{"title":"How Machine Learning Is Reshaping Portfolio Optimization","authors":"Aarav Parakh","doi":"10.36676/jams.v2.i3.80","DOIUrl":"https://doi.org/10.36676/jams.v2.i3.80","url":null,"abstract":"This paper examines the changing nature of portfolio optimization by analysing the comparison between traditional financial models (in general, based on Modern Portfolio Theory (MPT)) and machine learning (ML) in their portfolio analysis capabilities. Traditional portfolio optimization methodologies depend on historical averages, past relationships, and fixed assumptions about risk and return, which have been the base of all investment strategies for decades. Emerging fintech companies have since provided new adaptive and data-driven methodologies that allow portfolios to be more dynamic and potentially lead to better risk-adjusted returns. This paper assesses the advantages and disadvantages of each approach through a literature review, industry examples, and Excel-based simulations. It employs approaches to evaluate performance that incorporate conventional performance ratios that measure expected return, volatility, and/or Sharpe ratios. These also include employment of examples from allocated contributors like BlackRock, Wealthfront, and Two Sigma used in which indicate how ML has already influenced a change in investment management. Findings presented demonstrate how the traditional approaches are comprehensible and straightforward, while they might not be able to adapt to more rapidly changing or complicated environments. Whereas ML-based investment strategy brings about certain adaptive capabilities in backtesting, predictive large data sets, etc., they do raise complex issues of course around risks associated with overfitting, explainability, and regulatory risk. Ultimately, the comparison illustrates that hybrid solutions that include aspects of financial theory and technology within the discourse will be required to pave the way to the future of portfolio construction in a more data-driven space.","PeriodicalId":6975,"journal":{"name":"Academy of Management Journal","volume":"2 3","pages":"93-119"},"PeriodicalIF":0.0,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147920733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
