COVID-19 also affected the financial markets and crypto markets significantly, however, some crypto markets flourished and touched their peak during the pandemic era. This study performs an analysis of the impact of COVID-19 on public opinion and sentiments regarding the financial markets and crypto markets. It conducts sentiment analysis on tweets related to financial markets and crypto markets posted during COVID-19 peak days. Using sentiment analysis, it investigates the people\u2019s sentiments regarding investment in these markets during COVID-19. In addition, damage analysis in terms of market value is also carried out along with the worse time for financial and crypto markets. For analysis, the data is extracted from Twitter using the SNSscraper library. This study proposes a hybrid model called CNN-LSTM (convolutional neural network-long short-term memory model) for sentiment classification. CNN-LSTM outperforms with 0.89, and 0.92 F1 Scores for crypto and financial markets, respectively. Moreover, topic extraction from the tweets is also performed along with the sentiments related to each topic.<\/jats:p>","DOI":"10.1371\/journal.pone.0286541","type":"journal-article","created":{"date-parts":[[2023,9,28]],"date-time":"2023-09-28T17:35:29Z","timestamp":1695922529000},"page":"e0286541","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":12,"title":["Analyzing influence of COVID-19 on crypto &amp; financial markets and sentiment analysis using deep ensemble model"],"prefix":"10.1371","volume":"18","author":[{"given":"Patrick Bernard","family":"Washington","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-5965-6379","authenticated-orcid":true,"given":"Pradeep","family":"Gali","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Furqan","family":"Rustam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8271-6496","authenticated-orcid":true,"given":"Imran","family":"Ashraf","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,9,28]]},"reference":[{"issue":"15","key":"pone.0286541.ref001","doi-asserted-by":"crossref","first-page":"8578","DOI":"10.3390\/su13158578","article-title":"Covid-19 pandemic: Is the crypto market a safe haven? the impact of the first wave","volume":"13","author":"D Vukovic","year":"2021","journal-title":"Sustainability"},{"key":"pone.0286541.ref002","doi-asserted-by":"crossref","first-page":"101954","DOI":"10.1016\/j.frl.2021.101954","article-title":"Who raised from the abyss?
