(Sharecast News) - Just four of the 250 constituents on the second-tier index were trading in the red on Monday afternoon, as global markets jumped on the back of a potential thawing of trade tensions between the US and China.

Media group Future was among the top risers, up 8.4% as it continued its share buyback programme with the repurchase of 65,000 shares on Monday. In December, the company announced it would buy back £55m in shares as part of its plan to return excess free cash to shareholders.

Personal computer maker Raspberry Pi was also rising 7.7% in line with the global tech sector as tariff-related uncertainty eased slightly. The Trump administration announced tariff exemptions on Chinese-made smartphones and other consumer electronics, raising hopes that Washington and Beijing may one day agree to a trade deal.

Aston Martin, which has also been dogged by tariff concerns over recent weeks, was also putting in gains of 5%.

Wealth and investments group Aberdeen, which has suffered more than most from recent market volatility, was bouncing back strongly, trading 5% higher.

Natural gas-focused exploration company Energean also impressed investors with an agreement to supply gas to Kesem Energy's new power plant in Israel, worth around $2bn in revenues over a 17-year contract period.

Software and IT services firm Kainos gained nearly 4% after saying it expects to report full-year results in line with consensus forecasts, following a solid fourth quarter that was supported by cost discipline and steady operational performance.

Leading the fallers was emerging markets-focused asset manager Ashmore which dropped 6% after reporting a 5% drop in assets under management over the first quarter of 2025.
