'Honey, what happened
to our retirement savings?'
If you're a man, your partner may have asked you this at
some point in the past few years.
'Hmmm, I'm not sure
what you mean?' you may evasively answer.
(The truth is, you're very aware that you invested too much in that
awesome small cap tech stock. Sure it's
down 50% since you bought in, but it is such a GREAT story, it HAS to work out.)
She persists, 'I mean,
how come the account has less money than last year? The market was up this year.'
Now if you're like most men, you want to please your wife
(and yourself). And you probably believe
what you say next: 'Um, well, I invested in CyberNanoTech and they had a bit of a setback
this year because of the FDA, but their long term prospects are amazing, everyone
says so, so I’m holding tight.'
'What is CyberMamoSpec?'
'Well, Joey at the
Club was saying they have this world changing….'
'Honey, what does Joey
know about investing, isn’t he an orthodontist?'
This is why men need wives, to pop their unreality bubbles.
It's at this point in the conversation that his wife may pick
up the phone to call a financial advisor.
And if all goes according to her plan, which is likely, their financial relationship
dynamics will become the domain of a financial advisor, which is another story
(and one I often speak to advisors about).
The above parable is an amalgam of stories I've heard from most of my male friends. As investing sterotypes go, women tend to be
more prudent and men the risk-takers. As
we'll see in this letter, the type of risk-taking men do often doesn't work out
well, especially when the men involved are amateur investors (which, despite
their winning personal assessments, most men are).
After we review of the mistakes that amateur investor men
(and women) predominantly make, we’ll look at the research behind that. Then we'll look at evidence of the role of
women in keeping public debt levels low, but also in driving firm valuations
lower. We also consider a report on the
sensitivity of female risk taking to the menstrual cycle. In conclusion we'll integrate the various
findings to see if there are any lessons for Wall Street and our society.
Gender and
Personality
Note: if you
haven't already, please take one of our free online personality
tests before reading on. You'll be in good company, over 20,000 people
have taken at least one of our tests.
In our Trader Personality Test results we see that women traders do not differ
substantially from men in terms of performance and volatility. Professional traders – both men and women –
must stay disciplined and with proper risk management in order to survive in
the business. Good discipline is a prerequisite
to successful trading.
Among people who have taken our Investor's Personality Test,
we see a different phenomenon – women vastly
outperforming men. Our Trader's and
Investor’s Personality Tests are differentiated by the average length of
holding time for positions – in the case of investors, 3 months or longer. For investors we see that gender is the most
powerful explanatory variable (after experience) in dictating market returns.
In this study we
examined investors who took our Investor's Personality Test from 2005-2010. After removing those with less than five years
experience, from countries without developed financial markets, those who gave
repetitive answers, and those beyond the age bounds 25-80 years old we had
2,600 results left. Follow this link to
take the test if you haven’t already.
Nineteen percent (19%) of the final sample were women. All test-takers had reported their largest historical drawdown and their past
five years investing returns.
Women reported much
higher five year returns than men.
Further, women reported much lower average lifetime drawdowns. Women risked less than men yet were more
profitable according to these results.
In order to
understand how women’s profits were so much greater, we looked at gender
differences in the individual bias questions in our tests. In general women reported being more
self-disciplined, grounded, and emotionally aware.
Men were more likely to report:
1.
Vengeance: Taking revenge on others.
2.
Overconfidence: A higher rating of their own investing skills
(unjustified by reported returns).
3.
Cutting Winners Short: Selling winning investments quickly (a.k.a., seeking
pride),
4.
Feeling Relaxed: Men report experiencing less stress than
women.
When you think about
it, these responses could be a bit problematic.
Bringing ego into investing by taking revenge on markets or other
traders or seeking pride through successful trading leads is far from the
rational analysis preferred by successful investors.
To be clear about
the limitations of the simple study we did, there is self-report bias in our
sample, in which people rate themselves based on their opinions. Based on cultural and perhaps competitive
pressures, men are more likely to exaggerate their risk tolerance. This study
shows that women do take less investment risk than men. At the same time women also under-report their
risk tolerance. To look into others' research on gender-specific investing behavior, we turn to a classic study.
Reseacher's Corner:
Boys Will Be Boys
Our performance results
– showing men outperforming women - are congruent with those reported by Brad
Barber and Terry Odean at the University of California at Berkeley. In a study
of 35,000 brokerage accounts between 1991 and 1997. The authors found that women had 45% less
portfolio turnover and 1.4% greater average annual returns versus male
investors. To be clear, both men and women underperformed
the stock index, but men underperformed more.
John Coates, whose work we profiled last
week, cites evidence that women change their risk taking to be more like
that of men when given testosterone. Coates
speculates that bringing more women onto the trading floor may improve returns:
[T]here are grounds for thinking that women may
be less ‘hormonally reactive’ when it comes to financial risk-taking. For
example, women have only 5–10% of the circulating levels of testosterone of
men, and they have not been exposed to the same organizing effects of pre-natal
androgens. Furthermore, some studies have found that women's HPA axes are less
reactive to stressors stemming from a competitive situation (Stroud et al.
