Amgen Inc. (AMGN): DCA vs Lump Sum
Which investment strategy performed better historically?
What is Dollar-Cost Averaging (DCA) vs Lump Sum Investing?
Dollar-Cost Averaging (DCA)
DCA means investing a fixed amount at regular intervals (e.g., $500/month), regardless of the stock price.
- • Buy more shares when prices are low
- • Buy fewer shares when prices are high
- • Reduces impact of market timing
- • Matches how most people invest (from paychecks)
Lump Sum Investing
Lump sum means investing your entire amount at once, getting all your money working in the market immediately.
- • Maximizes time in the market
- • Historically wins ~67% of the time
- • Better in consistently rising markets
- • Best for windfalls (inheritance, bonus)
Which is better? Academic research (including a famous Vanguard study) shows lump sum investing outperforms DCA about two-thirds of the time because markets tend to rise over time. However, DCA's real advantage is psychological—it's easier to invest $500/month than to put $60,000 in at once, and many investors would otherwise keep money on the sidelines.
For AMGN specifically: Over the past 5 years, investing $500/month (totaling $30,000) would have grown to $45,708 with DCA, versus $52,074 with lump sum. Lump sum won by $6,366, reflecting AMGN's strong upward trend.
