You forgot to include exchange listing (top exchange) like binance
i know this days just the mention of binance in a project bring so much hype and when a project is listing on binance usually brings about massive pump but this does not happen all the time,
nowadays, news like token swap, mainnet don't move price that much, i guess people are already use to such news, the only exception will be a big partnership announcement with a well known company, sometimes pump occurs without any serious news involved.
