Larry Williams volatility breakout on QQQ: did it beat simply holding?

The rule target = open + k × yesterday's range, applied to QQQ since 2000 with different k, a moving-average filter and trading costs.

Summary

Applying a k 0.5 volatility breakout to QQQ from January 2000 turned $10,000 into $63, an annual return of −17.3%. Buy and hold ended at $91,226, or 8.6% a year.

The rule traded 2,800 times, and the 0.15% cost on every buy and sell changed the result a lot. With a 0.05% cost the same rule returned 2.0% a year, and with no cost 13.2%.

All four variants of k and filter lost money; k 0.7 lost the least at −11.4% a year.

Common questions

Is the next-day sell at the open the original rule?

Larry Williams described exiting at the next open or on a stop. Versions that sell at the same day's close also circulate. This calculation uses the next open.

How often did a trade win?

Over the full period, 57% of trades sold at the next open above the buy price before costs.

How did it do on SPY?

Over the same full period, SPY returned −26.0% a year at a 0.15% cost and 1.7% at no cost, against 8.2% for buy and hold. At a 0.15% cost that was below QQQ (−17.3%).

Are dividends included?

Yes. This volatility breakout calculation reinvests each dividend at the price on its ex-dividend date. Taxes on dividends are not deducted.

Would the result be the same when investing in a currency other than dollars?

No. This volatility breakout calculation is in US dollars. Exchange rate changes and the fee and tax differences of locally listed ETFs are not included.
