Sell RIV? At the right price of course, but not at $17. RIO is my stop loss. With the right counter party this share may go to $20+. The large XT trades today indicate someone substantial is buying and will be outed soon. No-one buys 1,000,000 shares @ $17 with RIO's $16 offer on the table unless they are are a potential bidder themselves or strengthening their position ahead of a counter offer. My guess is the indian's were buying today.
