Abstract
Yatırım ile ilgili kararlar verilirken kişiler hem kendi tecrübelerini yansıtacakları hem de bilimsel gerçekleri kullanabilecekleri yöntemler ararlar. Kullanılacak yöntemin kolaylığı ve hızlı sonuç vermesi yöntemde aradıkları ilk şart olmaktadır. Tecrübelerini yansıtabildikleri ve bilimsel bir yöntem olan Promethee sıralama yöntemi çoğu yatırımcı için uygun bir yöntemdir. Bu çalışmada portföy oluştururken tercih edilecek olan hisse senetlerinin seçiminde çok kriterli karar verme tekniği olan Promethee kullanılması amaçlanmıştır. Yöntem seçilirken Promethee’nin finansal kararların alınmasında kullanılabilirliği ve yöntemin uygulanmasının kolaylığı göz önünde bulundurulmuştur. Uygulamaya 2016 yılının ilk iki çeyreğinde BIST-100 endeksinde yer alan şirketler dahil edilmiş ve 2010-2015 yılları arasındaki verileri incelenmiştir. İşlem miktarı, işlem hacmi ve volatilite kriterleri açısından portföye dahil edilmesi gereken hisse senetleri tespit edilmiş, Promethee sıralama yönteminin portföy oluşturmada yararlı bir araç olduğu belirtilmiştir. \n \n-------------------- \nInvestors seek methods in which they can reflect their own experiences and use scientific realities in decision making process.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
