And what have been the opportunity costs of being in PMCB for a long time? Answer: missed BIG gains in the market, as all indices have skyrocketed over the past several years.
People who have been long in PMCB have lost a lot so far in relation to the rest of the market. It MIGHT have made sense to cash in some profits made in the market over the past few years to take a flyer on PMCB at a nickel a share in October 2017. But being long in this stock has been a very unprofitable (losing) venture.
