after the vote

If the consolidation is voted in (most likely outcome I reckon), the shareprice could see new pressure for a time, while it faces the $1.00 barrier.

The reason charting can be predictable (sometimes!) is because the market participants have a memory of certain price points that can work in favour or against.
There is nothing to suggest that the consolidation to approx. $1.00 will work in MPO's favour (talking simply pricewise). Without accompanying good news on their activities, there won't be much to support the 'jump in price' from 20c to $1.00- even though we know it is still worth the same as before?

If consolidation does not go ahead though, it might be worse. Will the larger shareholders be pee'd off, or, will the beneficial reasons sought by MPO for the consolidation, then be jeopardised?
More pressure on the price following a 'NO' decision is also possible.

Obviously MPO sees this consolidation as being in the best interests of the company, and therefore, all long term MPO shareholders, so should it no go ahead, there will likely be far worse ramifications in the long term than the short term pain felt by the consolidation.

Long term holders may ride this out in the long run. Short term traders or those wishing to capitalise on the uncertainty, regardless of their long term aspirations, may be the winners no matter which way the vote goes.
