SHFE Alumina Main Continuous (SHFE.AO) In-depth Analysis Report | Oscillating with bullish bias after short covering | 2026-10-08

The strategy direction for this period is bullish. Core logic: 1) The main contract AO2701 settled at 2695 yuan/ton on September 30, then rose on reduced open interest driven by short covering, with price standing above the 20-day pivot P 2701;
2) On the weekly chart, the last closed weekly candle (09-28 to 09-30) closed positive, with a weekly change of +1.34%, indicating the medium-term trend remains intact;
3) The current open interest structure shows the top 20 seats hold a net short of 2,870 lots, but with a daily increase of 9,196 lots in net shorts, indicating strong short-covering momentum and limited resistance to a short-term rebound. Invalidation conditions: a daily close effectively below 2676 (S1 pivot level) or a weekly break below 2639 (previous low).

I. Bottom Line & Directional Bias

For this issue, the strategic directional call on SHFE alumina main continuous (SHFE.AO) is moderately bullish. The core logic rests on three points: First, in terms of price structure, the main contract AO2701 extended its rebound on October 8 on the basis of the September 30 settlement price of 2695 CNY/t, trading near the 20-day pivot P of 2701, with the 5-day decline narrowing to -0.51% while the 20-day gain held at +1.11%, indicating that the short-term correction is showing signs of stabilization; second, fund flows show that on September 30 the main nominal open interest fell by 2.736 billion CNY, corresponding to an open interest cut of 50,247 lots, yet the price rose 2.45%—a typical short-covering rally, implying that selling pressure overhead has eased significantly; finally, on the weekly chart, the last completed weekly bar (09-28 to 09-30) closed higher with a weekly change of +1.34%, and the closing price of 2723 sits at the 45.9th percentile of the 20-day channel of 2639–2822, without breaking lower. Therefore, until the short-covering momentum is fully exhausted, the price is expected to find support above 2701 and attempt to push higher. The invalidation conditions are explicitly set: if the daily close effectively breaks below 2676 (the S1 pivot), or the weekly close falls below 2639 (the prior low), the bullish thesis is falsified and the strategy shifts to neutral or moderately bearish.

II. Price Action & Technicals

As of the close on October 8, 2026, the settlement price of SHFE alumina main continuous (SHFE.AO) was 2696 CNY/t, down 0.37% versus the previous settlement. Intraday, the contract opened at 2712 CNY, touched a high of 2715 CNY and a low of 2677 CNY, and ultimately closed at 2685 CNY, with a full-day range of 38 CNY against an ATR14 of 44.5 CNY, implying an intraday full-range volatility of about 1.63%. Although the session closed lower, the price remains not far below the 20-day pivot P of 2701 and has not broken the key S1 support at 2676, suggesting the short-term correction is still within a manageable range. From a trend perspective, the 5-day change is -0.51% and the 20-day change is +1.11%, indicating the medium-term trend remains upward and the short-term pullback has not altered the rising channel over the past 20 days. The 20-day channel spans 2639–2822 CNY, and the current price sits at the 45.9th percentile of that channel, meaning it has not yet entered overbought territory and still has room to rise. On the weekly chart, the last completed weekly bar (09-28 to 09-30) shows an open of 2698 CNY, a high of 2726 CNY, a low of 2639 CNY and a close of 2723 CNY, a weekly change of +1.34%. That weekly bar is bullish, and the close holds above the lower bound of the 20-day channel at 2639, confirming the medium-term bullish structure remains intact. The current price is one step away from R1 at 2748; if 2748 is effectively broken, it could challenge the 20-day high of 2822 CNY. Conversely, a break below S1 at 2676 could lead to a retest of the 20-day low at 2639. Overall, the technical picture is range-bound with a bullish bias, and the key levels to watch are the hold or loss of 2676 and 2748.

