Macaulay Duration (SOA Exam FM - Financial Mathematics - Module 4, Section 3, Part 1)

I really appreciate the time you put into setting up this lesson. I have a much clearer idea of what MacD is, more than just the definition.

Glad it was helpful!

MacD made no sense before. It makes better sense now. Thank you professor!

You are the absolute best Sir. Stephen Paris

The way you derived the formula is absolute skillful, knowledgeable and student friendly. 🙏

Conceptual question here (I'm teaching this stuff, fun!) Generally speaking, "Duration" refers to the sensitivity of prices to rates (fixed rates or corresponding to spot rates). I understand the interpretation of MacD as a weighted average (as analogous to the expected value in probability), but how does this fit in with the overall practical idea of Duration via above!? Hell, I'm reading in Broverman's book that Macaulay himself didn't think to use the MacD formula to measure sensitivity of prices to rates! I'm inclined to basically teach Modified Duration as "the" duration definition, and then almost teach MacD as itself a "modified duration". Thoughts?
