Dawnay Day Treveria, the AIM-listed investor in the German retail property, signalled on Monday that it is launching a strategic review that could lead to the sale of the entire company. DDT said the review was being undertaken due to the performance of its shares. The company's shares have been trading at a substantial discount to net asset value for some time and were trading 60% down on NAV on Friday. DDT's shares rose 0.025 cents to EUR 0.47 in early trading on Monday following the announcement of the review.
