After staging a powerful rally commencing the first week of December, this market is now showing signs of fatigue, with 4 consecutive Doji candlesticks over the past month. The last one is a Long Legged Doji, or Rickshaw Man, and suggests significant vulnerability at the end of an uptrend in any market. The 65 week moving average has also proven to be formidable resistance in recent weeks. A break below last week's low could bring on a swift correction back down to test the 78 support level, and 40 wma. Obviously such a move would have ramifications for many other markets, particularly currencies and commodities.
