Does the MACD strategy beat buy & hold on Micron Technology? (MU · backtested honestly)
A momentum gauge built from the gap between a fast and a slow EMA, with a signal line that is an EMA of that gap.
Over this period, MACD on Micron Technology returned +167.1%, while simply buying and holding returned +1458.1% — it lagged buy & hold by 1291 points, with a worst drawdown of -46.3%. It traded 51 times and sat in cash about 50% of the time. It's a mechanism you test — not a recommendation.
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 Micron Technology, 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, protective stops and targets at their 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.
51 trades total — 28 winners, 23 losers (55% won). Below is one of each, not a scoreboard. One position is still open at the window end — its result is unrealized and is counted in the totals above at its current mark, not shown as a card below.
- Entry. A long entry fired; filled at the next open on 2025-08-11 at $124.97 — never the signal bar's own close.
- Held. 10 daily bars.
- Exit. Exited on 2025-08-25 at $117.68 (the exit rule fired (filled at the next open)).
- Result. -5.93% after costs.
The worst single trade in this whole test reached -17.88%.

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.

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. I 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.
