re: volume
This really tells you whether a stock movement is significant of not.
The quoted share price is the last sale. If there is a big rise or drop but only a few shares have changed hands it is less significant than if a large number of shares have changed hands at that price.
What tends to happen is that when a share starts moving day traders close in and "pump and dump" - push the sp up (with help from a large amount of ramping, esp on hotcopper), then sell while its up and hence drop the sp back down. They make their money from the suckers who buy near the peak (ie the ones the traders sell at a profit after buying at a lower price in the last few days).
This is responsible for the massive volumes you will see on a stock (eg WMT had a share turnover of almost 300 million in one day during a run despite having only 300 million shares as day-traders came in and out repeatedly.
This causes great volatility.
regarding WTN - I don't know. It doesn't have the results to go much higher and much of this is the latest U run sweeping it up, which will likely relax back soon and take WTN with it, unless good drill results are released in the meantime. Maybe a retrace back towards 42-45c would be on the cards.
