In case anyone got lost in the above explanation (and I am sure there are a few IR guys out there who would be lost), let me remind everyone that a bid is not some random, computer generated number that market makers collectively agree upon and the beginning of each trading day and then update throughout the day based on volume and the ratio of buyers to sellers.
No! Surprise, it is not that.
A bid represents an unfilled order of a real person willing to buy a certain amount of that particular stock at a specified price, no higher.
A cheapskate, if you will.
Just as an ask represents an unfilled order of a real person willing to sell (offer) a certain amount of that particular stock at a specified price, no lower.
I wish this was on every board on IHUB. I'm sick of reading about MM manipulation, shorts, etc as excuses for why a stock is declining as the bid drops. But never here a peep about such as it rises.
