Использование модели Блэка-Литтермана для построения эффективного портфеля ценных бумаг

Использование модели Блэка-Литтермана для построения эффективного портфеля ценных бумаг

Abstract

Модель Блэка-Литтермана позволяет инвестору учитывать свои прогнозы относительно доходности определенных активов при построении эффективного портфеля ценных бумаг на основе оптимизационной методики Г. Марковица. Статья сводит воедино результаты исследований авторов немногочисленных научных работ по модели Блэка-Литтермана и предлагает рекомендации по практическому использованию данной модели для построения оптимального, с учетом персональных прогнозов инвестора, портфеля ценных бумаг. Раскрывается смысл и предлагаются методики определения значений наиболее абстрактных параметров модели матрицы ковариаций стандартных ошибок прогнозов и масштабирующего множителя. Возможности и ограничения применения модели Блэка-Литтермана, а также методология расчета результирующего вектора удельных весов рассматриваются на числовом примере.
