Generally when large parcels are traded the price does not match market price.
A recent example was FMG where a large stake was sold at a 10% discount to market.
Likewise, when buying a large 10% stake, a premium must be paid to be able to procure all those shares and that premium in this case was around 15%. This is also why in a takeover the premium paid is around 40%. This premium benefits the large funds that had holdings in VBA and not individual shareholders.
Nothing to see here folks, move along.
