The Sectors are defensive.
The Styles are neutral.
My guess is that money is moving between sectors instead of
running for the hills – but that’s just a guess. My models only show WHERE to invest, not
WHETHER to invest. These are not timing
models.
As for timing models…
The Kirkpatrick and Dahlquist book, Technical Analysis, probes each traditional method used to
measure price and volume and finds one resounding conclusion over and over
again: each one stopped working after the turn of this century.
The work is encyclopedic, fascinating, and hopeless.
In other words, by the time everyone realizes something
works, it will stop working.
In some cases a time limit is implied in the observation
itself. For instance:
On a purely price basis, the S&P continues to stay on
track, with both long term and short term regression forecasts intersecting at
2000 before the end of the year.
As would any “technical” observation, it works until it
doesn’t. But in this case there is a
time limit – the forward regressions terminate at their intersection point in
November 2014. After that the two
targets diverge and volatility should increase as imagined inevitability gives
way to realistic uncertainty.
But the problem here isn’t just the time limit. Rising wedges (as in this regression graph)
often fail before their intersection point just because that point is too
obvious. The trade itself is crowded.
It is precisely this aspect of “crowded” trades that can
affect popular quant based formulas.
The Greenblatt formula is a good case in point. In my own observations, Greenblatt’s one-year
holding period substantially underperforms three-month and three-year holding
periods. The reason? Everyone who uses it is trying to hold for
one year and that trade is too crowded.
Does that mean Greenblatt doesn’t work? No. It
just means that it doesn’t work as
advertised.
NOTHING works as advertised, because your competition has
read the same advertisements you have.
I don’t advertise the guts of my own model. But even so I’m comforted by the fact that in
the few cases I’ve tried to describe the model, my audience shook their heads
and said it didn’t make any sense.
One hedge fund manager told me, “That’s weird.” I replied, “It’s weird, but it works.” (I
actually have solid theoretical analysis for why my “weird” model works, but I
didn’t give that to the gentleman).
I was both disappointed and encouraged. I was disappointed that I wouldn’t be doing
business with him, but I was encouraged that he wouldn’t try to duplicate my
own work.
So my weird model works – for now. How LONG it works into the future depends on
how long it takes for other folks to duplicate it, but I’ve built into the
model some self-adaptive features that should keep it away from my potential
competition for as long as possible.
Another reason that formulas fail is that the market itself
changes in character. There is a core of human nature within the market that
falls prey to successful strategies, but those strategies compete against each
other as well. Mean reversion investors
sell to momentum traders, and both hope to scalp the hapless retail short
trades (on the mean reversion end) and the gullible long trades (on the
momentum end). Humans scalp dollars from
other humans, and black box algorithms slice off an infinite amount of pennies
in between.
Thus, the average retail trader underperforms the market;
and the average mutual fund underperforms the market too.
Index investing, therefore, will become more popular over
time.
So where does that leave us?
Pretty much the same as always: invest in companies instead
of stocks. A stock is worth the value of
its company’s future cash flows. That’s
all stocks have ever been worth. And
that’s all that stocks will ever be worth.
Any other movement is random noise. Sometimes a stock will go up because
a company is ruthlessly selling assets and laying off workers, and even
hopelessly outdated business models can bounce when such trimming occurs. These
things affect future cash flows in the short term, but cannot sustain a company
for the long term. I remember one year
that Value Line gave Earthlink a good projection, not because dial up had any
hope of survival, but because they were slashing their work force faster than
their business was shrinking and the stock might bounce.
It has indeed bounced, many times, on the long road down.
In the end you have to invest into companies that you can
hold for years if you need to. Even with
my own trading models I have metrics in place to track stocks AFTER I sell
them, in order to know how long to hold them if something pulls me away from
the market in the near term.
You have to be able to walk away.
It’s summer. Go to
the beach. Take a walk.
That’s what HUMANS need to do. Black box algorithms are reading the news
now, trying to anticipate what people are going to do mid-day.
People have no business looking at the market mid-day. We have little business looking at it
mid-week. If you want to stop getting
chewed up by high powered algorithms, less is more.
My grandfather picked stocks that would outperform for a
decade. When he passed away my
grandmother left his choices in place – against the urging of her advisors.
My grandmother was right, because my grandfather was
right. For the rest of her life her
stocks outperformed the broad market.
When the world thinks short term, think long term.
Even if you trade short term, think long term.
Long term isn’t based on timing or momentum.
Long term is based on value.
Tim
