We find that factor returns di er substantially depending on when the data were downloaded, and only a small portion of these retroactive changes is explained by revisions in the underlying data. We show that factor changes have large effects in two widely-studied contexts: cross-sectional equity pricing and mutual funds. Model evaluation tests suggest that more recent vintages do not perform better. Our findings have significant implications for the replicability and robustness of finance research.<\/p>\n<\/div><\/section>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":47,"featured_media":7253,"parent":0,"menu_order":0,"comment_status":"open","ping_status":"closed","template":"","format":"standard","meta":{"featured_image_focal_point":[],"show_featured_caption":false,"ulux_newsletter_groups":"","uluxPostTitle":"","uluxPrePostTitle":"","_trash_the_other_posts":false,"_price":"","_stock":"","_tribe_ticket_header":"","_tribe_default_ticket_provider":"","_tribe_ticket_capacity":"0","_ticket_start_date":"","_ticket_end_date":"","_tribe_ticket_show_description":"","_tribe_ticket_show_not_going":false,"_tribe_ticket_use_global_stock":"","_tribe_ticket_global_stock_level":"","_global_stock_mode":"","_global_stock_cap":"","_tribe_rsvp_for_event":"","_tribe_ticket_going_count":"","_tribe_ticket_not_going_count":"","_tribe_tickets_list":"[]","_tribe_ticket_has_attendee_info_fields":false,"event_start_date":"2022-06-30 12:00:00","event_end_date":"2022-06-30 13:15:00","event_speaker_name":"Professor Pat Akey","event_speaker_link":"","event_is_online":false,"event_location":"Main Building, Room D10D\/D10E ","event_street":"成人头条 6 Rue Richard Coudenhove-Kalergi","event_location_link":"","event_zip_code":"1359","event_city":"Luxembourg","event_country":"LU"},"events-topic":[301],"events-type":[],"organisation":[116],"authorship":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.3 (Yoast SEO v22.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>DF Lunch Seminar Professor Pat Akey, 成人头条versity of Toronto - FDEF events I 成人头条.lu<\/title>\n<meta name=\"description\" content=\"Abstract: The Fama-French factors are ubiquitous in empirical finance.
