Many of us delay investing (or fail to start at all) because we’re either intimidated by choosing investments or we’re afraid of the risk. An automatic investment plan can help. One of the techniques I outline here requires zero investing knowledge to
get started—it’s as easy as opening a bank account. And, when you put your investments on autopilot, you take your emotions out of investing, which can temper your fear—or at least limit fear’s ability to cost you money. Let’s look at how an automatic investment plan does this.
The technique of buying a fixed amount of an investment at regular intervals is known as dollar cost averaging (as opposed to investing a big chunk of money at irregular times).
If you were to buy $1,000 of a mutual fund when it’s per-share price is $100, you would own 10 shares.
If, however, you invest $100 a month for ten months and the fund’s price varies from $80 to $120, you may end up slightly more or less than 10 shares depending on the stock prices. As the market climbs, the notion is you will end up buying more shares at a lower price than if you invested in a lump sum. Advocates of dollar cost averaging say this reduces risk, but critics disagree. The market goes up in the long run, so you want to get money in as soon as possible.
If you have a lump sum sitting around that you want to invest, then do it. Get it into the market and don’t worry about spreading it around and definitely don’t try to time the market or wait for the right time.
