More like a race to the bottom. If everyone else is e.g. using Bahamian tax shelters, and your company explicitly states that it won't do that, then your company's stock price will go down, because the market predicts that without those "table stakes", your company is not going to be competitive with all the companies who are willing to do that. (Whether that's true or not is irrelevant; it's only about whether the market believes it's true.)
