Shanghai stocks to open lower but there's an interesting seasonal pattern

The Shanghai Composite falls on Thanksgiving but rebounds on Cyber Monday

The Shanghai Composite dumped more than 2% on Thursday then finished flat on Friday. Today it's poised to open 0.2% lower but that dip is worth buying if history is any guide.

The WSJ notes that over the past decade the index usually falls substantially on US Thanksgiving and Black Friday, only to rebound the following Monday.
