Bionic Turtle’s Week in Risk (ending October 14th)

Welcome to our Week in Risk blog! This week, we wrapped up our Hull, Chapter 19 reading with 6 new practice questions. Our newest YouTube video asks the question, “Is it optimal to early exercise an option?”. Our forum has been VERY busy! There are some really great FRM forum discussions that you will want to take a look at before the exam. We hope you have a great week!
