Origin Energy has had a rough year, with its stock tumbling 46 per cent since January in line with the falling oil price, but analysts are optimistic its latest strategic moves mean the worst is behind it.

It entered a trading halt last week from which to reveal a $2.5 billion capital raising and $2.2 billion in cost savings. After raising just shy of the $1.4 billion it expected to reap from fund managers, Origin shares fell at the resumption of trading on Tuesday, although they traded well above the "equivalent price" that takes into account the issue of new shares.
