Shengyishe published its September 28 sulfur trend analysis through Sina Finance at 09:01 China time, using the house 均差 framework to score short and medium momentum.
The table compared September 27 values to September 26 for 5-day, 10-day, and 20-day 均差, showing -6.67 versus -13.33 on the 5-day line, 16.00 versus 25.83 on the 10-day line, and -194.59 versus -221.90 on the 20-day line.
The resulting (+, -, +) combination mapped to a pullback signal with a mildly bullish bias in Shengyishe's taxonomy rather than a straight buy or sell flag.
The desk conclusion labeled price action oscillation because the three horizons did not all move in the same direction versus the prior session.
Position bands placed 60-day and three-month prices in the first tier for limited near-term downside while the one-year band sat in the fourth tier, capping longer upside in the same note.
That technical read landed hours before the rawmex screen printed 7,735.67 yuan per tonne at 16:00, a modest daily lift that fits an oscillating tape more than a breakout.
September 23 and September 24 national 基准价 articles at 7,752.33 yuan remain the latest morning series prints, so trend math and headline benchmarks can diverge until Monday articles catch up.
SMM's August import tables showed elemental sulfur arrivals down 65 percent year on year, a demand and supply backdrop that can keep technical signals choppy even when spot ticks up.
BC Insight's September Harrisson commentary described Middle East monthly sulfur exports below 1.0 million tonnes since March 2026, a world supply constraint that does not automatically translate into higher Chinese spot when port stocks look heavy.
Alberta July 2026 closing inventory above 11.1 million tonnes in AER ST3 keeps Canadian block stocks measured while Chinese desks debate oscillation versus trend.
Vancouver's 2025 sulfur export total at 3.51 million tonnes, up 5 percent year on year, shows Pacific clearance capacity when Chinese buyers return to the stem.
Desk read: treat the September 28 trend note as methodology commentary on momentum, not a substitute for the rawmex closing print or licensed PRA weekly assessments.
