2月28日，和讯投顾冯禄顺表示，恒生科技指数呈现低开高走、新低反弹格局，与周四预判的反弹逻辑一致——月线级别下限5150点构成强支撑，触底后虽未出现预期中的“低开高走大阳线”，仅以止跌小阳线收复部分失地，但关键压力位已浮现。当前需紧盯两大技术信号：其一，下周一需有效站稳5日均线，若反弹连5日均线都无法突破，则受消息面扰动再创新低的风险仍存(即便新低也可能延续“新低-反弹”的震荡筑底模式)；其二，反转需等待5日均线金叉10日均线，而金叉的前提是出现一根标志性大阳线，否则在5月均线死叉10月均线的大周期下行趋势下，指数难改熊途漫漫。操作层面，当前仍处于筑底阶段，底部构建非一日之功，散户需严格遵循顺势原则，避免盲目抄底——可参考“游击战术”：若指数跌破5150点可轻仓低吸，反弹至5日均线附近即获利了结；唯有待指数重回5日均线上方、完成均线金叉且MACD翻红后，方可视为反弹行情确立。
