Five Reasons Why The Stock Market Is A Really Weird Place To Invest

Investing your hard earned dollars into the stock market is probably the most common way to save for retirement these days, but investing takes plenty of faith (as discussed in a previous post).  Market crashes and giant bull markets happen.  Black Swan events.  Weird stuff happens all the time.  Things you wouldn’t expect, and events that defy logic.  There’s even times when investing theory and the real world just completely disagree!

What kind of “weird” stuff am I talking about?  Read-on to find out…


1. Stock Prices Fluctuate More Than The Underlying Businesses

The first oddball on my list is around the fact that stock prices can fluctuate wildly in a given year.  By itself this doesn’t sound all that strange, but remember that stocks will commonly fluctuate plus or minus 50% in a given year.  This kind of large price movement is not unusual in the stock market.

Meanwhile, the underlying business doesn’t see profitability swing nearly as much.  Under most normal circumstances, the underlying business might only see gains or losses in profitability of 10-20% in a given year.  Relatively small movements compared to the stock market.

To a private owner of a business, one or two bad quarters wouldn’t wildly effect how they might value the business.  Sure, a bad quarter isn’t idea but that private owner wouldn’t sell his company for 50% less just because of a bad year.  Yet this is exactly what Mr. Market does on a regular basis.

Wall Street Traders
They might not look emotional now, but when the tide turns… Wall Street can go a little off the deep end!

It happens because Mr. Market overreacts with emotion about whatever news might be affecting the company on a given day.  Businesses by their very nature are NOT emotional.  The employees get up everyday and simply head to work to do their jobs.  The machines that power the business will emotionlessly run until repairs are finally needed.  A properly run business is like a machine — about as unemotional as you can get.

Meanwhile, the stock market is a collection of people buying, selling, and prognosticating about what the future might hold.  Fear and greed run rampant on Wall Street — it’s an emotional roller coaster that wildly fluctuates around the true value of a business. (Both positive and negative)


2. Mutual Funds And Index Funds Outnumber Stocks

Here’s a strange and interesting fact — The number of public companies listed on U.S. stock exchanges is around 3600 companies.  This number has declined considerably since the 1990’s.  This fact is interesting in itself, but what’s more interesting is that the number of index funds now outnumber the number of stocks.  There are now over 10,000 index funds and mutual funds traded in the United States!  Holy Cow!

What are all these mutual funds and index funds doing to earn money for their investors?  They’re investing in many of those same 3600 companies!

What is Wall Street really selling? Investments or Investing Products?

These facts really showcase just how Wall Street earns it’s pay — by selling investing products!  Index funds happen to be the current fad.  Wall Street is just following the money…. even if profits from index fees aren’t as large.

Reportedly Vanguard now manages over 5.1 trillion for investors.  Clearly, even with those low fees, no-one at Vanguard is starving!


3. Bigger Stock Returns Don’t Require Bigger Risks

Here’s a common belief about investing that’s wildly held, but might very well be wrong — The believe that bigger rewards require bigger risks.

I personally define a “big reward” as any return that can beat the return of the S&P 500.  In 2018 the S&P 500 lost 4.38%, so that hurdle wasn’t a gigantic one.  Meanwhile some of the biggest and *least* risky stocks in the market made very sizable returns in 2018.

  • Microsoft (MSFT): 18.74%
  • Disney (DIS): 1.9%
  • Google (GOOGL):  -0.8%
  • Visa (V): 15.72%
  • Mastercard (MA): 24.64%
  • Verizon (VZ): 6.22%

See what I mean?  These are all HUGE companies that offer very low risk of failure.  Microsoft and Google have zero risk of disappearing tomorrow, as do Visa and Mastercard.  Disney isn’t going anywhere as a titan of the entertainment business.  And Verizon?  Nobody’s going to stop using their phones tomorrow.  These are all extremely low risk investments that still managed to earn very good returns in 2018!

This wasn’t just 2018 either — many of these low risk companies have clocked-in market beating returns for years. 

Risk doesn’t seem to be closely correlated with return as we’re often taught.

Why?  Risk is not necessarily correlated with the ability to compound money.  Some of the least risky companies in the world know how to compound money incredibly well, and they do so with very little risk.

Theoretically risk and return should be correlated, but in the real world low risk seems to often provide greater rewards.  There’s even a recent study of Warren Buffet’s stock investments that discovered he actually achieved his outstanding results by actually making lower risk investments.  Weird but true!


4. You Don’t Need To Be Smart To Invest Well

Imagine that you’re able to bring together 16 of some of the smartest financial wizards on the planet to form a hedge fund.  Some of these people are so smart they’ve even won Nobel prizes!  Just an incredible amount of experience and intelligence brought together to do one thing — invest.

Now you’d expect all those smart folks together in the same room should be able to earn a decent return… right?

This is the story of Long-Term Capital Management (LTCM), a hedge fund started in 1994.  At first the returns looked great — Investors in the fund were earning around 30% per year.  Fantastic returns, right?  To do this, LTCM used a lot of leverage — reportedly leverage as high as 25 to 1.  By 1998 the firm had lost $4.6 billion dollars and needed to be bailed out in order to pay their debts.

This incredible blunder absolutely destroyed LTCM and lost investors a lot of money.  It’s a fantastic example of how even incredibly intelligent people can make dumb investing mistakes (like using too much leverage).

If you’re curious, this story is told in much greater detail (and better than I could ever tell it) in the incredible book When Genius Failed: The Rise And Fall Of Long-Term Capital Managment.

But wait, there’s more!  I recently learned the story has a Part 2! — Apparently, after LTCM shut down some of the principal individuals in LTCM decided to form a new hedge fund called JWM Partners.  This hedge fund used many of the same complex investing strategies as LTCM.  Only this time they planned to use less leverage and manage risk better — reportedly using only 15 to 1 leverage.

