Superdry owner SuperGroup was retreating one day after revealing its quarterly sales had soared by a quarter, following strong demand across the group, in particular womenswear, as it moves into the autumn period with confidence.The fashion retailer said total group sales for the quarter to July 28th increased by 25.7% to £75.0m, after what the company described as a 'solid trading performance in line with management expectations'.The John Laing Infrastructure Fund was also down after it unveiled plans to raise up to 240m pounds through the issue of 218.3m shares at between 107p and 111p. The funds will be used to reduce debt and to buy a package of three public-private partnership projects for £103m.Meanwhile, travel group Thomas Cook was on the rise having dropped earlier in the week as a result of read-across from Ryanair, which issued a profit warning. Lancashire Holdings was also up after announcing that following a special general meeting the previous day its shareholders had voted through its proposal to acquire Cathedral Capital, a privately owned Lloyd's insurer.
