Diploma PLC stock price drops 3.5% as Trump tariff threat jars FTSE 100 mood
Diploma PLC shares fell 3.5% to 5,488 pence by midday in London, retreating from last week’s record, as U.S. tariff threats rattled markets. The FTSE 100 dropped 0.6% after President Trump warned of new tariffs on Britain and Europe starting Feb. 1. European stocks also declined, with the STOXX 600 down about 1%. Diploma, which earns nearly half its revenue in the U.S., gave no new company updates.
