There are no guests in this week's show which is sponsored by Open Orphan PLC (ORPH). It is just me and I start with a phone cal from a young man urging me to buy a  cannabis stock. Then I look at why you are bound to lose money in junior mining and hydrocarbion plays. Finally I discuss the Golden Rule of Investing: Don't buy shares that are almost certain to go down. If you like this and can't wait seven days for more of the same and are tired of being a cheapskate you should listen to my Bearcast every day.
