The close was bull.
Have a look at the following:
1. Price immediately before close was 5.61 - this was the lowest it had traded all day.
2. Closing price auction - price at 5.45 - 16 cents lower - it had not traded anywhere near there all day
3. A close at 5.61 = 3.61% drop
4. A close at 5.45 = 6.36% drop
Ridiculous.
