@hughesmaxwell it does not matter the sector...a pump and dump is when the price it pumped up from some type of news catalyst over a course of days weeks even months... then sold off going back to pre pump numbers... I agree with you it’s usually done in penny stocks or small caps but the big boys do it as well ... Apple is doing it as we speak... but the volume is the “tell” when a stock flies up with 11m shs but normally avg 2m shs that my friend is a pump there is no way the price level can be sustained without the volume being above average everyday but if they do it that way then they let the cat out of the bag...imo
