Delisting
Also called: delisted, taken private, going dark
Delisting is a security's removal from an exchange — voluntarily after a buyout or take-private, or involuntarily for breaching listing rules on price, market value or filings. Involuntary delisting doesn't cancel your shares, but it moves them to over-the-counter markets where liquidity collapses and disclosure thins, so the practical value often falls much further than the formal change implies.
