Also, a viable treatment for pancreatic cancer is what got me interested in investing in this company in the first place. Even a treatment that can contribute to a cure, such as when used in combination with chemo to shrink tumours to the point where a significant number of patients that were previous deemed inoperable can then be reclassified and have surgical resections of their pancreas to remove the section of the pancreas that contains the tumour (the only known current cure for pancreatic cancer being a surgical resection). It was a good news story as far as I was concerned. However, I wasn't donating to a charity. I was investing in a company to hopefully make a profit. I was very confident that they'd get their CE Mark based on what they announced to the market (what they were telling us). It was a good-news company I thought. They're doing good, and we can make a lot of money when they commercialise the procedure. Trouble was - I was believing everything the company told me. The CE Mark was imminent. They had satisfied all the criteria. They had supplied everything required and more. Apparently not, as it turns out. Blind faith is OK as the basis of a religious belief, but not a good basis for investments. Neither is hope. Based on the facts presented this week, if you didn't have any money invested in OSL already, would you seriously consider investing in them now? That is often a good question to ask yourself when you're thinking about whether to sit tight, buy more, or bail out. We all have natural biases. However, the best investors learn to recognise and ignore their own emotions and biases. Investing is about the brain, not the heart.