How did it work out?  Well, the firm was shut down after realizing very large losses in 2018.  Genius failed twice!

Being super smart is great, but it doesn’t necessarily make you a better investor.  Maybe investors should simply focus on avoiding dumb mistakes.


5. Bigger Companies No Longer Equate To Longevity

Size usually means strength. Dominance, and lasting power.  That’s what our lizard-brains are wired to believe anyway.  It used to be that investing in public companies worked this way too — you’d pick the largest and most dominant firm and then hold it for as long as possible.  These firms had wide economic moats that kept smaller companies from attacking their business.  These companies lasted for decades, and most investors did extremely well investing this way.

It’s classic buy and hold investing strategy.

But then something happened in recent decades — the average lifespan of an S&P 500 company (the largest and most dominant publicly traded firms) started declining.  Now, the average lifespan of a S&P 500 firm has been cut in half.  The average lifespan is only 18 years.

s&p 500 life span

The reason?  Innovation and disruption.  Newer more nimble companies are out-innovating and then replacing old-school firms at a faster rate than ever before. One good example of this might be a company like Amazon out-innovating the old-school bookstore chains.

I guess brand loyalty doesn’t count for much these days.

This is a trend I mentioned when I looked at the lessons learned from the Kraft-Heinz merger.  Consumers just aren’t as interested in old-school brands anymore, and large firms like Kraft-Heinz haven’t been able to innovate or keep-up with new consumer preferences.

The speed of all this disruption has been increasing too, and it probably has something to do with the internet.  According to Forest Research, about 13% of all U.S. retail sales are now online, and that’s projected to rise by 17% in 2020.  That’s incredibly fast growth!

Innovative technology companies now dominate the top 12 S&P 500 firms.

What does this mean for investors?  Faster stock turnover than ever before.  For example, if you own a S&P 500 index fund this faster turnover means the index fund will be buying and selling companies faster than ever before. This could potentially mean higher taxes for investors!

On the flip side, it also has the benefit of insuring you’re always invested in the most innovative new companies taking market share from the big-slow dinosaurs!


Final Thoughts

The stock market is a pretty weird place.  Many of the things that we believe to be true about investing just aren’t the way things work in the real world.  Investing often defies logic.  So how can the average investor ever succeed?

One of the most important lessons we can learn from all this “weirdness”is to never stop learning.  What’s true about investing today likely won’t hold true tomorrow.  It’s always changing.  You just have to keep learning and adapting.

Embrace the weirdness!  Investors can either choose to continuously “update” their own thinking, or risk falling behind.

Is there any stock market weirdness I missed?  I’d love to hear about it in the comments!

    Great post, I didn’t know the # of stocks had gone down that much!

    As for the “bigger returns don’t require bigger risks”, I see your point but one of your examples listed still has big risk (my opinion). Sure, Google isn’t going away, but most of the prospective Democratic Presidential candidates have been open about breaking up major tech companies. It could happen.

    Also, Google has yet to be hit with a major hack that’s hit most the big tech companies. Imagine if we woke up one day and found out most or all of Google username and passwords were stolen? It could happen. It wouldn’t be good for their stock obviously. My main point is that as big as Google is, I don’t consider them “blue chip” like Disney or Verizon since they operate at more of the bleeding edge. Again, I’m sure most folks disagree with me

      It’s interesting you bring up Google and anti-trust possibilities. If you remember, the very first company on my list (Microsoft) was once under anti-trust scrutiny.

      Yet today Microsoft is larger and more profitable than ever.

      Here’s a question: When was the last anti-trust breakup of a company? AT&T in 1982. Breakups are actually quite rare.

      • June 17, 2019 at 3:24 AM

        You’re absolutely right, MS came back stronger and we haven’t had a breakup since AT&T. That’s why I said my opinion of Google is just my opinion and probably wrong 🙂 But something in my weird head says it might be different with them because they have so much personal/private data bout people and use it so, ugh….., suspiciously. Overall I agree Google is probably a safe investment, but we’ll see.

          Even with a forced break-up it could be a profitable investments. The different parts of Standard oil after the break-up did VERY well and so did the baby bells. With a break up shares of the spin off compagnies are often divided among the investors so from an investor view point you can see it as being the owner of a holding compagny (before break up) or having shares in three different compagnies (after the break up). Is there really a difference for you as a share owner?

    The fact that market prices aren’t based on actual business performance has always been one of the weirdest parts of investing to me.

    It’s great because Mr. Market can exist but damn its weird that nothing is tethered well to reality. Oh well just wait for others to be fearful…and hope they don’t get so fearful the world collapses. 😛

    Great post, I recall seeing a table similar to Table 3. The rise and fall of companies like GE and Sears is eye opening. Never knew about that mutual/index fund stat…very interesting!

    Thanks for this post, I enjoyed it.

    The market is weird, irrational, and moody like a hormonal teenager. It over-reacts to rumors and then often overcompensates.

    I’d still venture that in the long run, the market overall will do better than putting faith in a smaller selection of companies, no matter how stable those companies seem.

    And in paragraph 3, I think you mean “unusual,” not “usual”?

    That’s why you shouldn’t pay too much attention to noises. Often the market prices aren’t based on actual business performance. There’s definitely a lot of emotions when it comes to investing.

  • June 19, 2019 at 7:46 PM

    Good point about previous “blue chip” companies no longer having such a stronghold. Disruptive technology and companies are popping up and Amazon was the perfect example.

  • June 20, 2019 at 12:25 PM

    Nice post! I liked how you talked about the changing strategies of the market and what applies today may not apply tomorrow. Just like many technology and investing fields you must be ready to adapt or be left behind.

    good post! the question is if index is the new fad, then where should we invest?
