PANIC BUYING: 

Aka FOMO (Fear of missing out) occurs when investors buy shares of a security because of a rapid price increase, in fear that if they don't get in they will miss out on a continued up move. This type of behavior ultimately leads to losses because the trade was executed without a proper plan, where no technical or fundamental evaluation was performed prior to jumping in. Many of my losses can be attributed to this behavior, and is a direct reflection of trading with your emotions. It is exciting to see a stock rip to the up side, but if it wasn't on your watchlist and you haven't analyzed the chart, stay the hell away from it. There will always always always always always always always always be another opportunity.
