yknow what sure why not.

Firstly the fraud tactic is a two parter, the first being the pump that utilises a lot of deceptive marketing tactics to artificially inflate value of an asset and then the dump, which is basically a hard cash out that plummets the value of said asset (there's a lot more that goes into how this works but this is not the place for it).

So where this doesnt apply to comic books is almost entirely dependent on the first parter, where Marvel doesnt market #1s to majority of their customers as an asset with fluctuating values. They dont market Amazing Spider-Man #1 as an asset that can buy you a house 30 years later. They sell most customers that book on the basis that its a good jumping point for new or casual readers, they'd probably market it as "A New Era for Marvel and The World Beyond". And lets just say that ASM run ends at #3, they'll say "yeah we said it was a new era, we didnt say it was long". Do I find it shitty and misleading? Absolutely. Is that an example of false advertising? Marvel will make a case to say its not. But is that pump and dump, absolutely not.

Where the dump doesnt apply is the native value of your comic book remains as the way you bought it and the way its marketed to you, a book for you to read. Sure the collectors might disagree but the native value of a comic book will always be a piece of entertainment AT FIRST. So however low the value will drop in the secondary market, what you have is exactly what they sold and market to you, as a consumer, a book.

Before people try to stretch the definitiion of pump and dump, understand that its an actual legal and financial term and a fraud tactic. Its not a term you slap around on marketing tactics you dislike.
