What has changed materially between Friday and Monday?

Nvidia still has the greater hardware and infrastructure. Their position has not changed. If the narrative is that a small startup was able to outperform these large corps with less tech, then wouldn't the flip side of that be that the potential of Nvidia's current position is massively underrealized? i.e. If Deepseek can do more with less, why wouldn't Nvidia be able to do more with... more?

Here's what I think is really happening:

Institutions have been drip feeding Nvidia stock to retail all of 2024, slowly bringing the price up. Then, they manufactured a narrative around this (massive) breakthrough in order to shake out retail and buy back the same stock at discount.
