These past two days, tech stocks have dealt me another blow. Hesai was all the rage not long ago with everyone shouting about the lidar revolution, but in no time, its stock price has been plummeting, and the sentiment has completely cooled off. Richtech Robotics was just hyped up yesterday with its AI theme, only to be abruptly awakened by short sellers today, leaving short-term traders feeling like they've been fleeced again. IonQ's quantum dream is too far off, and before the acquisition could even be digested, it's already been hammered by capital. So much for innovation leading the way—it feels more like innovation digging pits... Lately, keeping an eye on these high-tech concepts has been like riding a roller coaster.
