Dollar-Cost Averaging: Timing the Market is Impossible

The question haunts every investor: "Is now the right time to buy?" The market is at an all-time high—should I wait for a crash? The market is crashing—should I wait for the bottom?

The answer, almost always, is "Yes, if you plan to keep buying." The strategy that removes this paralysis is called Dollar-Cost Averaging (DCA).

The Trap of Market Timing

Trying to "buy the dip" sounds smart. But in reality, it's nearly impossible to predict the bottom.

Investors who sit on cash waiting for a crash often miss out on the biggest market rallies. By the time they feel "safe" to enter, the market has already recovered. Peter Lynch famously said, "Far more money has been lost by investors preparing for corrections, or trying to anticipate corrections, than has been lost in corrections themselves."

What is Dollar-Cost Averaging?

DCA is the strategy of investing a fixed amount of money at regular intervals (e.g., $500 every month), regardless of the share price.

Psychological Benefits

The biggest advantage of DCA isn't mathematical—it's psychological. It removes the emotion from investing.

When the market crashes, a normal investor panics. A DCA investor celebrates, because their monthly contribution is buying more shares "on sale." It turns a negative event into a positive opportunity.

DCA vs. Lump Sum

If you have a large pile of cash today (e.g., an inheritance), studies show that investing it all at once (Lump Sum) mathematically beats DCA about 66% of the time, because markets tend to go up.

However, DCA is the regret minimization strategy. If you invest a lump sum and the market crashes tomorrow, you will feel terrible. If you DCA over 12 months, you won't care. For most people, the psychological safety of DCA is worth the slight mathematical cost.
