The pan-European STOXX 600 index gained 0.3% by 0715 GMT. Most regional bourses also traded higher, with Germany’s DAX and France’s CAC adding 0.5% each.
The benchmark STOXX 600 rose 0.9% to hit a four-month high early in Monday’s session but reversed course to close about 0.2% lower, as investors weighed the impact of a new 15% levy on most European Union goods, which is significantly higher than pre-2025 levels.
Among individual stocks, Franco-Italian eyewear group EssilorLuxottica shares jumped 5.4% after the company reported an increase in first-half operating profit despite a tariff hit.
Dutch company Philips rose almost 9% to the top of the index after the healthcare technology group lowered its tariff impact estimates following the U.S.-EU trade deal.
On the flipside, car distributor Inchcape dropped 6.3% and ranked as the top decliner after posting a first-half profit drop due to tariff impact.
