With the biggest Hong Kong protest in recent history taking place over the weekend, and continuing indefinitely because one thing is certain: the local student demands for more democracy and the ouster of HK chief executive CY Leung will not be met, what everyone has focused on is what China's response, call it crackdown, to the breakout of violence will be. After all, while algos and the Fed's liquidity tsunami have priced in pretty much everything short of (or including, according to some) World War III, a repeat of Tiananmen square could well be large enough to where it registers as a slight downtick in the Fed's balance sheet, pardon the S&P 500.
