Investors took flight when Sprue Aegis, the AIM-listed smoke alarms-maker, said it expects a lower annual operating profit of £8.3 million after agreeing to pay its supplier DTL more to help it deal with higher labour costs in China. Shares fell 28.6p to 263.9p.
Tech investor Mercia Technologies, up 0.4p at 41.9p, spent £11 million on Enterprise Ventures, a venture capital firm which has cashed in on eight AIM floats, including OptiBiotix, the LSE’s best-performing non-resources share last year.
