Xoma represents a couple of common themes in my investing, one positive, one negative, both a result of being a CLI.
The positive is that it is an example of playing with the house’s money, which is why I am hanging on to XOMA.
The negative is that Quicken, which I use for the (over-priced) convenience of synching multiple accounts, sucks at calculating profit and loss. Note in the feature image for this post how Quicken shows the total stock as 52.41% loss even though the original purchase was for $509.95 and then half those shares were sold for $572.05. As a CLI, I won’t bother re-calculating the actual gain, but it isn’t 0, let alone -52.41%.
