Just Keep Buying is a simple accumulation framework for long-horizon investors. Choose diversified, inexpensive assets, contribute on a recurring schedule, and continue through both rising and falling markets. Its mechanism uses consistent saving and decades of compounding while reducing the behavioral damage caused by forecasting, frequent account checks, and loss aversion. The investor does not need to identify each market top or bottom; regular purchases acquire more units when prices are low and maintain participation when recoveries begin. Periodic reviews keep allocation and cash needs aligned, but daily market movement does not dictate action. The framework is especially powerful for younger investors because future contributions and a long time horizon make temporary bear markets less consequential.

How to run it
- 1
Protect near-term cash
Separate emergency funds and money needed in the next few years from long-term investments. Only commit capital that can remain invested through a major decline.
Pro tip Automate emergency savings before increasing investment contributions.
Watch out A forced sale during a bear market can defeat the strategy.
- 2
Choose broad, low-cost exposure
Select a diversified fund or portfolio with low ongoing fees. Avoid making the plan dependent on one company, theme, or speculative asset.
Pro tip Prefer products whose purpose and costs you can explain simply.
Watch out Regularly buying a failing concentrated asset is not diversification.
- 3
Automate purchases
Schedule contributions to coincide with income so investing happens without repeated decisions. Treat the contribution as a recurring obligation to your future self.
Pro tip Use automatic payroll or bank transfers where available.
Watch out Waiting for the perfect entry point can leave cash uninvested indefinitely.
- 4
Continue through declines
Maintain purchases during bear markets when employment, cash reserves, and the long-term plan remain intact. View lower prices as part of the accumulation process rather than proof that the method failed.
Pro tip Write the bear-market rule before the next decline.
Watch out Do not increase risk if your job or emergency reserves are threatened.
- 5
Check less often
Reduce account monitoring to limit myopic loss aversion and impulsive trading. Review on a predetermined monthly, quarterly, or annual schedule.
Pro tip Remove trading-app notifications from your phone.
Watch out Frequent checking can turn temporary volatility into unnecessary action.
- 6
Raise the contribution rate
Direct part of raises, bonuses, or reduced expenses into the recurring purchase. Let the system scale with income rather than relying only on investment returns.
Pro tip Increase the automated percentage before lifestyle spending expands.
Watch out Do not sacrifice essential insurance or high-interest debt repayment.
In the wild
A graduate builds an emergency reserve, selects a diversified low-cost index fund, and automates a contribution after every payday. When markets fall, the purchases continue unchanged and acquire more shares at lower prices. The investor checks quarterly rather than reacting daily.
→ The investor maintains participation, avoids market-timing paralysis, and builds a repeatable compounding habit.
After living through several bear markets, Jakab says he spent too much time handicapping and worrying about market conditions. He concludes that consistently buying and checking less would have been the better approach over decades.
→ The experience supports a simpler accumulation process over repeated forecasting.
Common mistakes
Waiting for certainty
Markets rarely provide a moment that feels both safe and attractively priced, so waiting can become permanent inaction.
Checking the account constantly
Frequent exposure to losses increases anxiety and the likelihood of selling or trading unnecessarily.
Applying the rule to any asset
The method assumes durable, diversified exposure; repeatedly buying a structurally impaired company can compound losses instead of wealth.
Is it for you?
Best for
It is best for people with regular income, diversified investments, and a horizon measured in decades.
Not ideal for
It is not ideal for money needed soon or for concentrated securities whose fundamentals may permanently deteriorate.
