18 Chart Crimes and Misdemeanors

By Sloane Ortel Posted In: Leadership, Management & Communication Skills, Philosophy, Quantitative Methods

Truth is relative, falsehoods are seductive, and shortcuts are commonplace.

Chart crimes are a clear manifestation of this. These badly built graphics are blunders at best.

Most commonly, they are financial fake news. It’s not an antidote, but I think awareness will help counter this subtle phenomenon. As far as I can tell, the expression “chart crime” entered finance Twitter’s orbit after Reuters journalist Eric Burroughs began using it in February 2015.

Connoisseurs always have their favorite category, and I’m no different.

This is, like, the Macbeth of chart crime.

Everything about it is perfect. The Y axis is scaled so that a 3% contraction of the US Federal Reserve’s balance sheet looks like a fire sale.

It may well be that the person who made it was just busy. Anybody who produces analytical work has created something that doesn’t quite come across the way it was intended. That’s the nature of taking intellectual risk. Whatever else this graphic is, it’s not helpful. It leaves the reader believing in an apparition.

Thankfully, the nature of social media allows observers to check these behaviors in the marketplace of ideas. It’s both helpful and appropriate to do this, but it doesn’t quite generate the same level of engagement as the misrepresentative masterwork that preceded it.

And it also doesn’t mean people will stop making them.

Like Macbeth, this same story just keeps being told with a different cast. Whether you’re watching a version starring Patrick Stewart, Michael Fassbender, Peter O’Toole, or Toshiro Washizu, pretty much everyone still dies at the end. And yet it continues.

This innate desire for big, newsworthy charts can contort some commentators’ output, turning them into brands built around bad news. It can be hard to contravene as an observer, especially because the corpus of crimes only gets more subtle with additional study.

Indulge me in a thought experiment: Let’s assume the chart above is 100% true. What to do with this information?

One supposes we’d sell everything. When Holger Zschaepitz tweeted this on 9 February 2018, the Dow Jones Industrial Average had just concluded a 2,500-point selloff. It would go on to rally for most of the month, and has since gone back and forth to sit right around the same place.

Aren’t you glad to have hypothetically sold?

The thing about these analog charts is that they raise a specter instead of presenting an argument.

They get brought up relatively frequently, often inspired by a viral clip of Paul Tudor Jones II in the 1987 documentary Trader. In the clip, a youthful Jones and his colleague Peter Borish go short right before the crash. They get a 62% monthly return to show for it, and earn the moniker “legendary” in the process. The analog helped them generate the conviction to put on an aggressive position. Doesn’t that mean it’s a legitimate form of analysis?

Well maybe for some great traders, but for most of us, it’s just a recurring distraction.

It really is shocking how often these surface, and how surface-level their implications are.

I could probably find dozens of these overlay charts. But there are so many more excesses to curate.

Say whatever you want about the charts above, at least all of them actually have a Y axis.

Amazing things can happen when information is presented without the grounding influence of a clear vertical scale.

I’ll grant that a flexible capital structure is an advantage, but think about what this chart is really doing. It shows the evolution of leverage ratios over three fiscal years from 4.8x debt/adjusted EBITDA to 3.2x. But just glancing quickly at the area of each entry on the bar chart, you’d think management has entirely changed its attitude towards leverage. The 12-month figure for fiscal year 2017 looks like 10% of the value two years prior. It’s really two thirds.

But again, at least the chart has labels.

So far as I can tell, the only one in this classic from my colleagues at Barbarian Capital is “the growth.” And I hate to quibble, but five years of growth in whatever this is from 2013 to 2017 looks like just a lot of running in place to my eye.

And it turns out that’s a theme.

Sales-y corporate nonsense is one of the major categories of chart crime. And if you are an investor-relations professional, you ought to be aware that idiotic infographics produce much more than aesthetic objections in the analyst community.

They also heighten skepticism, take readers out of your presentation, and ultimately produce more work.

This presentation slide reminds me of how Jeff Bezos reportedly banned presentations from his senior team meetings to increase efficiency. There’s even a Swiss political party dedicated to its abolition that argues presentation technology imposes an annual cost of 2.1 billion Swiss francs.

I want to work towards a future where such initiatives are successful.

The present is often disconcerting.

Let’s deconstruct this chart: Where did its creator go wrong?

I’d argue the original sin is in trying to squeeze too much information into one place, which it turns out is a common issue.

A protip: If you find it necessary to invent a new visualization paradigm for your currency coverage, you might be concentrating on the wrong problem.

The opposite mistake — too little information in too much space — is less prevalent but still problematic.

The main reason this chart is bad is that its creator wanted to present something other than the information in front of them.

Fight that urge.

Also worth fighting is any impulse to present a conclusion when you only have information.

Most often, it’s the color scheme or our capabilities that fail us. WebMD reckons 5% of men are red-green colorblind. So one in 20 men can’t process our profession’s prevalent color scheme.

Uncertainty also takes art to convey in graphical form. Falling victim to these complexities isn’t necessarily criminal.

It is something you want to avoid though.

When the reaction upon looking at a chart is “What am I seeing here?” it’s clear there’s a problem even if no explicit rules have actually been broken.
