In this paper, we crawl stock comments from China\u2019s most popular online stock forum, East Money (www.eastmoney.com), and then develop a sentiment classifier using the LSTM method. Using the online investor sentiment of the stock forum, we explore the effect of online investor sentiment on the stock movements of CSI300. The results show that online investor sentiment has a significant positive impact on both stock return and trading volume and remains significant after controlling book-to-market ratio, BETA, and market value. Moreover, investor sentiment has a significant positive impact on order imbalance of big trade, which represents the main flow of money in the market. As a result, investor sentiment has a positive impact on the major fund flows in the market. In other words, an increase in investor sentiment can boost the major money flows in the market to some extent. From a practical point of view, investor sentiment can assist investors to make investment decisions and help the government to regulate the stock market.<\/jats:p>","DOI":"10.1155\/2020\/4754025","type":"journal-article","created":{"date-parts":[[2020,12,3]],"date-time":"2020-12-03T14:20:15Z","timestamp":1607005215000},"page":"1-11","source":"Crossref","is-referenced-by-count":22,"title":["The Effect of Online Investor Sentiment on Stock Movements: An LSTM Approach"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5140-8378","authenticated-orcid":true,"given":"Gaoshan","family":"Wang","sequence":"first","affiliation":[{"name":"School of Management Science and Engineering, Shandong University of Finance and Economics, Jinan 250014, China"},{"name":"Institute of Digital Economy, Shandong University of Finance and Economics, Jinan 250014, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6508-774X","authenticated-orcid":true,"given":"Guangjin","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Management Science and Engineering, Shandong University of Finance and Economics, Jinan 250014, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7048-9751","authenticated-orcid":true,"given":"Xiaohong","family":"Shen","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Shandong University of Finance and Economics, Jinan 250014, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1007\/s11042-016-3643-4"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2018.02.095"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1057\/s41265-016-0034-2"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1155\/2017\/2407086"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1111\/deci.12229"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbankfin.2017.07.002"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2016.12.036"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijforecast.2019.05.010"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1080\/00036846.2015.1109048"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1016\/j.jebo.2014.04.015"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1080\/16081625.2017.1311797"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.2753\/ree1540-496x5002s210"},{"key":"13","article-title":"Risky short positions and investor sentiment: evidence from the weekend effect in futures markets","volume":"22","author":"V.
