In the absence of any conflicting facts to the contrary a neutral position in this instance is sensible and logical.

Of course, the self-interest of others usually dictates that it would have been preferable had the sale of shares from such a high profile holder not occurred and there will be many hypothesis's put forward as to other possible available "options" if it was a question of "needing the money".

The current facts are that he has sold some of his holdings. The deal is done, dusted and disclosed.

Neutral is a good position to take. On the premise, of course, that the right to change an opinion (position) based upon other facts which may not yet be apparent but which may subsequently be revealed is always reserved.
