[Warrant Insight] Hang Seng Index Movement Review: The Secret Behind Warrants Surging 46% in 3 Days

On January 5, 2026, $Hang Seng Index (800000.HK)$

The Hang Seng Index closed at 26,347 points, up 0.03% on the day, with a trading volume as high as 283.462 billion. The 5-day volatility was 3.4%, and the RSI indicator reached 62. The technical indicators summarized a “sell” signal with a strength of 9. Both the Williams %R and Stochastic Oscillator showed overbought conditions and issued sell signals, while indicators such as MACD and Bollinger Bands issued buy signals, showing divergence among multiple indicators. From a technical perspective, the short-term support levels for the Hang Seng Index are 25,870 points and 25,507 points respectively, with resistance levels at 26,453 points and 27,187 points. The current probability of an upward movement is 52%, indicating intense competition between bulls and bears.

On the previous trading day (the 5th), blue-chip stocks performed unevenly. In the financial sector, HSBC Holdings (00005) and AIA (01299) both showed “strong sell” signals, with their RSIs reaching 77, indicating significant overbought pressure. Among tech stocks, Tencent (00700) and Alibaba (09988) had neutral technical signals, with some indicators suggesting overbought risks; Xiaomi Group (01810) and China Mobile (00941), on the other hand, received “buy” signals, with their share prices consolidating above support levels.

Reviewing the performance of call warrants after recent fluctuations in the Hang Seng Index clearly demonstrates the astonishing power of leverage! Two days after the unusual movement in the Hang Seng Index on December 30, 2025, related call warrants and bull contracts saw significant increases, with the BOC bull contract (53746) rising by 51% over two days, UBS bull contract (55133) increasing by 46% over two days, and J.P. Morgan call warrant (22977) and BOC call warrant (23128) also rising by 28% and 25% respectively. Meanwhile, the Hang Seng Index itself only rose by 1.87%, making the highest increase of the call warrants more than 27 times that of the index, perfectly illustrating the logic of 'small stock gains, big warrant gains.'

The logic behind this profit-making mechanism is not complex: when the underlying stock (here the Hang Seng Index) shows an upward trend, call warrants and bull contracts will follow suit with an increase, and the higher the leverage, the more significant the increase might be during the upward phase of the underlying stock. In the case of December 30, 2025, the outstanding performances were all from bull contracts and call warrants, which aligns well with the upward trend of the Hang Seng Index. Additionally, the performance of derivatives is closely related to the exercise price, premium rate, and implied volatility. Typically, the closer the exercise price is to the current price of the underlying stock and the lower the premium rate, the higher the sensitivity of the derivative to changes in the underlying stock, resulting in greater upside potential.

Based on the current market situation of the Hang Seng Index and screening of the derivatives pool, we have selected the following three targets for your reference. Investors with different holding statuses can operate accordingly:

1. J.P. Morgan Call Warrant (22977): Leverage of 12 times, exercise price at 28,200 points. Its core advantage is that it has the highest leverage and lowest premium in the current derivatives pool, making it highly sensitive to increases in the Hang Seng Index. It is suitable for investors who are optimistic about the Hang Seng Index breaking through the resistance level at 26,453 points.

BOC bull contract (60819): Leverage of 24.6 times, recovery price at 25,395 points, relatively low premium, with a certain safety margin between the recovery price and the current Hang Seng Index level. It offers high leverage while partially avoiding risks of short-term corrections in the Hang Seng Index, making it a safer choice.

BOC put warrant (20720): Leverage of 15.5 times, exercise price at 24,875 points, with both premium and implied volatility being the lowest among current put warrants. This makes it suitable for investors who believe the Hang Seng Index will not break through resistance levels in the short term and may correct, serving as a hedging or strategic tool.

Operational advice: Fellow investors who already hold the abovementioned strong call warrants or bull contracts should set stop-loss targets. For example, investors holding BOC bull contract (60819) can place the stop-loss target at 5% above the recent high point. For those who haven’t entered the market yet, it’s not advisable to chase previously soaring targets, such as related call warrants after the unusual movement on December 30, 2025, which are currently at high levels. Choosing targets with low premiums, high leverage, and reasonable exercise prices (e.g., J.P. Morgan call warrant 22977, BOC bull contract 60819) would be more prudent, as low-premium targets have lower costs when the underlying stock moves, and the risk is relatively controllable.

Finally, a key reminder of risk: intraday volatility may be due to short-term speculative capital flows. Without sustained trading volume support, the Hang Seng Index call warrants could correct at any time. Additionally, call warrants are high-risk derivatives. Before entering the market, always check the real-time premium rate and trading volume of the warrants, avoid choosing targets with low trading volume or wide bid-ask spreads to prevent being unable to close positions in time.
