00:00Monthly investing is the more practical default for most investors,
00:04though the return difference between weekly and monthly dollar cost averaging is statistically
00:08negligible. A widely cited backtest by Northwestern Mutual and several independent analyses of S&P
00:15500 data, 1990-2020, found that weekly versus monthly DCA produced return differences under
00:230.5% annualized over 10-plus-year periods, with weekly showing a marginal edge in volatile markets
00:30due to more frequent entry points averaging out short-term dips. The real distinction is
00:35operational, not statistical. 1. Monthly investing, lower transaction friction,
00:41aligns with salary cycles, easier to automate through brokers like Fidelity or Vanguard with
00:47zero added fee tiers, best for salaried investors with predictable income.
00:512. Weekly investing, smooths volatility slightly better during high volatility periods,
00:57e.g. 2020 COVID crash, 2022 rate hike sell-off, but only matters meaningfully if you're investing
01:04large sums, greater than $5,000 per month, where timing risk is non-trivial.
01:103. Daily investing, theoretically optimal for risk smoothing but adds negligible benefit,
01:16typically. The answer changes with context. If you're investing small amounts,
01:20$200 per period monthly reduces overhead and psychological fatigue. If you receive a regular
01:26income, freelancers, commission-based, align contributions to cash inflow rather than a fixed
01:32calendar schedule. If you're in a high-volatility asset class, crypto, small-cap stocks, weekly or
01:39bi-weekly reduces the risk of a single bad-timing lump payment. I don't have confirmed post-2023
01:46data isolating weekly versus monthly performance specifically, so treat the negligible difference,
01:52claim, as reasonably reliable through 2020 but not verified for the most recent market cycle.
01:58Practical takeaway, default to monthly DCA aligned with your paycheck unless you're deploying large
02:04capital into volatile assets, in which case split contributions weekly to reduce single-point
02:10timing risk. Finally, remember that everything we discussed today is for educational purposes only
02:16and does not constitute financial advice. Good luck to everyone and see you in the next video.
