A few days ago on TD, I saw wells fargo offering a 5 yr brokered CD with a coupon rate of 5.05%, with monthly interest, and the APY was ~5.169% as a primary offering.
That CD listing went away, but a few days later (still before issue date), I saw 5.05% rate 5 yr CDs with monthly interest from Wells Fargo on the secondary market listed with the same maturity date, but various prices including 99.75, 100, 100.5 etc...with various available amounts. The lowest price 99.75 did not list the APY as 5.169% like the primary offering, but it was 5.05% or just slightly higher (can't recall and site is down during transition). I was only able to buy the lowest price offer, which seems good for the buyer, so I payed $997.50 per CD I think.
My question is why is there a difference in listed APY from when it was a primary offering to the secondary offering if it has not even been issued yet? Will I still be receiving the exact same dollar amount of interest monthly as if I bought it from the primary offering? I expect to keep it until maturity and get back $1000 per CD. Or is the APY just listed differently for primary and secondary CDs at TDAmeritrade?
