Does the MACD strategy beat buy & hold on Dow Jones ETF (DIA)? (DIA · backtested honestly)
The MACD line is the difference between a fast and a slow EMA; the signal line is an EMA of that. Go long when MACD is above its signal line, flat when below. A momentum/trend rule that reacts a little faster than a raw MA crossover.
Over this period, MACD on Dow Jones ETF (DIA) returned +10.4%, while simply buying and holding returned +65.5% — it lagged buy & hold by 55.0 points, with a worst drawdown of -15.4%. It traded 53 times and sat in cash about 53% of the time. It's a mechanism you test — not a recommendation.
That's the past — settled, free, and the weakest proof there is. The honest next move isn't to trust it — it's to try to break it: does the edge hold across nearby settings and time, or was it luck? Most strategies that look good here don't survive that, and most should stop there. The few that do still haven't met a future nobody has lived yet. Forward-test MACD on Dow Jones ETF (DIA) on paper — zero hindsight, losses and all — and get a mechanical alert the day it signals (you trade on your own broker). A hindsight-free track record can only be built by time passing, so the only way to have proof in three months is to start today.
Or stop here — a backtest you can kill for free has already done its job.

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.
