August 14 news
On the 13th, the spot price of styrene-butadiene rubber continued its recent upward trend, with the average difference indicator releasing a clear signal of increase. In the short term, it is supported by factors such as high international crude oil prices and increases in factory prices by manufacturers, but caution is needed against the pressure of a pullback as the 60-day cycle price is in a high range. In the medium term, the 1-year and 3-month cycle prices are at moderate levels, and given the supply and demand context of a year-on-year decrease in import volume, there is still room for price fluctuations.

III. Conclusion on Trend Direction
The price trend is clearly upward. Reasons: The 5-day, 10-day, and 20-day moving average differences are all increasing compared to the previous day, and their directions are completely consistent, meeting the criteria for a clear upward trend according to the moving average difference method; at the same time, recent international crude oil prices have been high, and Sinopec and PetroChina's Northeast Sales Company have raised the factory price of styrene-butadiene rubber by 200 CNY/ton. Downstream inquiries based on demand support merchants in raising their quotes, and the market trend continues to rise.
IV. Positional Spatial Reference
The 60-day price cycle is at a high level, with limited room for short-term gains; caution is advised regarding the risk of a pullback.
Prices for both the 3-month and 1-year cycles are at the median level, and mid-term prices still retain a certain degree of volatility.
