That is correct.

Why?  Do you have an entity called STOCK or EXCHANGE?  If not, then
that's *not* what you want to use.  It's not a matter of opinion;
&STOCK is an SGML reference to the entity STOCK (it's not even legal
XML if the entity exists, because it would need a semicolon).

HTML browsers' acceptance of the first form is a bug, not a feature,
and the use of ampersands to separate query parameters has been
deprecated since before HTML 2.0 for precisely this reason.
