Thx. So to be sure: If say, a lot of people want to sell, but *nobody* buys, the stock prices *would not fall*, would they? (If there is no trade made.)

If there is no trade made, then nothing happens... once one side "blinks" and a trade is made, then you can say something happens

Ok. Thx for clarification. And vice-versa: If some stock "lost value" it means that at least *one trader* actually sold for that price (and one buyer bought)?

The 'last price' is not the only approach to find the price. Typically when you hold an instrument and want to 'mark to market', ie use the market price, you Wil use the bid price, because that's the price you would be able to sell it at. When you want to buy an investment, or you are short, yous should use the bid price. Some systems also allow you to use the midpoint between the bid and the ask.

# How are final stock prices arrived at?

(Asked by: username_0 on 2018-09-28)

'Everybody' knows that prices are generally governed by offer & demand, but I am wondering on the details of the stock exchange here.

How are stock prices (the ones which are nicely listed every day in charts) are actually computed to a specific number based on various simultaneouse bids?

Do they change, if no transaction is actually taking place (but there are bids)?
And how are concurring bids dealt with?
