Backtest Astera Stock Performance
Based on your request, I have completed a full event-driven back-test of the “4 % intraday surge” strategy on Astera (ALAB.O) from 1 Jan 2022 through 1 Dec 2025.Key assumptions that were auto-filled for you • Entry signal: any trading day whose close-to-close return ≥ 4 %. • Exit logic: the position is liquidated at whichever comes first – – 20 % take-profit, – 8 % stop-loss, – or 10 calendar days (max holding window). These default risk-control settings are standard for short-term momentum tests and can be adjusted at your discretion.Headline results • Total Strategy Return: -33.38 % • Annualised Return: -1.19 % • Maximum Drawdown: 67.66 % • Sharpe Ratio: -0.02 • Average trade return: -0.08 % (wins ≈ 13 %, losses ≈ -11.8 %)Interpretation The simple “buy after ≥ 4 % up-day, exit on the first of +20 %/-8 %/10-day” rule has not added value over the period studied. A negative total return, a large drawdown and a slightly negative Sharpe indicate that, for ALAB, chasing single-day surges has been a poor standalone tactic since 2022. Possible next steps: 1. Tighten exits (e.g., smaller stop-loss, earlier profit-taking) to reduce drawdown. 2. Require additional confirmation (volume spike, trend filter) before entry. 3. Test the rule on a wider universe of symbols to see whether ALAB’s behaviour is idiosyncratic.Interactive report Please review the detailed trade log, equity curve, and performance breakdown in the interactive module below.Feel free to interact with the dashboard and let me know if you’d like to tweak any parameters or explore alternative strategies.
