Use dollar cost averaging to take advantage of changing share prices

Investing in the stock market can be an excellent way to grow your wealth over time, but it can be intimidating to invest a lump sum of money all at once. That's where dollar-cost averaging comes in. Dollar-cost averaging is an investment strategy where you invest a fixed amount of money at regular intervals over an extended period. In this blog post, we will discuss what dollar-cost averaging is and how it can help you when purchasing shares.

What is Dollar-Cost Averaging?

Dollar-cost averaging is an investment strategy where you invest a fixed amount of money at regular intervals over a specified period. For example, if you decide to invest $100 in a stock every month for a year, you are using a dollar-cost averaging strategy.

How does it Work?

Dollar-cost averaging works by buying shares of a particular stock or investment at different prices over time. When you invest a fixed amount of money at regular intervals, you buy more shares when prices are low and fewer shares when prices are high. Over time, this can help you get a better average price for your shares, which can help you achieve better returns.

Let's say you want to invest $1,200 in a particular stock. Instead of investing the entire amount at once, you decide to use a dollar-cost averaging strategy and invest $100 every month for a year. If the stock's price is $10 per share in the first month, you will be able to buy ten shares with your $100 investment. If the price goes up to $15 per share in the second month, you will only be able to buy six shares with your $100 investment. If the price drops to $5 per share in the third month, you will be able to buy twenty shares with your $100 investment etc.

Over the year, you would have invested a total of $1,200, and you would have bought shares at varying prices. This could see the number of shares you own and your average share price paid be higher or lower than what may have been the case if you spent $1,200 all at once.

The Advantages of Dollar-Cost Averaging

  1. Reduces Risk: By investing a fixed amount at regular intervals, you reduce the risk of investing a lump sum of money at the wrong time. When you invest a lump sum of money, you run the risk of investing when prices are high, which can lead to lower returns.

  2. Automatic Investing: Dollar-cost averaging allows you to invest automatically without having to time the market. It takes the emotion out of investing, and you can be confident that you are investing regularly.

  3. Lowers Average Price: Dollar-cost averaging allows you to buy more shares when prices are low and fewer shares when prices are high. Over time, this can help you achieve a better average price for your shares, which can lead to better returns.

The Disadvantages of Dollar-Cost Averaging

  1. You Might Miss Out: If the market experiences a significant increase in price, dollar-cost averaging might cause you to miss out on some gains. However, it is challenging to time the market, and dollar-cost averaging can help you achieve better returns over the long term.

  2. It Might Not be Suitable for all Investments: Dollar-cost averaging is an excellent strategy for long-term investments. However, it might not be suitable for short-term investments or investments with high volatility.

Final Word

Dollar-cost averaging is an excellent investment strategy that allows you to invest a fixed amount of money at regular intervals over a specified period. It can help you reduce risk, invest automatically, and achieve a better average price. If you utilise Dividend Reinvestment as your dollar-cost averaging method you can purchase more shares without having to pay out any cash to do so.
