‘Buy the dip’ has become one of those phrases repeated so often it stops sounding like a decision and starts sounding like a fact of markets. It isn't. A dip is just a price that has fallen — it says nothing on its own about whether it will keep falling.
The phrase works retroactively. After a stock recovers, every dip along the way looks like a gift. Before it recovers — while it's still falling — the exact same price action looks like exactly what it might be: the start of a much deeper decline.
What separates a real dip-buy from a hopeful one
- A real dip-buy has a specific level being defended — a prior support zone, not an arbitrary percentage down.
- It has a predefined invalidation point where you're proven wrong and you exit, decided before the entry.
- It's sized so that being wrong costs you a known, small amount — not sized on how confident the idea feels.
- It's backed by a reason the fall might stop — not just 'it's cheaper now than it was'.
None of this guarantees the trade works. It just means that when you're wrong, you'll know quickly and cheaply — instead of finding out three months later, much poorer, that you were buying a falling knife the whole way down.
