This is the errata for Level 3.
However, I thought long put ALSO increases duration?
A long put decreases duration and increases convexity. Think of a put option as selling-a-bond-lite.
I was the one who pointed out the errors in the table. Rather than correct them, CFA Institute decided simply to remove them.
Sigh.
Ohh… that is right, thank you. A previous post of mine was removed here on analystforum.
Put increases convexity, not duration… thanks a lot! Yea they removed it, so, what, we don’t need to know anything about convexity now? Anyway… errata has a lot, a lot of pointed out mistakes.
