Is the 'stick to the fundamentals' mantra becoming a crutch?

Been seeing a lot of folks in here, and elsewhere, clinging to fundamental analysis like it's a life raft in a hurricane. Don't get me wrong, understanding the business is crucial, but sometimes it feels like a convenient excuse to ignore what the charts are screaming. I look at something like $VNM, currently down to $17.16, having dipped from $17.255 to $17.14 today – that's a pretty clear signal, regardless of what some forward P/E might suggest. Are we so afraid to admit that sometimes price action is the fundamental? Or are we just too stubborn to adapt when the market decides to be irrational longer than we can stay solvent? Push back if you think I'm missing something obvious.
