Yep ... I'd be buying with my ears pinned back if it fell to $17 ..... not saying it's likely, just that it's a possibility, say 18mths down the track if we get a prolonged downturn.
Could fall to the low $30's where I would be dipping the toe in ... if $30 fails then around $27.50 is where I would be placing a major buy order.
All hypothetical based on the inexact "science" of charting ... but "ya neva really know"
