On August 3, Lumentum fell 4.1% in regular trading, trading at $672.29/share, with turnover of $119 million. On the news front, the aftermath of concentrated forced liquidation in momentum stocks continues to weigh on the optical communications sector.

The high-beta momentum factor has cumulatively retreated over 40% within 26 trading days, forcing leveraged funds into concentrated position reductions. As a sector with outsized prior gains, optical communications stocks bore the brunt of selling pressure. Meanwhile, company insiders have cumulatively sold approximately $38.86 million in shares over the past three months, further suppressing market sentiment. Although Microsoft's earlier strong earnings briefly reignited confidence in AI infrastructure spending and triggered a sector rebound, the recovery proved short-lived.

Within the Communication Equipment sector, peers declined in tandem: Applied Optoelectronics down 6.45%, Ciena down 4.99%, Nokia down 3.77%, Arista Networks down 2.73%, and Cisco down 1.56%.
