A falling knife is a security which has a steep decline with virtually no counter move on the way down. Falling knife stocks have been a vice for a number of traders for a long time. There is something within a trader's nature that forces him to step in front of this freight train. The issue with buying a falling knife is that they are dropping like a rock for a reason. Stocks fall at an accelerated rate right before a bankruptcy or after a horrible earnings report. The odds of being able to pin point the exact bottom of a falling knife are slim to none.
Becoming a winning trader is about having patience. Catching a falling knife requires enormous patience and control of one's emotions. A classic method for buying a stock that is falling swiftly is to wait for climatic volume. A pickup in volume of 500% or more will often flush out the strongest of longs, thus leaving no one left to sell.
The summer months of 2008 have proved brutal for the financial markets. Below is the chart of Freddie Mac (FRE), which is a perfect example of a falling knife as it fell from $25 to under $4 in less than a month. Notice how the volume spike preceded a 100% reversal off the bottom.
