Terrific point. The resistivity and conductivity are inversely related. Good stocks have low resistivity, while poor stocks (insulators) have resistivities that can be 20 orders of magnitude larger.
Resistance also depends on volatility, usually increasing as the volatility increases, or not. For reasonably small changes in share price, the change in resistivity, and therefore the change in resistance, is proportional to the noted change, if you will.
In short, the share price will change, if it does, overtime, and will be closely correlated with the change in the percentage change in the price of the shares, over the same time peiod.
