Yesterday, the stock price of YOFC surged significantly, closing at HKD 271.20, an increase of 4.55%. The intraday fluctuation ranged from HKD 265.40 to HKD 283.00, indicating a strong bullish attack. The MACD daily chart has established a bullish signal, and the short-term buying power is accelerating, which is typically seen as the initial momentum for confirming a phase trend. The trading volume reached approximately HKD 4.342 billion, representing a significant increase in recent activity, with high enthusiasm for capital participation. From the opening price of HKD 274.00, slightly below the highest price, the day showed a pattern of opening low and rising high before retreating, but the closing price was still well above yesterday's close of HKD 259.40, indicating a clear bullish advantage. On the news front, global demand for AI computing power continues to explode, and optical communication, as the core infrastructure for data center interconnection, has recently gained significant market attention. Institutions pointed out that the "memory tax" effect is driving up costs across the entire AI infrastructure supply chain, while optical fibers and cables, as the "veins" of the computing power network, have seen their demand elasticity amplified in this round of capacity expansion. As the world's largest supplier of optical fiber preforms and optical fibers and cables, YOFC directly benefits from the capital expenditure growth cycle of domestic and foreign operators and cloud vendors. At the same time, the central bank's Q1 monetary policy report removed references to "cutting reserve requirements and interest rates," leading to a stabilization of short-term liquidity expectations, with funds more inclined to allocate to high-growth sectors with strong performance certainty. From a technical perspective, the current stock price has significantly risen above the short-term moving average system, with the 5-day and 10-day moving averages likely forming a bullish arrangement today. The TTM price-to-earnings ratio of 157 indicates that the market has a high premium on its growth potential, which also means that there is considerable volatility in terms of valuation. The trading volume was the biggest highlight of yesterday's performance, with over HKD 4 billion in trading volume being extremely rare among mid-cap stocks in Hong Kong, showing significant signs of institutional buying. The key variables to watch today are whether the price can hold above HKD 270 after the opening and whether there is a corresponding strength in the A-share optical communication sector. The short-term trend is biased towards bullishness, with a volume breakout resonating with the industry's high prosperity, but a sharp rise at high levels may lead to inevitable intraday fluctuations. If there is a sharp decline in trading volume after a peak today or if it breaks below the support of HKD 265, caution should be exercised regarding short-term profit-taking pressure. _This article only provides technical analysis and market information for reference and does not constitute any investment advice.
