Ann: Change in substantial holding from WBC, page-5

There are a few days with substantial trades - 24 February - State street purchased just under 200,000 and on the same day BT Investment manager ( all companies) purchased approximately 434,000 shares. The 28th of February was another big day with around 160,000 being purchased.

I suspect that they only acquire on deep falls that a tightly held share can have when the market spooks. Great accumulation and in the entire process not one sale was recorded so it must represent a strong accumulation...

Would think they got a few more today...
