and almost never reduces risk meaningfully. Calculation below are the evident he found:

Assumes total investment of $3,000. Total returns include reinvested dividends as follows: 8 cents on 3/26; 9 cents on 6/25; 9 cents on 9/24 and 18.5 cents on 12/23.

DCA always illustrated in capture lower prices along the way but finish nicely ahead.
Even Phil Town, the best selling author of Rule #1 - The Simple Strategy for Successful Investing in Only 15 Minutes a Week, also complaint about the costly myth of dollar-cost averaging. He emphasized on why we need to buy when there is high cost per share. Will it be better we only buy when the cost is low?
In my opinion, be it DCA, random or lump sum strategy, we only can maximize our investment when we aim at the right time, come with a goal or plan. Since everyone saying we cannot predict the market and most of the time it will goes up and down, it doesn't mean we cannot do anything with it but to stick with DCA strategy. Lump sum investment results in better returns most of the time, because you have the money in the market longer. This is based on the idea that the longer you have your money in the market, the better your returns are over the long run, as shown in the table above.
You should buy and read this book if you haven't.
I think I've bull shit too much, as I believe you must be better than me on this already. In summary, as what old man said, the bottom line is, whatever strategy you apply, investing is better than not investing. Cheers. :)
