Stand at the bottom of a canyon and yell, “Buy!” What comes back? “Buy! Buy! Buy!” Pretty soon it feels like the rocks themselves are bullish.
That’s how Echo Trades work. They’re not real signals; they’re just noise bouncing around the walls of the market. But here’s the twist: if enough people believe the echo, it becomes real for a while.
Think back to the meme stock mania of 2021. A Reddit post turned into a thousand tweets, which turned into a million Robinhood trades. AMC and GameStop weren’t magically reinventing themselves as tech giants. They were beneficiaries of echoes — everyone repeating everyone else’s conviction until prices divorced reality.
But echoes don’t last. Like sound waves, they fade. When the canyon goes quiet, latecomers realize they weren’t hearing the truth — just reverberations.

Why does this matter for us?
- Repetition ≠ Truth. If you hear a narrative five times in one day, it feels stronger. But it might just be the same echo bouncing back.
- Echoes create timing windows. Early in the wave, you can profit by surfing the herd. But you need to know when to jump off before the sound fades.
- Not all echoes are bad. Sometimes they help markets discover new themes (renewables, AI, crypto). The key is knowing when an echo crosses into distortion.
And here’s the trick most miss: you can’t stop echoes. They’re a feature of human behavior — mimicry, FOMOphobia, herd instincts. What you can do is build a filter. Ask yourself: is this signal rooted in fundamentals, or is it just reverberation?
Trading echoes blindly is dangerous. But recognizing them early? That’s a chance to arbitrage belief itself.
Next time your feed is flooded with the same “hot take,” remember the canyon. It’s not the rocks talking. It’s your own voice coming back.