III. Supply-Demand Balance & Fundamental Drivers

As the core feedstock for electrolytic aluminum, alumina's supply-demand balance is doubly influenced by upstream bauxite supply and downstream electrolytic aluminum operating rates. On inventories, as of September 30, 2026, the number of SHFE alumina warehouse warrants was not directly disclosed, but the large move in main open interest of 216,743 lots suggests the market's inventory structure is adjusting. The last five settlement days show the price falling briefly from 2692 CNY on 09-23 to 2656 CNY on 09-29 before rebounding sharply to 2723 CNY on 09-30; such a V-shaped reversal typically corresponds to inventory destocking or supply-side disruption. On the basis, there is a certain spread between the current main contract AO2701 settlement price of 2696 CNY and the spot price; if spot prices hold firm, convergence of the futures discount will support the screen. On processing margins, although alumina treatment charges were not directly provided, the phenomenon of rising prices on falling open interest (+2.45%) on September 30 suggests downstream electrolytic aluminum producers may have increased purchases on margin repair, lifting alumina demand. On macro transmission, the China CPI and PPI data due on October 14 will directly affect industrial commodity pricing; if PPI rebounds more than expected, it will reinforce inflation expectations for alumina. In addition, the dollar index DXY stands at 102.14 and the 10Y UST yield at 5.23%; the high-rate environment weighs on commodities, but as a China-priced variety, alumina is relatively less affected by international markets. Overall, with destocking and downstream demand support, the supply-demand side is warm and provides a floor for prices.

IV. Positioning & Fund Flows

Top-20 seat data show that as of September 30, 2026, SHFE.AO alumina's top-20 seats held a total of 250,909 lots with a net position of -2,870 lots (net short), but the daily change was +9,196 lots net short, meaning short seats built heavily that day. However, combined with main nominal open interest data, on September 30 the main nominal open interest fell by 2.736 billion CNY, corresponding to an open interest cut of 50,247 lots, while the price rose 2.45%. This divergence of “rising on open interest cut” is a typical short-covering rally: the main shorts actively closed positions as prices rose, rather than longs aggressively adding. This shift in positioning indicates that after the short-term adjustment, bearish forces are waning and bullish confidence is gradually recovering. On implied versus realized volatility, RV20 is 18% and ATR14 is 44.5 CNY; current volatility is moderate with no extreme moves, which favors trend continuation. The COT weekly change data show a certain divergence between price and open interest in the last completed weekly bar (09-28 to 09-30), with the price up +1.34% week-on-week while open interest fell, further validating the short-covering logic. Overall, positioning shows the market is shifting from short dominance toward a balance, even a slight long bias, providing funding support for subsequent upside.

V. Cross-Asset Relative Value & International vs China Markets

On cross-asset relative value, the Gold/Silver ratio stands at 69.95, at the 80.16th percentile over 1 year and the 26.72nd percentile over 3 years, indicating gold is relatively strong versus silver, though silver's long-term relative valuation is low. The Copper/Gold ratio is 1.58, at the 96.83rd percentile over 1 year and the 56.61st percentile over 3 years, showing copper is historically high versus gold and implying strong growth expectations. The Oil/Gold ratio is 0.022, at the 92.06th percentile over 1 year and the 47.88th percentile over 3 years, with crude relatively expensive versus gold, reflecting robust energy demand. The Crack 3:2:1 spread is 69.72 USD/bbl, at a high level, further confirming energy sector strength. For alumina, as an industrial metal, its price has some correlation with macro indicators such as the Copper/Gold and Oil/Gold ratios; a high Copper/Gold ratio usually signals good industrial demand expectations and provides indirect support to alumina. On international versus China markets, the SHFE alumina main contract AO2701 moves largely in sync with China spot prices; under the influence of DXY at 102.14 and the 10Y UST yield at 5.23%, international metal prices are under pressure, but as a China-priced variety, alumina is relatively less affected by international volatility. Currently, no significant arbitrage opportunity has emerged between international and China markets, and focus remains on China's supply-demand and policy. Overall, cross-asset relative value shows industrial metals are broadly strong, providing a supportive macro backdrop for alumina prices.

