Every investor asks the same question at some point: should I wait for a better moment to start? Here is why time in the market tends to matter more than timing the market, and how to get moving even with a small amount.
“When should I invest?” and “Should I invest at all?” feel like the same question, but they lead to very different behaviours. The first one invites endless waiting: waiting for a dip, waiting for more savings, waiting for “clarity” on the economy. The second one is simpler and, for most long-term investors, more useful: once you know you want to build wealth over years or decades, the exact week you begin matters far less than the fact that you began.
This is not a claim that timing never matters. It is a reminder that trying to nail the perfect entry point is a different skill than investing itself, and it is one that even professional fund managers struggle to do consistently. For a DIY investor building a long-term portfolio, chasing the perfect moment often becomes an excuse to do nothing.
“Timing the market” means trying to predict short-term moves: buying right before a rally and selling right before a drop. It sounds appealing in theory, but it requires being right twice — once on the way in, once on the way out — repeatedly, over a lifetime of decisions. Very few people, professional or amateur, manage this consistently enough for it to be a reliable strategy.
“Time in the market” is a different approach entirely. Instead of trying to predict the next move, you accept that markets go up and down unpredictably in the short run, but that staying invested lets your money participate in the underlying growth of businesses and economies over long stretches of time. The strategy is not about being clever in any given month. It is about being present, consistently, for enough months and years that short-term noise matters less.
The practical implication for a DIY investor is simple: a sound plan you actually follow tends to beat a brilliant plan you keep postponing.
Compounding is the process by which your returns start generating their own returns. In plain terms, growth builds on top of previous growth, not just on your original contribution. This is why the number of years your money stays invested matters as much as the amount you invest, if not more.
Qualitatively, this means a dollar invested earlier has more time to go through this snowball effect than a dollar invested later, even if the later dollar is larger. It also means that missed early years are hard to make up for later, since there is no way to “borrow” extra time. This is not a prediction about what returns will be — nobody can know that in advance — it is simply a description of how compounding works mechanically once money is invested and given time.
The takeaway is not “invest a lump sum you don't have.” It is that the earliest reasonable moment to start, even modestly, tends to matter more than most people assume, precisely because time is the one input compounding needs that cannot be recovered after the fact.
Waiting for a market dip before investing sounds prudent. In practice, it runs into a few real problems.
None of this means dips don't matter or that valuation is irrelevant. It means that using “waiting for a dip” as a substitute for having any plan at all tends to cost more, in lost time, than it saves.
Rather than asking “is now a good time to invest,” a more productive question is “what is my plan, and does today fit into it?” A plan might include how much you can contribute regularly, which accounts you'll use (like a TFSA or RRSP), how your portfolio is diversified, and how long you intend to stay invested. Once that plan exists, the specific day you start matters far less than starting somewhere and sticking to the plan through both up and down periods.
This is also where consistency tends to help more than precision. Contributing regularly, in amounts that fit your budget, removes the pressure of picking a single “right” moment. It replaces one big decision with many small, repeatable ones, which is generally easier to sustain over years.
You do not need a large lump sum to begin. A few practical starting points:
The cost of waiting to invest isn't a single number you can point to — it's the accumulation of missed time, delayed habits, and decisions postponed in search of certainty that rarely arrives. Markets will always offer a reason to wait a little longer. The investors who benefit most from compounding are typically not the ones who guessed the perfect entry point, but the ones who started early, kept contributing, and let time do the rest.

There's no way to know in advance whether any specific day is a good or bad entry point — that's the nature of short-term market movements. What matters more for a long-term investor is having a plan you can stick with, rather than trying to predict the next few weeks or months.
Starting small is still starting. The benefit of compounding comes from time in the market, not necessarily from a large initial amount. Many investors begin with modest, regular contributions and build from there.
That depends on your personal situation, such as debt, emergency savings, and goals. But waiting indefinitely for a larger amount means giving up time that compounding can't get back later, so it's worth weighing that trade-off deliberately rather than by default.
Having a clear plan, using regular contributions, and keeping a consolidated view of your portfolio can all help reduce the urge to react to short-term news. Revisiting your plan periodically, rather than constantly, also helps keep decisions grounded in your long-term goals.
