Calculations for Axcelis Technologies

Expectancy is the percentage profit or loss you would expect to make on the next purchase of this stock with an entry point at the specified signal and profit target as set above. Given a large enough sample size, a positive expectancy indicates the trading strategy is likely to be profitable.

Expectancy calculation for 31 signal(s) occurring before 21 July 2024 for a 7.5% profit target: (96.77% * 8.99%) + (0% * 0%) - (3.23% * 4.59%) = 8.55%.
Wins: 30 Breakevens: 0 Losses: 1

To even out CAGR calculations, large individual returns from particularly quick trades have been capped at 300%.

The Sharpe Ratio calculation assumes a risk free return rate of 2% per calendar year. Ideally the ratio should be a positive number. A higher positive number indicates the strategy has a more attractive risk adjusted rate of return for this particular buy signal and stock over the chart's timeframe.
