“…Heston and Rouwenhorst () suggested a factor decomposition approach (the HR approach henceforth) to examine the relative importance of country versus industry factors in explaining stock return variation. The HR decomposition approach has become a popular research method in this area; it has been applied in studies such as Rouwenhorst (), Serra (), Brooks and Del Negro (), Ferreira and Ferreira (), Campa and Fernandes (), Bai and Green (, ), Lee and Hooy (), and Chou, Zhao, and Suardi (). The HR approach has also been extended in studies such as Baele, Ferrando, Hördahl, Krylova, and Monnet () and Pieterse‐Bloem, Qian, Verschoor, and Zwinkels () to decompose the country and industry factors in European corporate bonds.…”
