Hello, I'm Geardona. I noticed that you added or changed content in an article, Portfolio optimization, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Geardona (talk) 15:07, 28 December 2023 (UTC)
