报告引用彭博与高盛的数据称，作为最大黄金ETF的GLD，其看涨期权未平仓量（扣除看跌期权后）处于纪录水平，成为波动上行的重要"代理指 标"。 机制上，高盛表示，金价走高时，卖出看涨期权的交易商为了维持对冲被迫买入黄金，放大上涨；而一旦出现哪怕不大的回调，交易商对冲行为 可能反向，从"追涨买入"切换为"下跌卖出"，并可能触发投资者止损出局，导致进一步损失。高盛提醒，类似的"止损踩踏"在1月下旬曾出现过。 黄金市场的主导变量正在从"买不买"转向"波动有多大"。高盛认为，私营部门通过黄金看涨期权结构表达的多元化需求推升了金价波动，并在短 期内压制了央行购金节奏，但这一下降应是暂时的。 高盛分析师Lina Thomas和Daan Struyven在本周报告中指出，看涨期权需求上升迫使卖出期权的交易商在上涨过程中被动买入黄金对冲，从而机械 性放大涨幅。更关键的是，即便只是小幅回调，也可能促使交易商从"逢高买入"切换为"逢低卖出"，进而触发投资者止损单并导致进一步损失， 高盛称这一链条在1月下旬已有所体现。 在波动抬升的背景下，央行需求出现放缓，2025年12月为22吨，而目前12个月平均值为52吨。高盛强调，央行仍愿意 ...

黄金市场的主导变量正在从"买不买"转向"波动有多大"。高盛认为，私营部门通过黄金看涨期权结构表达的多元化需求推升了金价波动，并在短 期内压制了央行购金节奏，但这一下降应是暂时的。 高盛分析师Lina Thomas和Daan Struyven在本周报告中指出，看涨期权需求上升迫使卖出期权的交易商在上涨过程中被动买入黄金对冲，从而机械 性放大涨幅。更关键的是，即便只是小幅回调，也可能促使交易商从"逢高买入"切换为"逢低卖出"，进而触发投资者止损单并导致进一步损失， 高盛称这一链条在1月下旬已有所体现。 在波动抬升的背景下，央行需求出现放缓，2025年12月为22吨，而目前12个月平均值为52吨。高盛强调，央行仍愿意为对冲地缘政治与金融风险 而买入黄金，但倾向于在价格波动回落后再恢复采购，因此放缓更像"等待波动收敛"，而非趋势性转向。 对投资者而言，这意味着短期下行尾部风险上升。高盛提示，在期权需求回到纪录水平后，一些通常只会带来温和回撤的催化剂，也可能引发更 大幅度的金价回撤，估算的下行边界在4,700美元/盎司附近。但在中期，高盛仍重申看多黄金，基准情景下预计金价到2026年底缓慢上行至5,400 美元/盎司。 ...

Core Viewpoint - UBS maintains a long-term bullish outlook on gold, targeting $4,750 per ounce, but raises short-term caution due to insufficient momentum in recent price increases and heightened volatility [1][20]. Group 1: Short-term Concerns - The recent surge in gold prices is attributed to the performance of silver, platinum, and palladium rather than independent bullish factors for gold itself [1][11]. - Gold's volatility has surged to levels seen at the onset of the Russia-Ukraine conflict, diminishing its appeal as a "safe haven" asset in private investment portfolios [1][6]. - The relationship between gold and real interest rates has broken down, indicating a potential for price correction in the absence of new market stimuli [1][5]. Group 2: Market Dynamics - The current gold volatility is linked to historical data suggesting that high volatility often correlates with lower future returns [6]. - The gold-silver ratio has dropped to around 65, historically indicating weaker performance for both gold and silver in the following three months [14]. - UBS highlights that when investors aggressively pursue silver, it often signals an overheated market that requires cooling [16]. Group 3: Long-term Outlook - Despite short-term risks, UBS believes conditions for a significant decline (over 20%) in gold prices are not present, as historical patterns show such declines are typically accompanied by decreased stock market volatility and rising credit spreads [17][20]. - Key support factors for gold's long-term bullish trend include central bank purchases, stable ETF inflows, and the undervaluation of gold mining stocks [20][22][27]. - Emerging market central banks, which hold only 7-11% of their reserves in gold, are expected to continue buying during price corrections, providing support for gold prices [20].
