Nope. Nvidia has often sold products at below the market price. This has created shortages where scalpers who are able to get some supply immediately resell above list price. It might seem stupid for Nvidia to leave money on the table that way but they don't want to burn relationships with customers by raising list prices (much).
Adjusting prices daily or weekly (in both directions) wouldn't have necessarily been that helpful for maximizing their long-term profits, though (as you said).
