Often, they will use 100 share trades to take a pps up or down, depending on what their desire is. If they have shares they want to sell, they will try to 'take it up', giving the appearance of a pps going up in value. Conversely, when they need shares, they 'take the pps down', on 100 share trades, hoping to 'shake weak hands' loose of their shares with the fear of a plummeting pps.
