Investopedia explains 'Dollar-Cost Averaging - DCA'
Eventually, the average cost per share of the security will become smaller and smaller. Dollar-cost averaging lessens the risk of investing a large amount in a single investment at the wrong time.
For example, you decide to purchase $100 worth of XYZ each month for three months. In January, XYZ is worth $33, so you buy three shares. In February, XYZ is worth $25, so you buy four additional shares. Finally, in March, XYZ is worth $20, so you buy five shares. In total, you purchased 12 shares for an average price of approximately $25 each.
In the United Kingdom, it is known as "pound-cost averaging."
