Why Is AXT (AXTI) Stock Price Down 6.18% Today, Sep 23? Profit-Taking and Weaker Chip Stocks Push AXTI Lower

AXT (NCSKAXTI2USD) fell 6.18% amid a broader semiconductor risk-off session driven by higher Treasury yields and a sharp rise in oil, which typically compresses growth/tech valuation multiples. The decline also reflects profit-taking after the stock's recent rally tied to S&P SmallCap 600 inclusion, with no clear company-specific negative catalyst flagged. Near-term trading is likely to stay sensitive to rates, sector sentiment, and index-related positioning.
