** Shares of Portugal's Mota Engil MOTA.LS fall 7.7% after reporting Q1 results, with one analyst pointing to possible profit-taking
** Joao Queiroz, the head of trading at Banco Carregosa, says the move may seem counterintuitive at first given the "solid results" and a "significant" contract with Petrobras
** But he notes the news come against the backdrop of the shares' strong 50% YTD run and 7.2% rise in last 12 months, which could have led some investors to take their gains
** Queiroz also points to 22% drop in Latin America turnover, which "may have generated doubts and uncertainties about the continuity of the operating rhythm in the region"
** The shares are on track for their worst day since January 7, when they closed 10.5% lower
