According to Vanguard research, which investing approach produced higher returns in approximately 2 out of 3 historical periods?

Vanguard's study of 68 years of US market data found lump sum investing outperformed 12-month DCA in ~67% of rolling periods, with an average 2.3% higher return in year 1. Markets go up more often than down, so time in market typically beats timing the market.

Which strategy historically produces higher returns: lump sum or DCA?

Lump sum wins approximately 2/3 of the time with ~2.3% higher first-year return (Vanguard study). Because markets trend upward, being invested sooner usually beats spreading investments over time.

When does DCA outperform lump sum?

When markets fall significantly right after the investment date. DCA also captures those lower prices. But this only happens 1/3 of the time historically.

What is the "real enemy" of both lump sum and DCA investors?

Staying in cash and waiting for the "perfect" entry point. Opportunity cost of missed market gains almost always exceeds the benefit of timing the entry.
