Sales of anything tend to be tied directly to human action which is more or less seasonal. So it makes sense to compare to a comparable time the year before. I like millions of parents spent a few hundred dollars on backpacks, shoes, pencils and lunchboxes this week for back to school. Won't be doing that again until next year. The closest reset (when stores update their prices/products they carry) to November this very crappy wine I sometimes buy, goes from $6 a bottle to $3.89-- presumably to captures sales for holiday get togethers where people are looking for quantity and not quality. It stays at that 3.89 until after New Years. I don't know what the cycle is for housing-- but I suspect under normal circumstances sales would be highest about an escrow-long time before summer vacation so moving would be least impactful on kids.
