Art as investment - thoughts

As talk swirls around the fact that some art dealers are doing the unthinkable and slashing the prices of artists they represent, Wooster Collective has an interesting observation on the 'art as investment as opposed to art for art's sake' conundrum:

"As an investment, art should be treated no different than a stock. Investments go up and down. Why shouldn't art? On the flip side - If you buy art not as an investment but because you love it, why should it matter to you if the price comes down? You bought it because you loved it, not because of it's value."
