Portfolio optimization involves constructing a portfolio that maximizes returns while minimizing risk. The novelty in methodology is ‘hybridizing’ nature-inspired algorithms for optimized portfolio selection with two independent modules: intrinsic value of stocks and financial health analysis. This integrated approach aids decision-making by considering multiple dimensions of stock performance. Custom datasets are designed for each input module using historical fundamental data. The DSS output presents an optimized portfolio. Comparison for different risk profiles shows that as risk increases, returns of optimized portfolios decrease from 55 % to 24 %. Results for keeping other inputs the same for varying cardinality show that as cardinality increases, returns decrease. The results show that fundamentally undervalued portfolios outperform growth portfolios by a considerable margin. We conclude that optimized portfolios with varying constraints, >80 % of the time, outperform US market indices.</div><div>Key contributions include:<ul><li><span>•</span><span><div>Developed a decision support system using intrinsic value and financial health analysis.</div></span></li><li><span>•</span><span><div>Novel fitness function for optimization using hill climbing and SHLO.</div></span></li><li><span>•</span><span><div>Integrated module outputs with hill climbing and SHLO for portfolio optimization.</div></span></li></ul></div></div>","PeriodicalId":18446,"journal":{"name":"MethodsX","volume":"14 ","pages":"Article 103413"},"PeriodicalIF":1.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144280863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that self-esteem would mediate the connection between social competence and resilience. Participants were assessed using standardized measures of self-esteem, social competence, and resilience. The results indicated significant positive correlations among all three variables.

Social competence had both direct and indirect effects on resilience through its influence on self-esteem.

In response, antibiotic stewardship programs (ASPs) have been widely endorsed as a core strategy to promote the responsible use of antimicrobials and to curb the progression of antimicrobial resistance (AMR).

However, despite their potential, the current body of evidence evaluating the effectiveness of pharmacist-led audit and feedback within ASPs remains limited and fragmented.
