Two rubbish theory of value candidates – Accesso and Superdry may be at an early stage of a dramatic turnaround

One of my favourite themes is the rubbish theory of value. Shares fall to a point where they are treated as rubbish by the stock market. An exciting example was Ashtead, which became almost worthless in 2003 and is now valued at over £22bn. Two candidates for rebirth that look exciting now are global retailer, Superdry, after the return of founder, Julian Dunkerton as CEO and Accesso, which last year was in danger of breaching its loan covenants but this year is poised to ride the recovery as visitors return to theme parks and other outdoor events using the group's solutions.
