h0rc0 have you held this stock for long - perhaps you can help me with a couple of queries?

I am curious to know why this sudden drop?? I have three guesses;
1. people wait until pre-dividend payment to sell large numbers of shares as they know the price won't fall too dramatically with the dump.
2. the change in auditor could reflect a poor report from the previous auditor (hence the price drop and change)
3. the price is just fluctuating for no great reason and should return to normal soon

Anyone have ideas? I'm probably way off the mark.

Does this stock have a history of dropping heavily when it goes ex-dividend?? On the charts it doesnt seem to... I need to sell off for other reasons (will buy back in later) and dont know whether I should wait for the stock to go ex.
