Backtest China Yuchai International Stock Performance
The performance of CYD after a 9% intraday surge from 2022 to now has been backtested, but the strategy yielded no events because the required trigger never occurred. Here's an analysis based on the backtest results and market conditions:1. Backtest Results: The backtest for CYD's performance after a 9% intraday surge from 2022 to now using the "CVI – 9 % Intraday-Surge Strategy" showed no events, as the share price never closed at least 9% higher than the previous day's close.2. Market Conditions: China Yuchai International (CYD) has faced a mixed outlook with both margin improvement and revenue decline. Despite an improvement in gross profit margin and operating profit margin, the revenue growth outlook has been disappointing, with a forecasted drop in revenue for FY 2022.3. Strategic Considerations: The strategy's inability to generate events suggests that it may not align with the stock's actual price movements under current market conditions. This could be due to factors such as market trends, company fundamentals, or external factors affecting CYD's stock price.In conclusion, the backtest indicates that the "CVI – 9 % Intraday-Surge Strategy" would not have yielded any trades based on CYD's performance from 2022 to now, likely due to the strategy's stringent criteria not being met under the prevailing market conditions.

Bullish Momentum Intact – Key Levels to Watch for Next Move
China Yuchai’s acquisition of NYDK cements its position in critical powertrain components, while technicals suggest continued upside potential.

Sector leader boldBorgWarner (BWA), up 1.07%, reflects broader auto components strength, but Yuchai’s strategic move differentiates it.
