I bought a small parcel recently in SNT but the iceberg seller at 30c puts me off, and besides, I have been attempting to trade CHM but I always seem to end up on the wrong side of a trade. Holding CHM doesn't phase me because the pipeline and fundamentals are so good. I'm starting to get the impression that the SP is being suppressed here to soak up the stale holders and to increase position sizes now (rather than later) to negate the upcoming dilution in a roundabout way.
