SHARES in Optos have fallen almost three per cent in spite of a positive note from a broker.

The optical imaging business, which is due to publish its results next week, saw Canaccord Genuity raise its target price for Optos stock from 231p to 249p. However, the shares closed 6p lower at 208. Canaccord kept its buy rating on the stock and said it expects Optos to benefit from the increasing market penetration of its Daytona device while also gaining further sales with two new products.
