New Issue Swaps?

Can someone explain how “new issue swaps” is related to Secondary Trading Rationales? I’m having a difficult time finding the context of the rationale?? Is it that for new issues, there is a better gauge for the credit spreads, which gives more confidence in secondary trades?? Thanks,

New issues are more liquid so people swap out their old issues for new issues.

thanks… Just wanted to confirm they werent talking about “swaps” in the ss13 sense.

F… you gave me heart attack - I had just finished the reading on swap yesterday and was wondering what the heck is he talking about? Did I forget again :frowning:
