As the phrase suggests, buying into a market with a lot of downward momentum can be quite dangerous.

This term implies that the investment will never be a good one again. Examples of stocks that have plummeted are plentiful; a widely-held stock can drop precipitously as the equity ownership is reduced to nothing.
