Dollar-cost averaging works — but should you invest weekly, monthly, or daily?** In this video, we break down what years of S&P 500 data (1990–2020) actually show about investing frequency, and why the difference is smaller than most finance influencers claim.
Most people assume investing weekly beats monthly, but the real story is more nuanced. We dig into backtested data, explain why the statistical gap between weekly and monthly dollar-cost averaging is often under 0.5% annualized, and show you exactly when frequency actually matters — and when it's just noise.
By the end of this video, you'll understand:
- Why monthly investing is the practical default for most salaried investors
- When weekly investing gives you a real edge (hint: large contributions + volatile markets)
- Why daily investing rarely justifies the extra transaction costs
- How to adjust your investing schedule if you have irregular income
- What changes when you're investing in high-volatility assets like crypto or small-cap stocks
We also cover real-world examples from the 2020 COVID crash and the 2022 rate-hike selloff to show how timing risk plays out in practice. Whether you're automating contributions through Fidelity, Vanguard, or another broker, this breakdown will help you build a smarter, more consistent investing habit — without overthinking every purchase.
If you've ever wondered whether your investing schedule is actually costing you money, this video will settle the question for good.
