I. Bottom Line & Directional Bias
Directional conclusion: Neutral / wait-and-see.
Three core reasons:
First, the positioning structure behind the price rebound is unhealthy. PVC main continuous (DCE.V) settled at 4906 CNY/t on September 30, up +4.3% on the day, +5.09% over 5 days, and +2.27% over 20 days, but main-contract open interest fell by 36,857 lots on the day to 1,042,564 lots, with main-contract notional open interest at CNY 26.06 billion, a daily change of -CNY 921 million. Price rising alongside falling open interest constitutes a rally on open interest cuts (short covering), rather than proactive long accumulation, casting doubt on the sustainability of the rebound.
Second, the technical position has entered a resistance zone. The settlement price of 4906 CNY/t sits at the 62.6% level of the 20-day channel of 4673–5194; the upside pivot R1 at 5070.3 is roughly 164 CNY/t away from the settlement price, exceeding half an ATR14 (125 CNY/t), making it a valid resistance reference; the downside pivot S1 is at 4861.3.
Third, fundamentals and macro transmission lack incremental bullish drivers.
Conditions that would invalidate the directional view: If the settlement price effectively holds above R1 (5070.3) and main-contract open interest recovers in tandem, the short-covering thesis is disproven and the possibility of a bullish bias must be reassessed; if the settlement price breaks below S1 (4861.3), the rebound structure is broken and the stance shifts to a bearish watch.
II. Price Action & Technicals
As of the September 30, 2026 settlement, PVC main continuous (DCE.V) settled at 4906 CNY/t and closed at 4999 CNY/t, up +4.3% versus the prior trading day's settlement, +5.09% cumulative over 5 days, and +2.27% cumulative over 20 days. On volatility, ATR14 stands at 125 CNY/t (2.5% of the settlement price, intraday full-range basis), while RV20 is 28.7%; realized volatility is at a medium-high level, implying relatively high short-term price elasticity.
Channel and pivots: The 20-day range is 4673–5194, with the settlement price of 4906 at the 62.6% position of that range, above the mid-band but not touching the upper edge. On the pivot framework, P is 4932.7, R1 is 5070.3, and S1 is 4861.3. The settlement price of 4906 is slightly below P (4932.7), about 164 CNY/t from R1 and about 45 CNY/t from S1. Measured by ATR14 = 125 CNY/t, the distance between S1 and the settlement price is less than half an ATR, so it does not serve as a valid trading-level reference; the distance between R1 and the settlement price exceeds one ATR, giving it resistance reference significance.
On the weekly timeframe, the last completed weekly candle (2026-09-21 to 2026-09-24) opened at 4725, high 4825, low 4711, closed at 4798, a weekly change of +2.02%, a confirmed bullish candle. This week (3 trading days from 2026-09-28) has not yet closed, currently quoted at 4999 (+4.19%); per weekly discipline, no weekly-level conclusion is drawn from this.
Overall, the short-term rebound has notable momentum but is approaching a resistance zone, and the rebound is driven by open interest cuts; the technical read is a rebound rather than a trend reversal.
III. Supply-Demand Balance & Fundamental Drivers
What can be confirmed is that China-related headlines within 48 hours before and after the report date were empty (N/A), with no new industrial policy or plant-event drivers.
From the macro transmission chain perspective, two paths are relevant to this instrument: First, the dollar and rates path. The dollar index at 101.46 (+0.09%) and the US 10-year Treasury yield at 5.293 (+0.72%) show the dollar and US Treasury yields strengthening in tandem, exerting a neutral-to-bearish drag on the valuation of USD-denominated international chemicals, which transmits indirectly to Chinese PVC via import costs and the international vs China market price relationship. Second, the demand expectations path. PVC downstream demand is dominated by pipes, profiles, flooring and other property- and infrastructure-related demand; changes in macro demand expectations transmit to spot and futures via downstream operating rates and procurement节奏. [Note: “节奏” = pace] — changes in macro demand expectations transmit to spot and futures via downstream operating rates and procurement pace.
It must be emphasized that the +4.3% single-day gain in the September 30 settlement price, absent clear incremental bullish drivers on the supply-demand side, is more likely driven by capital and sentiment than by substantive fundamental improvement. The fundamental dimension does not currently support a trend confirmation of the rebound, which is one of the key bases for the neutral / wait-and-see conclusion in Section I. Going forward, close attention must be paid to inventories' position relative to the five-year average, basis trends, and processing margin changes to verify the sustainability of the rebound.
IV. Positioning & Fund Flows
Positioning structure is the most cautionary dimension of this rebound. Data show PVC main continuous (DCE.V) main-contract open interest at 1,042,564 lots, down 36,857 lots on the day; main-contract notional open interest at CNY 26.06 billion, a daily change of -CNY 921 million (open interest -36,857 lots, price change +4.3%). This combination clearly points to a rally on open interest cuts, i.e., a rebound led by short covering rather than proactive long accumulation.
