Pre-market trend | KNOWLEDGE ATLAS (2513.HK) on 5/14 saw a huge volume spike followed by a pullback, are the bullish signals reliable?

Yesterday's closing saw a significant pullback in the stock price of KNOWLEDGE ATLAS, which briefly touched an intraday high of HKD 1,229 before ultimately closing at HKD 1,090, down 5.22% from the previous trading day, with an intraday volatility of up to 13.8%. Despite the weakening closing price, the MACD on the daily chart confirmed a bullish signal above the zero line, which typically indicates that the medium-term trend remains strong, and the short-term pullback appears to be a rhythmic fluctuation triggered by profit-taking. The trading volume reached approximately HKD 1.852 billion, ranking among the top in the market, with intense capital competition. After a gap up at the opening, selling pressure quickly suppressed the price, significantly amplifying the long-short divergence at high levels. On the news front, the global AI large model sector continues to heat up. Recently, Alibaba and Tencent both released their financial reports on the same day, emphasizing their investments in AI and commercialization progress, with Alibaba Cloud targeting AI revenue of HKD 30 billion by the end of the year, and Tencent quantifying its AI cost investments for the first time. As one of the leading large model companies in China, KNOWLEDGE ATLAS's valuation logic in the AI foundational model field is highly correlated with these tech giants. Additionally, external catalysts such as U.S. President Trump's visit to China and NVIDIA's upcoming financial report are continuously boosting the overall enthusiasm in the AI sector, but the short-term gains have led some funds to choose to cash out at high levels. From a technical perspective, KNOWLEDGE ATLAS opened at HKD 1,135, lower than yesterday's close of HKD 1,150, indicating a weak opening, and after dipping to a low of HKD 1,070 during the day, it stabilized somewhat, suggesting that there is a certain level of support in the HKD 1,070-1,090 range. If the subsequent trading days can stabilize above HKD 1,070 with reduced volume and close with a bullish candle, it is expected to confirm the effectiveness of short-term support
