investors could care less about the merger. This company is tied to the oil price unless we get a major return above the market adv. Theoretically, if superior comes online we should see a bump in the stock price, however that assumption is likely already priced in with long term investors.
Moreover the biggest issue with CVE is that it has a majority owner (if you say otherwise you are fooling yourself IMO) and when that happens most investors stay clear of said company. As such CVE will likely be a stock lager compared with its peers and in a few years (provided the company still exists) there will be more talks about how 'undervalued' the company is. Or maybe I'm wrong and CVE will go to the moon!!!!
