I meant physical stock rather than stock market. If you could sell a graphics card today for £1k but it looks like if you wait it will be worth less then you will want to try and sell it before it drops.

Plus over time newer hardware comes out which is faster and then your existing stock becomes worth less due to having to compete with the new stuff. You bought all this stock and you want to make a profit or keep losses down.

What about when they know their stock is losing value

Not the same day sure, but I’d the market crashes then its reasonable to expect it to drop at some point.

Not waiting to build and I still want it to die
