I have often written about the emotional and psychological factors that inhibit long-term investment performance (most recently here). Despite repeated studies that suggest investors should just buy “passive index” funds and“hold on” until eternity, the reality is that it simply does not work that way.

If you were raised in a religious household, or were sent to a Catholic school, you have heard of the seven deadly sins. These transgressions — wrath, greed, sloth, pride, lust, envy, and gluttony — are human tendencies that, if not overcome, can lead to other sins and a path straight to the netherworld.

In the investing world, these same seven deadly sins apply. These “behaviors,” just like in life, lead to poor investing outcomes. Therefore, to be a better investor, we must recognize these “moral transgressions” and learn how to overcome them.

The 7-Deadly Investing Sins


Wrath – never get angry; just fix the problem and move on.

Individuals tend to believe that investments they make, or their advisor, should “always” work out. They don’t. And they won’t. Getting angry about a losing “bet” only delays taking the appropriate actions to correct it.

“Loss aversion” is the type of thinking that can be very dangerous for investors. The best course of action is to quickly identify problems, accept that investing contains a “risk of loss,” correct the issue and move on. As the age-old axiom goes: “Cut losers short and let winners run.”


Greed – greed causes investors to lose more money investing than at the point of a gun.

The human emotion of “greed” leads to “confirmation bias” where individuals become blinded to contrary evidence leading them to “overstay their welcome.”

Individuals regularly fall prey to the notion that if they “sell” a position to realize a “profit” that they may be “missing out” on further gains. This mentality has a long and depressing history of turning unrealized gains into realized losses as the investment eventually plummets back to earth.

It is important to remember that the primary tenant of investing is to “buy low” and “sell high.” While this seems completely logical, it is emotionally impossible to achieve. It is “greed” that keeps us from selling high, and “fear” that keeps us from buying low. In the end, we are only left with poor results.


Sloth – don’t be lazy; if you don’t pay attention to your money – why should anyone else?

It is quite amazing that for something that is as important to our lives as our “money” is, how little attention we actually pay to it. Not paying attention to your investments, even if you have an advisor, will lead to poor long-term results.

Portfolios, like a garden, must be tended to on a regular basis, “prune” by rebalancing the allocation, “weed” by selling losing positions, and “harvest” by taking profits from winners.

If you do not regularly tend to a portfolio, the bounty produced will “rot on the vine” and eventually the weeds will eventually reclaim the garden as if it never existed.


Pride – when things are going good don’t be prideful – pride leads to the fall. You are NOT smarter than the market, and it will “eat you alive” as soon as you think you are.

When it comes to investing, it is important to remember that a “rising tide lifts all boats.” The other half of that story is that the opposite in also true.

When markets are rising, it seems as if any investment we make works; therefore, we start to think that we are “smart investors.” However, there is a huge difference between being “smart” and just being “along for the ride.”

Ray Dalio, head of Bridgewater which manages more than $140 billion, summed it up best:

“Betting on any market is like poker, it’s a zero-sum game and the deck is stacked against the individual investor in favor of big players like Bridgewater, which has about 1,500 employees. We spend hundreds of millions of dollars on research each year and even then we don’t know that we’re going to win. However, it’s very important for most people to know when not to make a bet because if you’re going to come to the poker table you are going to have to beat me.”


Lust – lusting after some investment will lead you to overpay for it.

“Chasing performance” is a guaranteed recipe for disaster as an investor. For most, by the time that “performance” is highly visible the bulk of that particular investments cyclical gains are already likely achieved. This can been seen in the periodic table of returns below from Callan:

I have highlighted both the S&P 500 Growth and Emerging Market indexes as an example. Importantly, you can see that investment returns can vary widely from one year to the next. “Lusting” after last year’s performance leads to“buying high” which ultimately leads to the second half of the cycle of “selling low.”

It is very hard to “buy stuff when no one else wants it” but that is how investing is supposed to work. Importantly, if you are going to “lust,” lust after your spouse – it is guaranteed to pay much bigger dividends.


Envy – this goes along with Lust and Greed

Being envious of someone else’s investment portfolio, or their returns, will only lead to poor decision-making over time. It is also important to remember that when individuals talk about their investments, they rarely tell you about their losers. “I made a killing with XYZ. You should have bought some” is how the line goes. However, what is often left out is that they lost more than what they gained elsewhere.

Advice is often worth exactly what you pay for it, and sometimes not even that. Do what works for you and be happy with where you are. Everything else is secondary and only leads to making emotional decisions built around greed and lust which have disastrous long-term implications.


Gluttony – never, ever over-indulge. Putting too much into one investment is a recipe for disaster.

There are a few great investors in this world than can make large concentrated bets and live to tell about it. It is also important to know that they can “afford” to be wrong – you can’t.

Just like the glutton gorging on a delicious meal – it feels good until it doesn’t, and the damage is often irreversible. History is replete with tales of individuals who had all their money invested in company stock, companies like Enron, Worldcom, Global Crossing; etc. all had huge, fabulous runs and disastrous endings.

Concentrated bets are a great way to make a lot of money in the markets as long as you are “right.” The problem with making concentrated bets is the ability to repeat success. More often than not individuals who try simply wind up broke.


Heed Thy Warnings – the path to redemption is rife with temptation

Regardless of how many times I discuss these issues, quote successful investors, or warn of the dangers – the response from both individuals and investment professionals is always the same.

“I am a long-term, fundamental value, investor. So these rules don’t apply to me.”

No, you’re not. Yes, they do.

Individuals are long term investors only as long as the markets are rising. Despite endless warnings, repeated suggestions, and outright recommendations – getting investors to sell, take profits and manage portfolio risks go unheeded.

Unfortunately, by the time the fear, desperation and panic stages are reached, it is far too late to act, and I will only be able to say that I warned you.
