I think, such sayings are more and more being proven wrong. Buy the rumor, sell the news, or buy the dip and hodl long term etc have severely backfired in recent months and many individuals(I personally know) lost huge.

Until we return to ZIRP somehow, there is just too much money in AI to keep the hype going as long as possible to avoid the investor backlash or cause mass layoffs(cutting costs and recovering because we spent too much on AI but can’t get refunds so layoff people instead), as money seem to only chase hype and due to not enough free and openly available money for other topics, all flows to only thing that everyone chases.