2002). Their greater presence in the ranks of money managers may therefore help
dampen hormonal swings in the market. (Coates,
2010)
In a blog
post, Brad Barber (co-author of the study above) indicates that women tend
to be more focused on planning and wealth preservation while men are more competitive
and focused on growing capital.
As in the above, there are general conclusions to be drawn
from research about female traders and investors, but as we dive deeper into
the specifics of how men and women are affected by their biology and how they perform
in leadership groups, the plot thickens.
Women on Wall Street
The question remains, if women are such good long-term
financial decision makers, why are so few women in top investment positions? The answer to this question is not clear,
although hypotheses are many. Some have
hypothesized that there are some additional factors at play among the very
elite in the field (as Larry Summers famously did regarding women and math,
precipitating his removal from the presidency of Harvard). Others believe that many women don’t find the
political game of rising to the top of an investment firm as rewarding as men
typically do. While ego and pride appear
to disproportionately hurt men’s investment performance, perhaps these same
factors help men succeed in competitive business environments (where their
performance cannot easily be judged quantitatively).
While there are no easy answers for Wall Street leadership
positions, we do see that greater female presence in government leadership correlates
with the financial health of a country.
Women in Government
Given the above findings – that men enjoy revenge (and it
correlates with lower investment returns), that men think they are better
investors than they actually are, and that men are more likely to take
catastrophic financial risks – it would make sense that parliaments with a
higher proportion of men would experience more gridlock, higher debt, and a
worse investment track record.
In order to study this hypothesis, I first selected 18 long-term developed
countries including western European democracies, the USA, Canada, Australia,
and Japan.

Using data on the percentage of parliamentarians who are women from
this list, I selected out 18
Western democracies. Then using list of
national public debt to GDP from Wikipedia, I ran a simple correlation. It turns out that the more women in parliament,
the lower the national debt to GDP ratio (R=0.7). When the two outliers are removed (e.g.,
Japan), the correlation remains 0.7. Perhaps
men are taking more short term financial risks, while women are perhaps modulating the risk taking and keeping resources
secure for future generations.
It wouldn’t surprise me if the male propensity to ego-involvement,
seeking pride, feeling less stress despite high risks, testosterone-driven
competition, and greater risk taking are behind the U.S. fiscal cliff
debacle. Perhaps the solution is to
bring more women into the U.S. Congress.
But that said, I’m no fan of mandates, and my inclination to avoid
mandates is backed up by global evidence from corporate governance ratios.
Mandate
Femininity?
Is the answer to men's poor performance to mandate more women
in government and investment leadership positions? The preliminary evidence indicates that
mandates (at least for Boards of Directors) are a bad idea. Studies on Norwegian
firms, U.S.
firms, and Indonesian
firms found that increased female representation on the board of directors decreased long term company value.
Another interesting aspect of women's role in investing
decisions regards unstable risk taking.
The menstrual cycle appears to change how women deal with risky
situations. While men may be more
hormonally reactive to specific external events and competitive pressures,
women have an internal hormonal cycle that significantly alters their
risk-taking and emotional state. Phases
of the menstrual cycle correlate with different risk taking in this study
and this
one but not this one. The differences that are found may be traced
to both the phase of the menstrual cycle and the resultant hormone-modulated neural activity in the brain.
So while mandating more women in certain positions seems
like a good idea, there is a lot we don't understand.
More Sugar?
So far we've seen that women have higher overall investment
returns and take lower overall risk. The
higher performance of women versus men appears to be due to enhanced emotional self-awareness
and less ego involvement in investing (less
cutting winner short - seeking pride – and less revenge-trading). Further, we see that Western countries with more
women in parliaments have lower public debt to GDP and appear to think longer
term about the nation's finances. But
the evidence in favor of more women in financial industry leadership is not conclusive.
We also see that bringing more women into corporate
governance reduces firm returns (a global phenomenon). Additionally, women are more susceptible to
the effects of hormonal shifts during their menstrual cycle – those endogenous hormonal
shifts significantly alter women’s risk preferences and risk taking. Given all of the above information, when
asked if women should be more represented in Wall Street leadership positions, the
conclusion has to be an anti-climactic cop-out … it's not clear.
Sentiment Trading
Trading recap from last week: Our one-week
buy on DryShips (DRYS) was up 1%, and the one-week short on InterOil Corp (IOC)
also made money, as that stock was down 6.5%. Our medium term picks of RIMM and KOL (Coal
industry) are moving along, with RIMM now up more than 20% from our
recommendation, but KOL is still floundering.
Week ahead: We
have two short term calls: A short on
Nokia (NOK)
for the next week. Nokia has run up far, fast, but it appears the short term
exuberance has run ahead of itself. We’re
seeing a one week buy on Diamond Foods (DMND)
which had a stock price plummet and is now buffeted by extreme negativity in
social media.
While short-term strategies are the easiest to find with
sentiment data, we’d really prefer to offer longer term strategies, and we
think we’ve found some. We’re putting them
online soon, and I’ll be discussing more macro calls (and fewer short term
ones) in later newsletters.
