Investopedia (https://www.investopedia.com/), founded in June 6, 1999 by Cory Wagner and Cory Janssen and headquartered in New York City, NY, provides investment dictionaries, advice, reviews, ratings and comparisons of financial products such as brokerage accounts. It has 17 million US unique monthly viewers.
Besides the financial news and info, it offers online courses for day trading, asset management, forex tradings and other financial educational courses.
Also, Investopedia runs a stock market simulator where the player is given a virtual portfolio and money to spend on the stock market.
In addition, it features latest news (company, markets, trading, political and trending) as well as personal finance information and advices.
I use this site to find out about financial dictionary and information. Pretty good site.
