It appears today's weakness in stocks (most notably high-beta momo) and bonds (HY credit weakness) was triggered by two "ma"s - grandma Yellen and grand-poohbah BABA's Ma. Hawkish FOMC concerns took the shine off HY credit (and stocks) but Treasury bonds rallied modestly (5Y -3bps, 10Y -2bps). However, high-beta momo stocks dragged Nasdaq and Russell lower as 'smart money' proclaimed this was making room for the Alibaba IPO (which raises the question - if there is so much pent-up demand money on the sidelines just dying to be lost in the stock market, then why were so many high-beta, high-growth, momo names being sold today, theoretically in order to make room for the BABA IPO?) The USDollar ended marginally higher (GBP weakness, EUR strength) but most commodities gained on the day (Copper down on China) with WTI back to $93. Stocks did have a mini-melt-up on absolutely no news whatsoever into the last hour but gave most back. The Russell 2000 is -0.5% in 2014.
