The news media have been abuzz for a few weeks about the proliferation and effect of fake news. Facebook Inc. is changing how it handles news from dubious sources, while Twitter Inc. is rethinking how to respond to bots promoting fabricated articles. Alphabet Inc. (Google) has rejiggered its algorithms to fight phony stories.
All of which raises some very interesting questions for investors and traders. It's worth remembering that financial markets have been dealing with hoaxes, frauds and fake news for a long time. The wrong response can be costly.
