Interesting,
On HC, "Price Chart" for Key shows a spike to around 49.6c on about the 12th March but I cannot recall this happening.
My CommSec Chart shows only 11c low and high on this day.
Am I reading something wrong? What does your chart say?
This is bizarre..... happened to me the other day on HC (can't remember which stock, but my chart for that stock was definitely different to other posters' charts).
