Am I understanding this correctly, that you judge market rationality on NVidia over the period of 1 year, absolute bubble rally ? Even with those materialized earnings, as you say, the market valuation is still at >30 times those earnings (and I'm being very generous by extrapolating this quarter earnings, not the past year). There is a reason for the saying "the market can stay irrationnal for longer than you can stay solvent". One should not short bubbles. But it's still a bubble ! EDIT: It's a bubble in NVidia valuation. Per se, it's a very good business, generating huge amounts of $.
