Every year Macy's sponsors the massive Thanksgiving Day parade. If you look at the last several years, Macy's likes to increase its share price around November/December.
Now let's not forget that single individual that hid over 100 million dollars. Macy's pushed their earnings date back because of that. They just can't wait to share how many tendies they've been cooking after they give us a great parade
TLDR; Macy's Thanksgiving Day Parade make $M pop off before their new 12/11 earnings date
