The S&P 500 hit a new high last week and the Dow Industrials followed suit with a new high this week. Overall, the Dow broke triangle resistance with a surge on Thursday and this breakout signals a continuation of the current uptrend. Broken resistance turns first support to watch. A strong breakout should hold and a quick move back below 18000 would show cold feet. The March-April lows mark key support in the 17600 area. The triangle is around 700 points high (18300 to 17600).
