Question regarding Synthetic Credit Strategies with CDS

Hi folks, me again.

I am so confused with an example on curriculum now.

On page 117 (Example 29) Volume 3 CFA III curriculum, the curriculum has the strategy to buy protection on the CDX IG Index and sell protection on the CDX HY Index. Ok fine.

But when it comes to the second question, where investment-grade credit spreads rise by 50% and high-yield credit spreads double (economic downturn), the buying of protection on CDX IG shows a loss due to its price depreciation.

My question is, since buying protection is shorting the risk and the widening spread should benefit the protection buyer, why it shows a loss ?

This one confused me too, but tell me if this makes sense
Solution to 1: The investor should buy protection on the CDX IG Index and sell protection on the CDX HY Index.
Solution to 2: …In this case, the investor takes the opposite position to that of Question 1, namely long CDX HY and short CDX IG

Look at errata. It is incorrect.

Thank you for your answer ! It seems this is erroneous as specified by 2022 CFA Program: Level III Errata - recommend that you could have a look at it too !

You saved me ! thank you, just had a look at 2022 CFA Program: Level III Errata and it was a seriously erroneous example question indeed.

Makes sense, I was wondering why they would change their position from Q1 to Q2
