It includes decisions on whether to keep on investing or to exit from a market subject to huge price swings, and also how to price in news or rumors attributed to a specific stock. The question then arises how professional traders, who specialize in daily buying and selling large amounts of a given stock, know how to properly price a given stock on a given day. Here we introduce the idea that people use heuristics, or \u201crules of thumb\u201d, in terms of \u201cyard sticks\u201d from the performance of the other stocks in a stock index. The under or over performance with respect to such a yard stick then signifies a general negative or positive sentiment of the market participants towards a given stock. Using empirical data of the Dow Jones Industrial Average, stocks are shown to have daily performances with a clear tendency to cluster around the measures introduced by the yard sticks. We illustrate how sentiments, most likely due to insider information, can influence the performance of a given stock over period of months, and in one case years.<\/jats:p>","DOI":"10.3233\/af-2011-013","type":"journal-article","created":{"date-parts":[[2019,11,9]],"date-time":"2019-11-09T17:43:52Z","timestamp":1573321432000},"page":"183-190","source":"Crossref","is-referenced-by-count":6,"title":["Pricing stocks with yardsticks and sentiments"],"prefix":"10.1177","volume":"1","author":[{"given":"Sebast\u00edan Mart\u00ednez","family":"Bustos","sequence":"first","affiliation":[{"name":"Department of Mathematics, Unversidad de los Andes, Bogot\u00e1, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00f8rgen Vitting","family":"Andersen","sequence":"additional","affiliation":[{"name":"CNRS, Institut Non Lin\u00e9aire de Nice, Sophia Antipolis, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michel","family":"Miniconi","sequence":"additional","affiliation":[{"name":"Laboratoire J.-A.
