Aim-listed Boohoo had long been the upstart to the more established Asos, before surpassing it in terms of market cap last year. Today the shares, already dented its shares this week, fell a further 37p or 12% to 260p today. On top of yesterday’s 23% plunge, that meant the company had lost £1.5 billion off its market cap in two days and its value, at £3.27 billion, has slipped marginally below rival Asos at £3.31 billion.
