To understand the financial markets, you need to understand the hierarchy of asset classes.
That hierarchy is as follows:
Globally, the stock market is about $69 trillion in size, trading about $191 billion in shares per day.
The bond markets are well north of $140 trillion, and trade about $700 billion in volume per day,
The bond market is the SMART money and reacts to major policy changes before stocks.
On that note, the bond market has realized QE is ending in Europe and Japan.
On that note, in July the bond markets signaled that something BIG is coming to the markets. The yields on 10-Year Treasuries, 10-Year JGBs and 10-Year Bunds rocketed higher.
