Signs Of Woe For US Stocks

 | Aug 20, 2015 09:04

The S&P 500 is testing key 200-day support on Wednesday after slipping to the bottom of its range on the back of a global bout of risk aversion triggered by further declines in the Chinese stock market. However, we have started to notice a few ominous signs closer to home that could make the rest of Q3 and Q4 more difficult terrain for stock investors to navigate.

We think that investors should be watching two charts right now, which could spell a more serious period of unrest for US stocks.

h3 1) US high yield corporate debt/h3

High yield corporate debt is considered a bell weather for investor risk sentiment, so when it starts to show signs of stress, stock investors should take note. The chart below shows the Bloomberg high yield US corporate debt index and the Vix index, a measure of volatility in the S&P 500. This chart has been normalised, and as you can see, these two indices have generally traded in the same direction over the last year.

However, the high yield debt index has accelerated in recent weeks, as investors have charged more to hold the riskiest end of the US corporate debt market, it overtook the VIX in mid-July. The debt index is now at its highest level since December 2014, if this relationship is to hold then we could see further upside for the Vix. This is important for the S&P 500, since the Vix tends to have an inverse correlation with the S&P 500, thus if the Vix rises we may see the S&P 500 come under further downward pressure.
