# Avoid News, Part 2: What the Stock Market Taught Me about News

It\'s been a decade since I blogged about the benefits of [avoiding
news](http://www.bayesianinvestor.com/blog/index.php/2011/03/09/avoid-news/).

In that time I mostly followed the advice I gave. I kicked my addiction
to The Daily Show in late 2016 after it switched from ridiculing Trump
to portraying him as scary (probably part of a general trend for the
show to be less funny). I got more free time, and only missed the news a
little bit.

Then the pandemic hit.

I suddenly needed lots of new information. Corporate earnings releases
were too slow.

Wikipedia, Our World in Data, Metaculus, and some newly created
COVID-specific web sites partly filled that gap. But I still needed
more, and I mostly didn\'t manage to find anything that was faster or
more informative than the ~~news media~~ storyteller industry.

That at least correlated with higher than normal stress. I suspect that
paying attention to the storytellers partly caused the stress.

### Distorted Salience

Do you want to focus your attention on problems that are most likely to
hurt you? If so, the storyteller industry is likely to distract you:
![causes of death versus
interest](https://ourworldindata.org/uploads/2019/05/Causes-of-death-in-USA-vs.-media-coverage-716x550.png)

It\'s hard for a daily news source to avoid that effect. It has to focus
on recent, unusual events. When coal plants [emit radioactive
smoke](https://www.epa.gov/radtown/radioactive-wastes-coal-fired-power-plants),
there\'s little occasion to write about it, because it\'s very routine,
and not at all a sign that someone did something wrong when people
initially adopted coal. Yet when a nuclear plant emits a similar amount
of radioactive material, that\'s a rare sign of an avoidable mistake.
It\'s unclear how the storyteller industry could avoid causing readers
to pay undue attention to the nuclear mistakes. But the natural
consequence is that readers will, at least subconsciously, treat that
attention as implying more harm.

Storytellers could reduce the biases from that distorted salience, by
sounding more worried in proportion to harm implied by their stories.
But that conflicts with the goal of making their stories entertaining,
and with the goal of maximizing the number of stories that readers
believe to be important. Alas, few readers are willing to give the
storytellers incentives to prioritize that kind of balance.

### Preparing for the Pandemic

One of the bigger mistakes that I made in 2020 came from recalling that
Ebola, SARS, the 1976 swine flu outbreak, and various bird flu\'s all
generated a modest amount of news, but little harm in the US. Even the
older pandemics that did kill many Americans had little apparent effect
on the stock market. So I gave low priority to studying pandemics.

In addition, I had traded a few bird flu contracts on
[Intrade](https://en.wikipedia.org/wiki/Intrade), and I think made a
tiny amount of money betting that pandemics were less likely than people
thought.

Alas, there\'s a difference between the probability of an event and the
expected value of that event\'s effects. Storytellers, who tend not to
do expected value calculations, seemed to often overstate the
probability of a distant pandemic reaching the US. Yet they rarely imply
that the expected harm implies anything more than \"you need to stay
tuned to our channel\".

But I wasn\'t paying much attention to the storytellers at the critical
times, so I can\'t blame them much for my mistake.

### COVID fears

In the spring and summer of 2020, I saw rather large discrepancies
between my business forecasts, and the impressions that storytellers
were promoting.

It sure looked like many commentators / storytellers were going out of
their way to overstate the economic damage from the pandemic.

I presume that\'s partly due to them trying to manage people\'s fear
levels: if people felt economically safe, that might cause them to feel
it was safe to risk spreading the virus. Another reason might be that
fearful stories selling better than happy ones.

Whatever the reasons, by mid to late April enough companies were issuing
statements to the effect that the damage to their business wasn\'t
catastrophic, and that they were seeing signs of recovery. No single
report meant a lot, but I read a lot of corporate announcements, and saw
a clear pattern: business was better than most pundits were willing to
imagine.

For much of 2020, there were widespread
[claims](https://www.cnbc.com/2020/06/15/hertz-says-it-expects-stockholders-to-lose-all-their-money-in-filing-for-selling-more-stock.html)
that [Hertz shares were
worthless](https://www.forbes.com/sites/jimcollins/2020/07/07/update-on-hertz--still-worthless/?sh=6e92f96e534a),
or nearly worthless.

That conclusion was superficially plausible, as it\'s not unusual for
bankruptcy cases to work out that way. But Hertz\'s situation seemed
unusually uncertain, and the pandemic triggered some abnormally fast
business fluctuations.

It now looks like buying Hertz while it was in bankruptcy proceedings
was [a great
idea](https://finance.yahoo.com/news/hertz-equity-recover-8-share-141200112.html)
given the benefit of hindsight.

I\'m not complaining that the storytellers were wrong about what Hertz
shares were worth. They did a decent job of identifying relatively
competent sources of opinion on the subject. I\'m complaining about the
false implications about the competence of those sources. It\'s hard to
identify an expert who could convincingly report that nobody had the
foggiest idea what would happen (unless you\'re willing to treat market
prices as expert opinions - in which case, why are you paying attention
to a story instead of just looking at the price of Hertz stock?). Hertz
ought to have been almost that expert, but legal risks pressured Hertz
to slant it\'s comments in a more paranoid way.

