Never try to catch a falling knife

Let this be a lesson for millions of investors out there, never buy a falling knife. Always wait for a turnaround and even then keep a stop loss. We are seeing in the case of PAYTM that the stock kept falling and there was no hope. However retailers kept on buying thinking that how low can this go?

Lesson: never buy a falling knife without a turnaround and then also always have a stop loss.
