It can be the reflection of a complexity in the return generation process that had been formerly ignored, and thus represent a real advance in empirical asset pricing. Or the need to increase the number of factors could just represent an admission of weakness in the quest for parsimony in factor models, because the right way to unfold the universe of systematic risk exposures has not been found. If the latter explanation prevails, then researchers should keep on attempting to improve factor construction methodologies in order to show that the supplementary risk premiums become useless when the original ones are properly determined. Before moving to five-, six- or seven-factor models, one should first do whatever possible to reject all possible explanations of deficiencies of the original three-factor asset pricing model. This is the major objective of our paper, and we believe that it contributes to reinforcing a parsimonious approach to asset pricing.<\/p>\n<p>\n\tThe independent sorting procedure pertaining to the Fama and French factor construction method could provide a realistic explanation for these apparent pollution effects, but this conjecture needs to be rigorously scrutinized. This scrutiny has not formed the primary focus of the aforementioned studies. Our main arguments rely on the fact that the Fama and French sorting methodology leads to an inconsistent definition of value stocks: in their framework, value stocks are tilted towards micro-capitalizations. Our paper revisits the way in which size and book-tomarket effects translate onto risk factors: We show that the Fama and French premiums are contaminated by cross-effects that are not adequately neutralized by their independent sorting procedure. To achieve this objective, we follow the sequential methodology proposed by Lambert and H&uuml;bner (2013), used to isolate fundamental risks into portfolio returns. By removing contamination effects in the way to construct empirical risk premiums, we aim to shed new light on the relative importance of the size and book-to-market effects in the US market over an extended period (1963-2014). We demonstrate the existence of a strong value effect, whereas not in the way Fama and French measure it1. We differentiate ourselves from the cited literature challenging the existence of size and value effects by controlling ex ante for external factors rather than a posteriori.&quot;<\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\" id=\"block-854363cc-8450-4dc0-a06a-c737766e9431\"><strong>Are you looking for more strategies to read about? <a href=\"https:\/\/\\\/\\\/new-fmhwbzh6ghd9hede.swedencentral-01.azurewebsites.net\/sign-up-for-our-newsletter\/\">Sign up for our newsletter<\/a> or visit our <a href=\"https:\/\/\\\/\\\/new-fmhwbzh6ghd9hede.swedencentral-01.azurewebsites.net\/blog\/\">Blog<\/a> or <a href=\"http:\/\/\\\/\\\/new-fmhwbzh6ghd9hede.swedencentral-01.azurewebsites.net\/Screener\">Screener<\/a><\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" id=\"block-65925002-6290-4d3b-b5cd-f3a277851ec8\"><strong>Do you want to learn more about Quantpedia Premium service?

We demonstrate inconsistent pricing of those factors in the US stock market. We replace Fama and French&rsquo;s independent rankings with the conditional ones introduced by Lambert and H&uuml;bner (2013). Controlling ex-ante for noise in the estimation procedure, we have been able to highlight a much stronger book-to-market and size effects than have conventionally been documented similar to Asness et al. (2015). As a significant related outcome, the alternative risk factors have been found to deliver less specification errors when used to price investment portfolios.<\/font><\/p>\n<p>\n\tNotable quotations from the academic research paper:<\/p>\n<p>\n\t&#8230;<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-623","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/vvv.quantpedia.com\/es\/wp-json\/wp\/v2\/posts\/623","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vvv.quantpedia.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vvv.quantpedia.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vvv.quantpedia.com\/es\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/vvv.quantpedia.com\/es\/wp-json\/wp\/v2\/comments?post=623"}],"version-history":[{"count":0,"href":"https:\/\/vvv.quantpedia.com\/es\/wp-json\/wp\/v2\/posts\/623\/revisions"}],"wp:attachment":[{"href":"https:\/\/vvv.quantpedia.com\/es\/wp-json\/wp\/v2\/media?parent=623"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vvv.quantpedia.com\/es\/wp-json\/wp\/v2\/categories?post=623"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vvv.quantpedia.com\/es\/wp-json\/wp\/v2\/tags?post=623"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
