How long can the frenzy of Nanya Technology and Winbond Electronics last? Can the memory sector still chase higher now?

Investment Insights - "At this stage, there is indeed still a short-term bullish market to look forward to, but don't forget, whether the prices can sustain is the key factor." Recently, the memory sector has become the hottest focus in the Taiwan stock market, driving the Taiwan Weighted Index to repeatedly hit new highs. Stocks such as Nanya Technology (2408), Winbond Electronics (2344), Powerchip Semiconductor Manufacturing Corp., and Macronix International Co., Ltd. have seen their prices soar, leading the sector with great momentum. Since September, Nanya Technology has surged by as much as 70%, and Winbond Electronics has also skyrocketed over 63%, with both trading volume and market popularity exploding, becoming popular targets for capital chasing. However, this wave of collective euphoria hides a turning risk; can Micron's latest moves continue to ignite the fervor? Market Highlights on the 18th: Memory Concept Stocks Soar Yesterday (18th), memory concept stocks triggered a limit-up wave: Winbond Electronics, Powerchip Semiconductor Manufacturing Corp., and Macronix directly hit the limit-up, while Nanya Technology broke through the 80 NT dollar mark during trading. In addition, Nanya Technology's stock price reached a limit-up price of 73.7 NT dollars at one point, with the stock price strongly locked in the red throughout the day. Winbond Electronics, Powerchip Semiconductor Manufacturing Corp., Nanya Technology, and Macronix occupied the top four spots on the trading volume leaderboard, with a total trading volume exceeding one million shares, as market capital flocked in, and investor sentiment soared. Micron's Shockwave: Price Increase Expectations Ignite the Market The catalyst for this price surge came from unexpected news from Micron. Micron announced a suspension of DRAM and NAND pricing for channels and OEM/ODM, and adjusted its pricing strategy after reassessing order demand (FCST). The market quickly interpreted this as a sign that memory prices are about to enter a new round of increases. As global manufacturers reduce general memory production capacity and shift towards AI high-bandwidth memory (HBM), prices for DDR4 and DDR5 continue to rise, directly benefiting Taiwanese manufacturers like Nanya Technology and Winbond Electronics, whose stock prices surged accordingly. Emerging Concerns: Turning Risks Behind the Frenzy Despite the current supply-demand imbalance pushing memory prices up, institutional investors warn that investors need to remain vigilant. If manufacturers expand production capacity in the future while prices stagnate or decline, this emotionally driven surge may be difficult to sustain. The short-term frenzy driven by capital is hard to maintain in the long run, and investors should focus on targets closely related to memory manufacturing or module businesses. Whether the subsequent market can continue depends on whether the price curve continues to rise. In the current tense supply-demand situation, the memory sector still has upward momentum in the short term, but investors should be cautious about chasing high prices and focus on companies with solid fundamentals closely linked to the memory industry chain. By closely monitoring price trends and the movements of global manufacturers, investors can accurately position themselves in this wave of enthusiasm and avoid potential turning risks
