ESTUN traded in a narrow range of HK$17.000-HK$17.190 during the morning session, opening at HK$17.000 and last at HK$17.100, up ~7.1% from the previous close of HK$15.970, driven by the sustained market reaction to its Q1 net profit surge of 720% YoY to HKD 110.9 million and the robot acquisition plan. Net profit margin improved to 8.04% from 1.47% in Q4, though the stock trades at a lofty PE of 115.13x. The price remains 34.68% below the 52-week high of HK$26.18 and sits below both the 20-day MA (HK$19.581) and 60-day MA (HK$18.138), indicating technical weakness in the medium term. Recent news, however, highlighted concerns over profit sustainability after a previous 10% plunge following the strong profit forecast, capping today's rally.
