August 20 news
Recently, the styrene-butadiene rubber market in China has been driven by high and firm international crude oil prices, enhanced upstream cost support, and continuous price adjustments by manufacturers, leading to a sustained increase in spot prices. The average difference indicators show a clear signal of an upward trend. Considering the position in the price cycle, there is ample short-term momentum for further increases, but attention should be paid to the risk of a pullback from the high levels.

II. Signal State Determination
The changes in the three differences (5-day, 10-day, and 20-day) compared to the previous day are all positive, indicating a clear upward trend.
III. Conclusion on Trend Direction
The price trend is clearly upward. Reason: From the perspective of the average difference indicator, the 5-day, 10-day, and 20-day average differences are growing positively in sync, meeting the criteria for a clear upward trend in the average difference method; at the fundamental level, the high and firm position of the international crude oil market provides strong cost support for styrene-butadiene rubber. Since August 14, companies such as the Northeast Sales Company of China National Petroleum Corporation and Sinopec have continuously raised the factory prices of styrene-butadiene rubber, with a cumulative increase of 500 CNY per ton, driving merchants in regions like Jiangsu, Zhejiang, and Northeast to follow suit by raising their quotations. The spot market trading atmosphere is relatively strong.
IV. Positional Spatial Reference
The price is at the median of the 1-year cycle, and there is still some support for further upside potential.
The 3-month cycle price is at a medium-to-high level, with prices showing a relatively strong trend in the short term.
The 60-day cycle price is at a high level, and in the short term, there is a need to be cautious of the risk of a pullback from these highs.
