RE:Major down-trend lines broken...We are also butting up against the 50 day MA. Which is positive in that Maxar hasn't seen its 50 day moving average much in the past year or so (this is the second time, previous time failed). The 50 day MA would need to fall in order for share price to advance.
This stock has the makings of a stock that could increase but it needs and/or is looking for a significant catalyst. Q1 could be that catalyst (whether bullish or bearish).
In the meantime, we could linger here in the absence of any new developments although Q1 results should be out next week.
