RE:RE:SPHi atika, I should have checked on the sedi website before posting, which I did later on.
There is indeed one Mathas Thibieroz who has been selling heavily (more than 1M shares) in the last few weeks, the same Thibieroz who was involved in the building of Robex infrastructure as general contractor, if my memory serves me well.
Let's hope that this gentleman is bought out soon so that SP resume its upward trend.
