description: "$Pfizer(PFE.US) and $LONGBIO-B(01779.HK) both rose slightly, while $Regencell Bioscience(RGC.US) fell slightly—it's all minor moves in the pharma sector. The standout is $Intuitive Surgical(ISRG.US): the stock price has barely moved, but it has been lingering below the 50-day moving average for a while, with a 14-day RSI in the 30s. It's rare for a medtech leader to offer such a prolonged window of weakness. The penetration logic for surgical robots hasn't changed at all; what's been discounted is the valuation, not the fundamentals. Is this kind of slow bleed in a blue-chip stock the "good company at a discount" scenario from the textbooks? I personally think it is, but the discipline for left-side accumulation is to build the position in three tranches, don't go all-in at once. The bottom for a blue-chip can grind longer than you think 🤔"
