The MACD daily line formed a death cross below the zero axis, indicating that the previously weak bullish momentum is further diminishing, and bearish momentum is accelerating. The stock price's single-day decline of nearly 7% significantly deviates from the recent fluctuation range, with the market showing concentrated selling pressure. In terms of volume, the trading amount has increased compared to previous periods, indicating that some investors are choosing to exit at this level. On the news front, the Hong Kong stock automotive sector is under overall pressure, with BYD's shares falling nearly 2% to HKD 101 yesterday, and Geely Auto also experiencing a slight decline, with the sector showing weak linkage. In the global macro environment, WTI crude oil has returned to a high of USD 105, putting pressure on the cost side for automotive manufacturers, and the market's profit margin expectations for new energy vehicle companies have been revised downwards. Meanwhile, Federal Reserve Bank of New York President John Williams stated that there is no reason for a rate cut in the short term, and the high-interest-rate environment continues to suppress the valuations of growth assets. As SERES is a major manufacturing partner of the Aito brand, its sales data and the progress of Huawei's smart car business are focal points for investors, but there has been a lack of clear positive catalysts recently. From a technical perspective, the stock price has fallen below several short-term moving averages, and the MACD's death cross below the zero axis confirms a bearish mid-term trend. If the stock cannot quickly recover the HKD 72-73 range in the following trading days, bearish inertia may push the stock price further down to seek support around HKD 65" datetime: "2026-05-06T01:00:00.000Z" locales: - [zh-CN](https://longbridge.com/zh-CN/news/285173968.md) - [en](https://longbridge.com/en/news/285173968.md) - [zh-HK](https://longbridge.com/zh-HK/news/285173968.md) --- # Pre-market trend | SERES (9927.HK) plummeted nearly 7% on 5/5 with increased volume, is it an acceleration of short selling or a release of panic? Yesterday's close saw SERES stock price sharply decline by 6.97%, closing at HKD 70.10, with a trading volume of HKD 93.03 million, making it the most active stock among those triggering a death cross signal. The MACD daily line formed a death cross below the zero axis, indicating that the previously weak bullish momentum is further diminishing, and bearish momentum is accelerating. The single-day decline of nearly 7% significantly deviates from the recent fluctuation range, with the market showing concentrated selling pressure. In terms of volume, the trading amount has increased relative to previous periods, indicating that some investors are choosing to exit actively at this price point. On the news front, the Hong Kong stock automotive sector is under overall pressure, with BYD shares falling nearly 2% to HKD 101 yesterday, and Geely Auto also experiencing a slight decline, with the sector showing weak linkage. In the global macro environment, WTI crude oil has returned to a high of USD 105, and rising oil prices are putting pressure on the cost side for automotive manufacturers, leading to a downward revision of profit margin expectations for new energy vehicle companies. Additionally, Federal Reserve Bank of New York President John Williams stated that there is no reason for a rate cut in the short term, and the high-interest-rate environment continues to suppress the valuations of growth assets. As SERES is a major manufacturing partner of the Aito brand, its sales data and the progress of Huawei's smart car business are focal points for investors, but there has been a lack of clear positive catalysts recently. From a technical perspective, the stock price has fallen below several short-term moving averages, and the MACD zero-axis death cross confirms a bearish mid-term trend. If the stock cannot quickly recover the HKD 72-73 range in the following trading days, bearish inertia may push the stock price further down to seek support around HKD 65. However, a nearly 7% single-day decline is already a significant adjustment, and after being oversold in the short term, a technical rebound cannot be ruled out, with the key being whether the volume can quickly shrink to confirm the release of panic. In the A-share market, the performance of the automotive sector and the linkage with Huawei-related concepts will directly affect the opening rhythm of SERES in the Hong Kong stock market. The short-term trend is biased towards bearishness, with technical signals resonating with sector pressure. However, after a sharp decline, short-term volatility has increased, and if there is a stabilization with reduced volume or sector positive drivers, the weak pattern may be temporarily interrupted. Currently, there is a high level of uncertainty, and observation is key. _This article only provides technical analysis and market information for reference and does not constitute any investment advice.
