I am getting the following error when using stockspec function: Undefined function 'stockspec' for input arguments of type 'double'

The code is:

AssetPrice = 50;
Sigma = 0.20;
StockSpec = stockspec(Sigma, AssetPrice);

StockSpec = stockspec(.20, 50)

I have Financial Instruments Toolbox, code

any(strcmp('Financial Toolbox', {v.Name}))

returns ans=1

Even

help stockspec

returns full documentation text output.

Therefore I am courious whether I am lacking any essential toolbox, or what else may be the cause of this problem.

The list of toolboxes I have:

MATLAB                                                Version 8.6         (R2015b)

What happens if you run the full demo, with all the optional arguments put in there, like in the documentation: http://www.mathworks.com/help/fininst/stockspec.html?s_tid=srchtitle If that runs, I'd call tech support.

A possibility is that you have the toolbox installed but not licensed. If that is the case then the "which -all stockspec" would mention not being licensed if I recall correctly.
