SG - first sorry to hear about your Dad. Such a shame, especially when we know PVCT could have saved his life, only a matter of time. My brother and 2 sisters-in-law have had numerous bouts of melanoma, and one has breast cancer that has metastasized to 5 major organs.
One way to look at this and any investment, and that works for me, is to look at each day or week as a brand new investment day. Look at your holdings, see if the reason you bought still stands. If not, and there is some material event that would fail the 'do I buy today?' question, then don't. If things have changed for the positive, look at holding or even adding more.
My reasoning, for PVCT at least, is I am convinced the tech works, based on my early conversations and trust level of the company. So then it is a matter of timing. But that's me and each of us is different, and have different comfort levels. I am at the point personally that I wish I had more to invest at these levels. Everything that was anticipated is falling into place at light speed recently.
Hope this helps.
