Over the last 18 months, the Portuguese capital markets have been stirred into life by a number of interesting trades, many involving the acquisition of shares in Portuguese-listed companies by foreign investors.

This trend reached a new high in recent weeks when Brazilian industrial group Companhia Siderurgica Nacional (CSN) launched a takeover bid for Cimpor, a major Portuguese-based cement company. Two other Brazilian groups (Votorantim and Camargo Correa) have taken a significant interest in Cimpor, acquiring stakes in the company with deals for €1bn (£893m) and €1.3bn (£1.2bn) and generating additional excitement in the market.
