(Sharecast News) - Recently-appointed Dunelm boss Nick Wilkinson doubled his holdings in the furniture retailer's stock at the end of last week, even as its shares were trading just above the multi-year lows plumbed just a handful of sessions before.Wilkinson, who became group chief executive officer on 1 February, 2018, picked-up 48,876 shares for 508.95p apiece, for a total transaction amount of roughly £248,754.That left him holding 87,731 shares in the company, equivalent to 0.04% of its share capital.On 12 July, the company reported that it was going into the end of the season with more stock than anticipated, which analysts at Peel Hunt said would result in a larger-than-expected 90 basis point drop in its full-year gross margins (Peel Hunt: -30bp) than they had penciled-in.A resulting £3m provision for those stocks and lower GMs after it was unable to hit volume supplier discounts also meant that management guided towards profits before tax for the year of £102m (consensus: £107m).Peel Hunt revised down its estimates for Dunelm's PBT for fiscal years 2018 and 2019 in the wake of the company's update, from £107m and £120.7m to £102m and £111m, respectively."The scale of downgrades remain disappointing, although much of this is a function of external conditions and unfavourable weather in Q4 rather than Dunelm specific concerns," the broker added as it reiterated its 'hold' recommendation for the shares.As of 0843 BST, shares of Dunelm were dipping 0.29% to 515.50p.Top Director BuysDunelm Group (DNLM)Director name: Wilkinson,Nick Amount
