The index closed above its previous 2,400 resistance twice in a row, in what could be construed as a positive, breakout formation. However, and as I said in an earlier post (see below), this took place in low volume and therefore requires confirmation. US market futures are looking down today. Should the market slide below 2,400 today (which looks likely), this would endanger the breakout. Further danger if the drop takes place in above-average volume, and/or if the market closes below this level.
