Does the Donchian Breakout strategy beat buy & hold on AMD? (AMD · backtested honestly)
The 'turtle' channel rule: it tracks the highest high and lowest low of a recent window (both excluding the current bar) and trades a break beyond them.
Over this period, Donchian Breakout on AMD returned +238.6%, while simply buying and holding returned +381.1% — it lagged buy & hold by 143 points, with a worst drawdown of -40.6%. It traded 18 times and sat in cash about 60% of the time. It's a mechanism you test.
It lagged buy & hold over this window — that's a result, and a backtest you can kill for free just did its job. Re-tuning this same idea until it looks better only adds another shot at looking good by luck, so the honest next move is a fresh one: test a different strategy on AMD, or build your own — free. Most ideas die cheaply right here, and that's exactly how the rare one that holds up gets found.
Or stop here — walking away from an idea that didn't beat simply holding is a result, not a failure.

Shown at the modeled fills — entries at the next open; a stop at its level, or at that day's open if the day opened past it; a target at its level; costs on. A single trade is never a signal and says nothing about the next one — not the best or worst, a middling winner and a middling loser among the completed trades.
18 trades total — 10 winners, 8 losers (56% won). Below is one of each, not a scoreboard.
- Entry. A long entry fired; filled at the next open on 2022-05-18 at $100.00 — never the signal bar's own close.
- Held. 18 daily bars.
- Exit. Exited on 2022-06-14 at $87.41 (the exit rule fired (filled at the next open)).
- Result. -12.69% after costs.
The worst single trade in this whole test reached -20.56%.
- Entry. A long entry fired; filled at the next open on 2023-05-11 at $98.16 — never the signal bar's own close.
- Held. 28 daily bars.
- Exit. Exited on 2023-06-22 at $112.24 (the exit rule fired (filled at the next open)).
- Result. +14.24% after costs.
Trading costs + slippage (0.10%) are already deducted from every figure above. One trade is never the edge — it's the whole distribution (the win rate, the losers, the reality-check) that matters; this just makes the mechanics concrete. It describes the past; it is not a prediction.

- • The strategy line is Donchian Breakout on AMD; the dashed line is simply buying and holding AMD. Beating the dashed line is the whole point — many strategies don't.
- • Max drawdown is the worst peak-to-trough fall you'd have sat through. A higher return with a much deeper drawdown is not obviously better.
- • Every fill assumes next-open execution with costs & slippage on — no acting on prices you couldn't have known.
- • A small number of trades means a small sample. Treat a great-looking result on a handful of trades with suspicion.
This is a hypothetical backtest of a well-known mechanism on past data. It is not advice, not a prediction, and not a claim that the strategy works. We hold no funds and place no orders. The value here is the ability to test an idea honestly — see where it would have helped, and where it would have hurt — before you ever risk real money on your own broker.
