OptionSource.com was developed by Schaeffer's Investment Research to help educate investors about options trading. A large part of the site is devoted to familiarizing novice investors with options investing. To that end, a five-lesson series introduces investors to options trading. In addition, the site covers basic and more complex options trading strategies. Research on options trading, daily options market commentary, and an options glossary are also available. Investors may also obtain the latest stock and options quotes at the site.
