Technical Summary: The long term chart of BHP reflects the fundamental volatility of the resources sector. With the stock pulling back from around $35 per share and bottoming close to $13 at the beginning of 2016. The stock has since staged a oversold rally. This rally found resistance at around $28 per share at the beginning of 2017 as the stock fell back to a low of just above $22 per share. Since that time the stock has made a series of higher lows and is trading around the $28 level which was its previous top. This is a difficult chart to interpret but the stock appears to be holding its 50 day moving average in an uptrend while experiencing resistance at previous highs. This is difficult to trade from a technical point of view and may be best left to the fundamental analysts.
