A tweet that claimed President Barack Obama had been injured in an explosion caused the Dow Jones industrial average to fall and brought focus to the unreliability of information posted on social networking platforms.

Instead, traders should rely on creditable news sources because not only is Twitter open to anyone, but even reliable sources on Twitter can be hacked and misinformation can be spread quickly.
