    • Abstract:
      This article analyzes models for forming an optimal investment portfolio, specifically Markowitz's optimal portfolio theory and the CAPM (Capital Asset Pricing Model). In the analysis section, a portfolio was constructed and examined based on data from 15 joint-stock companies operating in Uzbekistan, using stock price data from the last five years. Additionally, insights from various economists such as William Sharpe, Kan, and Zhou are presented. The beta coefficient between the UCI market index and the expected return of the portfolio was calculated, and the expected return of the portfolio, as well as the efficient frontier, was determined using CAPM. The article concludes with general findings and recommendations. ; Ushbu maqolada optimal investitsion portfelni shakllantirish modellari, xususan Markovitsning optimal portfel nazariyasi va CAPM (kapital aktivlarini baholash modeli) kabi modellar tahlil qilingan. Tahlil qismida esa Oʻzbekistonda faoliyat yuritayotgan 15 ta aksiyadorlik jamiyatlaridan olingan maʼlumotlar oxirgi 5 yillik aksiyalar narxlari maʼlumotlari asosida portfel tuzilib, mushohada qilingan. Shuningdek, turli xil iqtisodchi olimlar Uilyam Sharp, Kan va Zhou kabi olimlarning fikrlari keltirilgan. UCI bozor indeksi va portfeldan kutilayotgan qaytim oʻrtasidagi beta koeffitsiyenti hisoblangan, portfeldan kutilayotgan qaytim CAPM va samarali portfel chegarasi aniqlangan. Maqola soʻngida umumiy xulosa va takliflar berilgan. ; В данной статье анализируются модели формирования оптимального инвестиционного портфеля, в частности теория оптимального портфеля Марковица и модель оценки капитальных активов (CAPM). В разделе анализа был составлен и рассмотрен портфель на основе данных 15 акционерных обществ, работающих в Узбекистане, с использованием данных о ценах акций за последние пять лет. Кроме того, приведены мнения различных экономистов, таких как Уильям Шарп, Кан и Чжоу. Рассчитан бета-коэффициент между рыночным индексом UCI и ожидаемой доходностью портфеля, а также определены ожидаемая доходность ...
