Having a look at the Top 20 shareholders it seems that not much action has been taking place there since out of the top 20 only one has increased the position by 72k shares which isn't much in the scheme of things... Institutional investors have already invested with the SPP and holding, the low volume trades with the SP going lower since the EPA approval post 25 November until recently have IMHO been retail investors either taking profits or reallocating capital. I know in late March that a couple financial planners have been putting sophisticated/wholesale investors into the stock (with one planner having clients put in over a million dollars) so my "thoughts" are that the increased volume lately is likely coming from there and potentially some passive ETFs with the addition to the ASX 300... Just my humble opinion - DYOR
