whats with this share price drop?

I don't hold any TSE at present but have held in the past and as it always treated me well, I always keep an eye on it.

I am perplexed at the current share price drop. It has gone from 4.20 to 3.20 in the past 6 weeks and the announcements I read are only about winning more contracts.

TSE have always had an average public liaison capability (imo) and I am left wondering what is going on with this company at the moment.

I dare say I will be buying again soon as I think they are a great service provider but can anyone point out why the current drop?

Is it just end of financial year cleansing of the books?
