STAR 50 Index Rebounds Over 1% After Morning Drop of More Than 3%

The intraday reversal matters less for the index level than for where the buying concentrated: semiconductor equipment and optical chips, the segment most exposed to domestic substitution and export-control headlines. That the rebound was led by these names, rather than broad-based, suggests positioning around policy and supply-chain news rather than a change in the sector's fundamentals. Whether that leadership holds into the close, or fades like the morning selloff, is the open question.
