(Sharecast News) - FTSE 250 (MCX) 24,408.29 0.28%

Big Yellow rallied after activist investor Ancora Holdings Group said the self-storage company should explore a sale.

Rate-sensitive housebuilding stocks rallied as gilt yields fell, with the 10-year yield down by more than five basis points and on course for its best daily performance in three weeks.

Barratt Redrow, Vistry and Bellway were among the top performers, with property stock Great Portland Estates also higher.

Chemring shot up after saying that its Roke subsidiary has signed a multi-year strategic partnering agreement with a major US prime contractor worth at least $170m over the first five years.

Investment manager Ashmore rose as it said assets under management edged up by $500m to $54.5bn in the first quarter, with $1.1bn of net inflows more than offsetting $600m of negative investment performance.

Softcat slid even as it hailed another year of "exceptional" growth, posting a rise in profit and gross invoiced income, driven by a "very strong", broad-based performance.
