This is incorrect. There needs to be large investors willing to buy at $140 in order to say the CFO failed. There likely wasn't. You can't compare the actions

This is incorrect. There needs to be large investors willing to buy at $140 in order to say the CFO failed. There likely wasn't. You can't compare the actions of "smart money" like Fidelity, etc to a small investor swept up in the speculative mania and buying 50 shares at $140. Those are the ones propping up the prices until the big money deems it safe enough to buy large volumes.
