Warrant Product Review

Regarding the review of warrant products, the two Changfei call warrants mentioned on March 27, 2026, showed significant performance in the following two trading days (up to March 31). During this period, the underlying stock Changfei rose by 6.21%, while the Macquarie call warrant (25978) and J.P. Morgan call warrant (26090) both increased by 13%, fully demonstrating the leverage effect—where the percentage gain of the call warrants significantly exceeded that of the underlying stock, allowing investors to capture stock movements with less capital and thereby amplifying returns.

Warrant product recommendations and comparisons

With the current Changfei share price at 224.8 yuan, combined with support levels at 184 yuan and 158 yuan, and resistance levels at 257 yuan and 279 yuan, investors can choose from the following four call warrants based on their risk preferences:

Societe Generale call warrant (code 26656) has a strike price of 240 yuan, with an out-of-the-money margin of only 1.18%, making it the closest product to the underlying stock among the four options. It offers effective leverage of 1.93 times, a premium of 35.75%, and a street ratio of 1.42%. The key advantage of this product is its highest sensitivity to changes in the underlying stock; theoretically, for every 1% rise in the stock price, the warrant price would follow suit with a larger movement. This makes it suitable for conservative investors looking to capture short-term volatility.

The Citi call warrant (code 26648) has an exercise price of $268.69, is 13.47% out-of-the-money, offers the highest effective leverage among the four options at 2.72 times, with a premium of 33.74%, and a street leverage ratio of 6.65%. The core advantage of this product is its highest leverage, which can significantly amplify the gains from the underlying stock's rise, making it suitable for aggressive investors betting on a breakout above the resistance level of $257.

The Macquarie call warrant (code 26620) has an exercise price of $299.90, is 26.43% out-of-the-money, provides an effective leverage of 2.28 times, with a premium of 50.46%, and a street leverage ratio of 3.31%. This product offers balanced terms with moderate leverage and premium levels, making it suitable for medium-term positioning. Investors expecting the underlying stock to break through the second resistance level at $279 may consider this option first.

The HSBC call warrant (code 27725) has an exercise price of $308.69, is 30.14% out-of-the-money, provides an effective leverage of 2.13 times, with a premium of 56.28%, and a street leverage ratio of only 0.95%. This product has extremely low street leverage, with market chips highly concentrated in the hands of issuers, offering strong price stability. It is suitable for investors who prefer low street leverage and wish to avoid the risk of large-scale selling pressure.

Two selected bullish products: For short-term trading aiming for a breakout, choose Citi 26648 $CT-YOFC@EC2609A.C (26648.HK)$ (highest leverage), for stable and close-to-price deployment, choose Societe Generale 26656 $SG-YOFC@EC2609A.C (26656.HK)$ (closest-to-price).
