Coherent (COHR) is back in focus after Reuters reported that the Trump administration and the FCC are planning restrictions on Chinese optical transceivers, a move that could redirect AI data center demand toward U.S. suppliers.

The Reuters report appears to have arrived on top of an already strong run for Coherent, with a 7 day share price return of 47.81% and year to date share price return of 68.90%. Over a longer horizon, total shareholder return of 206.32% over the past year and a very large 3 year total shareholder return suggest momentum has been building rather than fading.
