A note on the second plot – the percent change is plotted as week-over-week. Any point above the grey line (zero change) means an increase from the previous week. The most notable thing here is that every week, the change in short sales is always a little bigger than the change in total listings, resulting in the steady (almost linear) increase in the percent of total listing that are short sales (the green line).
