@JeremyWhittaker The data is not trash, it shows the top of the book on the IEX exchange, which is only one of the many exchanges. If you see for example bid $305 - ask $330 on that single exchange that means there is someone, who is willing to buy that security for $305, and another someone, who’s willing to sell it for $330. All trades must happen within this range. But, crucially, other exchanges might have much better rates, e.g. someone on another exchange might be selling for $320.
These are the spreads on BRK.B today. I find it hard to believe Berkshire baby B’s have a spread of 141 points on a stock that is worth $324. That’s a 43.5% spread.
Or look at any of these stocks. these spreads are absurd.
