In finglish, we are a high beta stock, which essentially means that we have a much much higher volatility than the broader market. So you're right, if the market is down x%, we should theoretically be down (e.g.) (3x)%, but instead we are only down (0.5x)%, then a case can be made to say that we have just beaten the market today by (2.5x)% instead of the salient (0.5x)% that everyone can see.

Or alternatively, if you don't have the inclination for financial mumbo jumbo, you can just look at the fact that we have sole dibs on an industry revolutionising technology that has just been proven to work under full scale testing conditions (which are presumably more demanding than normal operating conditions) in an industry that is undergoing unprecedented expansion, which means that the only long term direction that we can plausibly go is up.
