Glide Path

When an airplane sees the runway, there are red and green lights the pilot dials in. Green=good; red=you're dead. She flies (hopefully) between those two colored lights.

The same happens with companies that are heading toward some natural end. Maybe it's a financial work-off of their assets to stockpile cash for a final dividend distribution. Maybe it's bankruptcy. Maybe it's a sale to a competitor. But the glidepath they're on describes how quickly they are flying toward the runway, and at what kind of steep (or not steep) angle they're getting there.
