China A-share semiconductor stocks lead gains at open; Tianpu shares up 4th straight limit

The uniformity of the move — a fourth straight limit-up for Tianpu alongside Huadong Heavy Machinery locked at the ceiling from the open — points to momentum and positioning rather than fresh fundamentals, since no single catalyst is cited. This matters most for A-share semiconductor holders, where consecutive limit-ups can signal crowded, hard-to-exit exposure as much as conviction. Whether the breadth holds beyond the open, and whether the limit-up names stay locked rather than opening up, is the open question worth tracking.
