SNG Charts TA, page-28

Sitting at about 0.5% of SNG, all acquired in the last 2 weeks average cost of $0.39. Original plan was to build a stake around 0.46 pre-release of drilling result announcement. Must admit I was not expecting the sustained selling pressure but cash is king according to Buffet & Munger. I will average my way in (opportunistic buy) all the way down and all the way back up again. Sounds like you are running a similar program. Can't imagine BR will want a low share price for when he returns to the market for more capital.
I agree with @jakedamuss, I think we are witnessing Morgans/others cashing their IPO fees. A few nervous/distressed retail investors bailing as well.
