Why do I see multiple trades of very small quantities?
It looks more like someone is trying to pocket the spread.  The trades are going off at the bid then the ask (from what I can tell without any L1 and L2 data, but the spread could be bigger than what the prices show, since the stock looks pretty volatile given the difference between current price and VWAP...).  Looking through the JSE rule books I didn't find any special provisions on how they handle odd lots in their Central Order Book, but the usual practice in other markets is to display only round lot orders. So these 4 share orders would remain hidden from book participants and could be set there to trigger executions from those who are probing for limit orders. Or to make a market with very limited risk.
