SH, can you imagine what would've happened...
if Lehman issued a PR indicating they intended to buy 1.9 million shares of Afren. Think about if they would've issued the PR after they had bought 5% and were still buying. The price would've went up in a hurry. You can bet their buying is finished now though! It was done with controlled buying and patience.
Also, if they bought damn near a 10% stake of a company with a 4.5% stake in block one, what do you think they or other companies are thinking about a company with a 22% stake in block 2?
Are we seeing controlled buying and not even noticing it?
