Directionality of Loudspeaker Cables

Hey Folks...seasoned listener, non-engineer here...

When an amplifier sends current to a loudspeaker, the positive current is sent from the amplifier TO the speaker, then the ground RETURNS the negative electrons TO the amplifier, thus creating a circuit?  If this is correct, when one considers directionality for loudspeaker cables, the preferred direction for the cable itself, when possible (it is for me now) -- would you not point the returning negative cable FROM the loudspeaker to the amplifier? 

I recently installed a set of the wonderful Verrastar Grand Illusion Evo Series speaker cables...4 individual ribbon cables that are clearly marked for proper direction. I won't trouble you with the details, but swapping cables out ain't easy for me.  Almost all of my speaker cable upgrades have been single runs containing both + and - inside the solo cable, but now, I once again have the opportunity to test the theory.  In my excitement to install the Verrastars, I'd forgotten about this tweak from 20 years ago. 

I welcome any and all feedback, hopefully enough positive, to motivate me to swap them around.  Thanks, and More Peace.  Pinthrift

Hrrrrrmmmm...Thanks so much for your responses, especially your deep dive, Al.  In the late 90's, a friend was designing ic, speaker and power cables that competed with the expensive cables of the day.  I would R&D with him in a fine system that included Audio Matiere electronics and some heavily modded, revealing Koss electrostats.  He came to trust my ear and feedback and commonly sent me home with cables.  Frankly, I don't recall testing directionality since each of his products were clearly marked. All my speaker cables were single wrapped pairs, however, I do recall testing my old 2 PAIRS of Tara Lab Phase II cables with the pairs on the ground pointing back towards the amplifier.  I recall it being marginally better and left it at that.  Rick claimed that the extruding process left cables directional, sounding better one direction. 
I'll end with a question.  Are all loudspeaker cables sold today marked directionally, and if so, why?  Thanks again, Pin

"....We’ve already been through why wire is directional in an AC circuit a bunch of times so I’ll spare you the lecture."

No need for the lecture, but if you could provide a reference/link that would be appreciated.

"....Even the stock cheap fuses are directional. Saying they’re not is just repeating an old wives tale."

Same for saying that they ARE directional....

Many cables sold today are marked directionally, mainly for two reasons:
a) because (purportedly) cables become directional through the production process and /or their use (i.e. flow of current) and the marked direction is an easy reference for the user; b) because the shielding, when present, is connected on one end only, and that determines the directionality.
