For one thing, by today's standards that kinda stuff sounds like the investment advice equivalent of "just walk into businesses, give them a firm handshake, and ask for a job". Anachronistic to the point of sounding like satire.
Market value is untethered from business fundamentals, has been for a long time, anyone telling you otherwise can go listen to Jim Kramer or whatever. You as a consumer thinking a product is good has fuck-all to do with a company's stock price (and therefore, fuck-all to do with that stock being a good buy - anything that you've observed that happens to line up is closer to happy coincidence than "informed strategy").
And regardless, the comment I'm talking about had you claiming one could simply offset Netflix's rising price by buying their stock - there's just so, so many things to disagree with in that statement. I chose the one that the person who seemed to take that seriously needed to hear, so as not to burden the thread with my ideas about all of it.
I can do that now, though, if you really insist.
