Nomads will next Tuesday be trekking along the south bank of the Thames to the annual conference hosted by Lawrence Graham, the law firm, at its headquarters in the More London development.

The programme for nomads – the nominated advisers that bring companies to the Alternative Investment Market – includes a session entitled “Mad and bad – market abuse and disclosing bad news”. This week provided a perfect case study of bad news when the London Stock Exchange publicly censured Astaire Securities and fined it £225,000 over the flotation of Worthington Nicholls, the air conditioning specialist.
