Yes I'd say so.
How you call it, symmetric wrt x (time) axis ? (a reflection, like a mirror image)
y=f(x)
y=- f(x)
(or more in general y=- a f(x) + b, a>0)
Like pairs of inverse ETFs (eg SDS/SSO). Example:

http://www.stockrake.com/inverse-etfs-inverse-mutual-funds-and-inverse-etns~2007~09.html
http://etfdb.com/type/equity/inverse/
etc.
[Problem is that even that, I am afraid, wouldn't help much probably ... ]

Quote from shikantaza:
y=C-X (where C is a constant) is "specular" of X?. If not, please define "specular", preferibly with a graph, picture or drawing.
