    It looks like it because the Y axis doesn’t start at zero.

    If it went to zero, then yes that would be a textbook example.

    When we had to print stuff out it could be defended, but even then I’d like it to start at zero and show a break to jump up.

    If being zoomed out to zero means it erases the change being shown, then that matters. Not zeroing the y axis can make anything look crazy.

    I dunno, I’m a stats nerd, I’ll rant about it every time I see it.

        I know it seems pedantic, but I think it’s rise in use especially with stock prices has a large effect in people’s minds and has helped usher in the stock culture where numbers must always go up and any dip is death.

        Like, you know those studies about how language shapes people’s minds and more communal languages lead to people who often think of others and prioritizes the group?

        I think y axis graphs not starting at zero is leading to decades of financial analysts obsessed with the most minute changes and drastically over reacting to anything that happens, even if stepping back to a 0 Y graph the change wouldn’t even be noticeable.

        Obviously I’m not mad you linked it, it gave me a chance to vent about this stupid graph.

        I’m pissed CNBC is doing it, they have people that know better but this graph is more sensationalized so that’s what they ran with.

        The thing is this shit has real life consequences and our economy is fundamentally built on people’s opinions. If people get scared of investing in general because of zoomed in graphs and panic sell, it could domino into an actual crash.

        Like, you ever have one of those days where you think Nero was smart for just kicking back and watching the show and Cassandra was the crazy one because she never stopped trying to explain what she thought was obvious?

      There is nothing about “the dead cat bounce” that requires it to going to zero, only that it be a long term falling pattern with a brief uptick at some point. . . which we’re arguably seeing today.

      However, the real problem is not so much the Y axis, as this is extremely typical of ticker views, but the X axis, as this is “downward trend” is being viewed over just one day. It hides the fact that the stock is up 50% in in the last month. I doubt Trump is sweating this drop too much.

      We’re once again seeing how easily manipulated lemmy users are, and how little they actually look into anything themselves, or how quickly the rush to conclusions about things they don’t understand.

        Lemmy users are, for a large part, former or concurrent Reddit users who did not like some action or another taken by the corporate administration of that platform, it would be a mistake to assume that they are somehow less liable to manipulation or jumping to conclusions that users of other social media merely on account of a somewhat anti corporate slant

          While I absolutely agree, I find the “average poster” here to be at least as gullible as the average redditor. But not quite as bad as the “average /r/conspiracy” poster, but getting pretty close. My experience seems to be the more adamant people are about their beliefs, the more open they are to confirmation bias.

        This was kind of my opinion. I don’t pretend to know a lot about stocks, but when I look at a 1Y view and see the stock had doubled, and like you said a 50% increase in the last month, this looks less dramatic. I don’t doubt it has something to do with a negative reaction to his latest rally, but I’d wait at least a day or two before I assumed this was a major setback for his stocks. Obviously, I’m not day trader material.
