Re: What would happen if...
Exactly as Pascal says: they can't withdraw their money from Toshiba, they can only sell their shares. If they do that all at once, the share price will fall. That will mean:
- The board looks bad
- If the board wants to raise more money by creating some more shares and selling them, it will be harder.
- If the board wants to take over another company by issuing shares, they will have to issue more
However, from the point of view of the activist shareholders, the most important effect, and the reason it won't happen, is that they will lose a lot of money. Remember these investors don't care about truth, transparency, or justice - they just want to make money. (Tosh has a market cap of about $16B. 17% of that is ~ $3B, even a 1% fall in the share price is $30M !).
