English to Greek Bus/Financial Economics

Βρήκα την επεξήγηση στα Αγγλικά, αλλά δυσκολεύομαι με την απόδοση στα Ελληνικά. Η πρότασή μου είναι ως εξής:"we have moved to an overweight position in Industrials and specialist companies within the Chemicals sector in anticipation of lower raw materials costs in 2006"
Overweight
Usually refers to recommendation that leads an investor to increase their investment in a particular security or asset class. The increase is usually with respect to a benchmark. Suppose that U.S. equities compose 40% of the benchmark portfolio. If one thinks the U.S. will outperform, the investor may increase the exposure to U.S. equity to more than 40%.