Hertz\'s value ended up depending somewhat heavily on when vaccines
became available. That\'s an important topic where the storytellers
failed badly. E.g. [this
headline](https://www.nbcnews.com/politics/donald-trump/fact-check-coronavirus-vaccine-could-come-year-trump-says-experts-n1207411)
claiming to be a \"fact check\" that said we\'d need a miracle to get
vaccines in 2020. That was in mid-May, when
[Metaculus](https://pandemic.metaculus.com/questions/4064/when-will-a-sars-cov-2-vaccine-candidate-demonstrate-an-efficacy-rate-75-in-a-n500-rct/)
was showing a significant chance that a vaccine would be proven
effective by the end of 2020.

Some storytellers even spread the false claim that [We\'ve never made a
successful vaccine for a coronavirus
before](https://www.abc.net.au/news/health/2020-04-17/coronavirus-vaccine-ian-frazer/12146616).
If you read the story carefully enough, you will notice it eventually
hints at the caveat \"in humans\". Vaccines for coronaviruses have been
commercially available for [several
species](https://coronavirusexplained.ukri.org/en/article/vdt0010/) of
[pets and
livestock](https://www.intvetvaccnet.co.uk/blog/covid-19/lessons-veterinary-coronaviruses).

It took me a couple of months to see through that vaccine smokescreen.
Doing so helped me to make lots of money in the second half of 2020
betting on pandemic-sensitive stocks (not Hertz), since most investors
were too pessimistic about vaccines for much of that period.

### Enron

[Enron](https://en.wikipedia.org/wiki/Enron#Misleading_financial_accounts)
is an example of why I mostly ignore stories, and focus on verifiable
numbers.

I heard a glowing report of Enron\'s innovative management style in
mid-2001 (at [Extro
5](https://reason.com/2001/06/20/live-from-extro-5/)), and likely would
have noticed more such reports if I had been more addicted to
storytellers. That report sounded plausible, and it would have required
an unusual amount of effort for me to find anything wrong with that
story. When I thought in terms of stories about Enron management, I felt
a real temptation to buy Enron stock, and those stories would have
seemed more salient if I had paid more attention to the storytellers.

Then I looked at Enron\'s earnings growth, revenue growth, and return on
equity. The revenue growth was fairly impressive, but nothing about the
earnings distinguished it from a boring company.

I also looked at charts of its stock price. I saw signs that sellers
were less patient than buyers. That usually indicates an ordinary
fluctuation in business, but whatever, it counted as evidence that I
could safely postpone buying, so I decided to wait. I kept waiting until
it had clearly collapsed.

### Coping Strategies

My most important strategy for getting good stock market information is
to decide what information I want, to actively seek it, and to minimize
my attention to what other people suggest I should pay attention to.

If I let the storytellers decide what evidence to use in evaluating a
company (or an industry, or the economy), I\'ll end up using criteria
that are selected for other people\'s purposes. Sometimes those purposes
will be ideological, sometimes they will be to protect some powerful
institutions, or maybe they\'ll be mostly for entertainment purposes.
The results are mostly not much better than letting one side of a court
case choose which evidence I should look at.

More generally, I try to focus on sources that prioritize accuracy over
entertainment (e.g. Wikipedia, Metaculus).

Alas, that requires some willpower. I haven\'t managed to develop a
consistent habit of looking at sites like that for information.

I also have some need for alerting myself to important events that
aren\'t on my radar. The Wikipedia [Current events
portal](https://en.wikipedia.org/wiki/Portal:Current_events) is such a
source, but isn\'t wise enough about what\'s important to be a complete
answer. I check news.google.com, but it\'s click-baity enough that I
keep hoping to replace it with something better.

Individual bloggers sometimes provide news-like benefits, especially
when they\'re aiming to earn respect from well-informed peers, rather
than any of the strategies which require attracting lots of readers.
[Scott Sumner](https://www.econlib.org/author/ssumner) often meets those
standards.

I\'ve gone back to reading Tyler Cowen. He does a better job than
Wikipedia of identifying important topics, but is much harder to skim -
I can\'t get much out of his blog without getting sucked in to spending
more time there than I want.

### Is it Getting Worse?

When I was young, there were fewer choices for how to get the knowledge
that storytellers aim to provide. People chose between maybe three TV
stations, and one or two newspapers.

That meant less competition than we have today. Less competition meant
that storytellers had more freedom to write stories that enhanced the
storytellers\' reputations with their friends and families. That created
a modest tendency toward high-brow, consensus-oriented stories.

For example, the U.S. had [many bombings in
1970s](https://status451.com/2017/01/20/days-of-rage/), often
politically motivated. The storyteller profession was able to treat
those as ordinary crimes, that we could mostly forget because the police
were able to contain the harm to relatively minor levels.

Whereas today, we have storytellers that specialize in peddling outrage.
At least some of them will have ideologies which will predispose them to
overstate the importance of politically motivated crimes. Even those who
are predisposed to downplay the importance will have some incentive to
hype the stories in order to keep readers who are attracted to
controversy.

Yet we also have information sources that replicate the high-brow,
consensus-oriented features that newspapers and TV stations used to
provide, e.g. Wikipedia. So my conclusion is that people who really want
good information are better off today, but the average person\'s
information diet is likely getting a bit worse.

P.S. I don\'t want to leave you with the impression that storytellers
are mostly wrong. If they were, I could make more money by doing the
opposite of what they say. Their actual track record is much more
ordinary than that.
