Before A-share bull stocks launch, RPS120 typically first breaks the 80 percentile 1-4 weeks prior to the official price launch. This article reviews the candlestick charts and RPS curves of 8 recent A-share major bull stocks, verifying the core CANSLIM principle that “RPS ≥ 80 is a common characteristic of strong stocks.” Among them, Hongjing Technology recorded a range gain of up to +1981%, Guangzhi Technology +1846%, and Jin’an Guojie +1354%, all of which entered their main uptrend after RPS broke through 80.
The following 8 A-shares all come from real historical data in the RPS Stock database. Each chart shows a weekly candlestick chart above and the RPS120 curve below, with a yellow dashed line marking the time when RPS first broke the 80 percentile (the “launch signal”) and triangles marking the corresponding stock-price position at that time.

Review and Analysis
Zhongchuan Special Gas (688146) is the leading domestic semiconductor specialty gas stock, benefiting from the accelerated domestic substitution and semiconductor expansion cycle. From the RPS curve, it can be seen that the stock first broke through the 80 percentile in RPS120 in 2024 year 7 month, with stock price approximately ¥29.79, Thereafter, the stock price continued to rise, reaching a high of over ¥420, with an interval gain of +685.8%. The RPS signal appeared approximately 2-3 months ahead of the stock's main uptrend, which is a typical case of «RPS leading prices». It is worth noting that after a brief pullback in RPS in 2024 year 8-10 month, it strengthened again, forming a «second confirmation» signal, which is often a safer time to add positions.
Review and Analysis
Hongjing Technology (301396) is a highly elastic stock in the A-share semiconductor equipment sector. RPS120 first broke through 80 in 2025 year 6 month, with stock price approximately ¥42.81, subsequently driven by the domestic substitution wave in semiconductor equipment, the stock price reached a high of over ¥285, with interval gains as high as +1981.5%, which is the largest gain in this review. This case fully illustrates that in the A-share technology growth sector, breaking through RPS 80 is often an important signal for the start of the main uptrend, combined with sector prosperity analysis, it can greatly improve the certainty of stock selection.
Review and Analysis
Optics Technology (300489) benefits from the explosive demand for optical devices due to AI computing power infrastructure construction. RPS120 first broke through 80 in 2026 year 4 month, with stock price approximately ¥68.31 when the signal appeared, subsequently the maximum interval gain reached +1846%. This case is a typical example of RPS stock selection in the AI theme rally: In the early stages of the AI wave, RPS first reflected the gathering of funds, providing investors with quantitative signals earlier than the general public's understanding.

Jin'an Guoji (002636) is the leading PCB copper clad laminate, benefiting from the surge in demand for high-end PCB materials from AI servers and high-frequency communications. RPS120 first broke through 80 in 2025 year 7 month, with stock price approximately ¥12.44 at signal time, subsequently interval gains reached as high as +1354.2%. This case illustrates that RPS stock selection is not only applicable to high-visibility large-cap stocks, but also has extremely strong predictive value in small and medium cap growth stocks.
Review and Analysis
Titan Shares (003036) is a semiconductor specialty material supplier, in the same semiconductor materials sector as Zhongchuan Special Gas. RPS120 first broke through 80 in 2025 year 6 month, subsequently interval gains reached +788.3%. It is worth noting that the RPS signals of Titan Shares and Hongjing Technology appeared on the same day (2025-06-16), indicating an overall RPS resonance in the semiconductor materials sector at that time point, such «sector RPS resonance» often foreshadows the launch of sectorial行情.
