Teck knows more about CUU, knows how much its worth (they are privy to BFS) . Also I doubt any company is going to read Vettes blog and learn anything about CUU or sees the SP go up and is thinking "damn we better bid on CUU" Really! Long on CUU. not a basher.
You're missing the point. It's causing pressure by the exposure being brought on. New investors bring life in. If an institution, or fund for example decides to invest in CUU, and does so because the company has been brought to their attention than the SP will move up. That's just simple demand > supply.
Currently our SP is controlled by traders. When our SP moves up, traders will still have an effect, but probably in an upward direction as more traders try to trade because of technical indicators (momentum, higher lows, higher highs etc, patterns etc.) All of this relies on more demand, and more liquidity.
Some people do know people in high places. Not everyone does know about CUU, or knows enough about it. http://www.miningfeeds.com/copper-mining-report-all-countries
That's a list of the copper stocks around. Knowing about everyone, and knowing in depth about eachone is just impractical, even for big companies. Having a starting place to do research is a huge help.
Now, let's go with the thinking and assume that our SP does go up, and TECK makes an offer, if it's a 300% premium, not likely a bidding war. But if our price has rose a lot to begin with, and say they offer the exact same amount, but it's a 25% premium, other companies are MORE LIKELY to jump in. That's just psychological.
