Well, this was just ugly. All three major indices traded in correction territory today or more than 10 percent below their 52-week highs. For the Nasdaq Composite, the 50 day moving average crossed the 200 day moving average, forming a pattern that goes by the catchy name “death cross”. The Nasdaq Biotechnology ETF closed down 6.3%, following a 5% drop on Friday.

Shares in mining and trading company Glencore fell almost 30 percent and closed at a record low, wiping out more than $5 billion in market valuation. The fall followed publication of a note by analysts at investment bank Investec which raised doubts about Glencore's valuation if spot metal prices do not improve. The note pointed to high debt levels and a need for deeper restructuring. The analysts wrote: “If major commodity prices remain at current levels, our analysis implies that, in the absence of substantial restructuring, nearly all the equity value of both Glencore and Anglo American could evaporate.” Glencore, a Swiss based company, has said it will suspend dividends, sell assets and raise cash with a $2.5 billion share placement, among other measures, to cut its $30 billion debt pile and protect its credit rating.

The 15-month commodities free-fall is starting to resemble a full-blown crisis. A Bloomberg index of commodity futures has fallen 50 percent since a 2011 high, and eight of the 10 worst performers in the Standard & Poor's 500 Index this year are commodities-related businesses.