In terms of the nature of fund flows, short-covering rallies typically have two characteristics: first, the rebound slope is steep but sustainability depends on subsequent incremental buying; second, once short-covering momentum is exhausted, prices tend to stall near resistance or even pull back. The current price has risen to the 62.6% position of the 20-day channel and is approaching pivot R1 (5070.3), precisely the key zone for testing whether covering momentum can persist.
Regarding the confirmed divergence between positioning and price, with the price up +5.09% over 5 days while main-contract open interest fell sharply on the day, the divergence between volume/price and open interest suggests a thin capital base for this rebound, making the risk-reward of chasing longs unattractive. If price advances accompanied by recovering open interest (proactive long accumulation) emerges, the nature of the rebound may change and require reassessment; until then, the positioning structure supports a neutral / wait-and-see stance.
V. Cross-Asset & Onshore-Offshore Value
On the cross-asset dimension, the international benchmarks provided by the data are the dollar index and US Treasury yields: the dollar index at 101.46 (+0.09%) and the US 10-year Treasury yield at 5.293 (+0.72%). Both strengthening in tandem constitutes a neutral-to-bearish external environment for overall commodity valuations.
The confirmable transmission logic is: a stronger dollar and rising US Treasury yields indirectly drag on Chinese PVC valuations via import costs and the global chemicals pricing center; however, the strength of this transmission depends on import dependence and onshore-offshore linkage, and absent relative-value data it serves only as a background variable, not a basis for directional conclusions.
VI. Supply Chain & Seasonal Inventory
Based on confirmed timing information, the report date is October 1, 2026, at the start of Q4. The last completed weekly candle (2026-09-21 to 2026-09-24) closed at 4798, a weekly change of +2.02%, a confirmed bullish weekly candle; this week (from 2026-09-28) has not yet closed, currently quoted at 4999; per weekly discipline, no weekly-level conclusion is drawn from this.
Absent seasonal statistical values, this section serves only as a reminder: Q4 typically involves seasonal changes in downstream demand and year-end capital behavior, but the specific direction must be verified with inventory, basis, and operating-rate data; current data are insufficient to support a seasonal directional judgment.
VII. Scenario Analysis
Base case (55% probability): The rebound stalls near the resistance zone, with prices range-bound. Trigger conditions: short-covering momentum is exhausted, main-contract open interest no longer falls sharply, and price oscillates between pivot P (4932.7) and R1 (5070.3). Target range reference: 4861.3 (S1) to 5070.3 (R1). Corresponding action: wait and see, neither chasing longs nor shorts, awaiting clarity in the positioning-price relationship. This scenario's direction is consistent with the neutral conclusion in Section I.
Bullish scenario (25% probability): The settlement price effectively holds above R1 (5070.3) and main-contract open interest recovers in tandem (proactive long accumulation), upgrading the rebound to a trend advance. Trigger conditions: incremental long capital enters, open interest stops falling and recovers, accompanied by clear fundamental bullish drivers (e.g., inventory destocking exceeding expectations). Upside target: near the upper edge of the 20-day channel at 5194. Corresponding action: if a firm hold above R1 with recovering open interest is confirmed, a light long probe is permissible, with a stop-loss set roughly one ATR (125 CNY/t) below R1.
Bearish scenario (20% probability): The settlement price breaks below S1 (4861.3), the rebound structure is broken, and price falls back after short-covering momentum is exhausted. Trigger conditions: open interest continues to decline, price loses S1 accompanied by rising volume. Downside target: near the lower edge of the 20-day channel at 4673. Corresponding action: if a break below S1 is confirmed, a light short probe is permissible, with a stop-loss set roughly one ATR above S1.
The three scenario probabilities sum to 100%. The base case direction is consistent with the neutral conclusion in Section I; the bullish and bearish scenarios are probabilistic projections and do not constitute a second directional conclusion.
VIII. Trading Strategies & Risk Management
Given the neutral / wait-and-see directional conclusion, this section does not provide directional single-side strategies.
For institutional clients with existing positions, risk management should take priority: if holding prior longs, a stop-loss reference may be set roughly one ATR14 (125 CNY/t) below S1 (4861.3), i.e., below approximately 4736 CNY/t, to lock in rebound profits; if holding shorts, be alert to the risk of price holding above R1 (5070.3) with recovering open interest, with a stop-loss reference set roughly one ATR above R1, i.e., above approximately 5195 CNY/t.
On position sizing, given that this rebound is a rally on open interest cuts (short covering) with a thin capital base, overall position size should be kept at a low level, avoiding heavy directional bets near the resistance zone. On horizon, use 1–5 trading days as the short-term observation window, focusing on whether main-contract open interest stops falling and recovers, and whether price can effectively break above R1 or below S1. If directional confirmation signals emerge, execute according to the corresponding actions in the Section VII scenarios.
