<p>In this paper, an explicit solution to a continuous-time mean-variance portfolio selection problem in a continuous semimartingale model is provided through the Lagrange multiplier method and results of a mean-variance hedging problem. Without reformulation of the problem which is usually employed in the literature, we get a more straightforward method of solution than earlier studies.</p>
