I called TD when all of the people saying it was impossible came out to share their opinions. I was told that it was very rare for that to happen. The broker told me that it would only happen if there was a merger and new financials drastically changed the company profile. That sounds like what RPH and BS is promising, so I think it could happen. I am very skeptical and sold the majority of my shares today to buy IDWD. I may sell IDWD mid day tomorrow and get back into CSHD for around 1.10.
