Not a financial advisor. Personal experience only, not advice — do your own research.
START HERE
Should you dump all your money in at once, or spread it out over time? People treat this like it's the most important decision in investing. It's not — it matters way less than most people think, and overthinking it is usually just fear dressed up as strategy.
Putting your full amount in at once. Statistically, this tends to outperform DCA over long timeframes, simply because markets go up more often than they go down, and time in the market beats waiting for a better entry.
The downside is purely psychological. If you lump sum right before a drop, it feels terrible, even if it doesn't actually change your long-term outcome much.
Spreading your buys out over weeks or months instead of all at once.
Neither approach fixes a bad stock pick. This is purely about when you buy, not what you buy. That decision was already covered in Guide 1.2.
If you're sitting on cash right now afraid to invest it "at the wrong time," ask yourself honestly: is that caution, or is it fear making the decision for you?

The Question Everyone Overthinks
Should you dump all your money in at once, or spread it out over time? People treat this like it's the most important decision in investing. It's not — it matters way less than most people think, and overthinking it is usually just fear dressed up as strategy.
Lump Sum
Putting your full amount in at once. Statistically, this tends to outperform DCA over long timeframes, simply because markets go up more often than they go down, and time in the market beats waiting for a better entry.
The downside is purely psychological. If you lump sum right before a drop, it feels terrible, even if it doesn't actually change your long-term outcome much.
Dollar-Cost Averaging (DCA)
Spreading your buys out over weeks or months instead of all at once.
- Reduces the chance of buying everything right before a big drop
- Makes it easier emotionally to keep buying through dips, since you're not fully committed yet
- Costs you a bit of expected return on average, since you're sitting in cash longer while waiting to deploy
What I Actually Do
For money I already have sitting around, I lean toward DCA over a few weeks or months, mainly for the psychological benefit. For new income coming in regularly, it's automatically DCA anyway, since I'm buying consistently as money comes in.
Neither approach fixes a bad stock pick. This is purely about when you buy, not what you buy. That decision was already covered in Guide 1.2.
SYSTEM CHECK
If you're sitting on cash right now afraid to invest it "at the wrong time," ask yourself honestly: is that caution, or is it fear making the decision for you?
