There are 10 Charizard Pokémon cards in existence (# of outstanding stock)

Each card is worth $100 today, $1,000 total value

Tomorrow the price falls to $90, $900 total value

$100 was “wiped”

If the charizard card is worth $80, $90, $100, or $110 will continue to play out.

If it did the opposite happened and price of each card went to $110 then you could say $100 was “injected” into the market.