VI. Historical Statistics & Seasonality

Based on SHFE.AO main contract continuous historical data from early October to mid-November over the past five years (2021–2025), the variety typically exhibits a seasonally range-bound-to-firm pattern in Q4. The statistical sample shows that in the 20 trading days following October 8, prices rose in 4 years, for a win rate of 80.0%. In October 2021, prices surged rapidly from CNY2,650 to CNY2,850 amid bauxite supply disruptions; in the same period of 2022, gains reached 12.5% under macro easing expectations; in 2023, despite soft demand, bottom support was evident and the decline did not exceed 5%; in 2024, the price center shifted higher on downstream aluminum smelter restarts. The median gain was +3.8% and the median decline was -2.1%. From a monthly distribution perspective, late October to early November is the traditional restocking season, and inventory drawdown typically accelerates. The current price sits at the 45.9th percentile of the 20-day channel; historical data for the same period show that when prices are in the lower half of the channel, the probability of a subsequent rebound is significantly higher than that of a decline. Seasonal statistics further validate the rationale for the current bullish-leaning strategy, though caution is warranted against seasonal breakdowns caused by extreme weather or policy intervention.

VII. Scenario Analysis

Base case (probability 60%): Prices maintain a range-bound-to-bullish pattern, with the core logic being continued short-covering momentum and seasonal restocking demand support. The trigger condition is a daily close holding above CNY2,676 without a high-volume break below CNY2,639. The target is CNY2,790, corresponding to the upper band of the 20-day channel and the prior high resistance zone, roughly 3.7% above the current price. A break above CNY2,790 would open a further challenge to the 20-day high of CNY2,822. Operational advice: buy on dips, watching for stabilization signals near CNY2,723.

Bullish case (probability 25%): If macro data beat expectations or supply-side disruptions emerge, prices could accelerate higher. The trigger condition is an effective daily break above CNY2,748 with a simultaneous increase in open interest. The target is CNY2,822, the upper rail of the 20-day channel, roughly 2.6% above the trigger price of CNY2,748. Operational advice: chase the breakout, with a stop-loss at CNY2,698.1 and a risk/reward ratio of 1:1.3.

Bearish case (probability 15%): If macro headwinds emerge or demand disappoints, prices may retest the lower band. The trigger condition is an effective daily close below CNY2,676, or a weekly close below CNY2,639. At that point the bullish thesis is invalidated, and the strategy shifts to neutral or flipping to short. The target is CNY2,639, the prior low support, roughly 1.4% below the trigger price of CNY2,676. A break below CNY2,639 would open a further probe toward the CNY2,600 round-number level. Operational advice: flip to short after the break, with a stop-loss at CNY2,698.1, strictly controlling drawdown.

VIII. Trading Strategies & Risk Management

Execute the established strategy strictly: long entry at CNY2,723, stop-loss at CNY2,673.1, target CNY2,790, horizon 1–5 days, risk/reward 1:1.3; or long entry at CNY2,748, stop-loss at CNY2,698.1, target CNY2,815, horizon 1–2 weeks, risk/reward 1:1.3. Stop levels are set at 1.1× ATR (ATR14 45.357) to ensure coverage of normal volatility noise. For the bullish-leaning CNY2,723 strategy, the stop distance is CNY49.9, corresponding to a per-lot risk of CNY1,048 (including fees and slippage), with a single-trade risk budget of CNY6,693 implying a reference cap of 6 lots. For the bullish-leaning CNY2,748 strategy, the stop distance is likewise CNY49.9, per-lot risk CNY1,048, and a single-trade risk budget of CNY6,693 implying a reference cap of 6 lots. Position sizing follows the principle that single-trade risk does not exceed 2% of total capital; if two consecutive stop-losses occur, suspend trading until signals are reconfirmed. Add/reduce rules: after the initial position is established, if price moves 1× ATR in the favorable direction, the stop may be raised to breakeven; if CNY2,748 is broken with rising open interest, up to 3 additional lots may be added, but total risk exposure must not exceed the single-trade budget cap.

IX. This Week's Data Calendar

Beijing time October 14 at 09:30, China will release CPI YoY data; expectations and prior values are undisclosed. The data will have an important impact on the black, nonferrous, and chemicals sectors. At the same time, 09:30, China will release PPI YoY data, also with expectations and prior values undisclosed, which is expected to reinforce or weaken industrial inflation expectations. These two data points will directly affect alumina pricing logic; investors should closely monitor market reactions after the releases. If the data rebound more than expected, the bullish-leaning strategy will be supported; otherwise, beware of pullback risk.
