Trade Like A Quant

Sometimes dubbed the rocket scientists of Wall Street the meaning of quantitative analysts often takes on a broad meaning.  Quant is a fairly broad term honestly, but roughly means someone who takes an extremely mathematical approach to the markets.  While some quants use Einstein level math there are some practical lessons you can take away to use in your own portfolio.

More than anything quantitative analysts apply a rigid rules based approach to the markets.  They have specific buy and sell signals that they adhere to religiously and consistently.  This is where their great returns come from(if their algorithms are correct).  While some get blamed for things like the flash crash where the DOW dropped 9% in minutes it would be wrong to say that it was the strangest thing to ever happen in market history.  A signal for a quant could be something as simple as the 200 day moving average or as complex as analyzing S&P 500 futures contracts volume and expiration and placing an order nanoseconds before the futures expire and pocketing the spread, which is the high frequency trading world.

So how can you apply this? Well a buy and hold strategy sounds great in theory, but its harder to stick to in practice.  Sure its easy to say when the market has not had a down year since 2008, but it would have been really hard to hold onto your portfolio is 2008 when the US equity market shed about 40%.  If you haven’t experienced a massive drawdown like that imagine draining half of your savings.

So if you are someone who can’t weather massive drawdowns, and we don’t blame you if that is the case, consider taking a rules based approach.  It is great to have an investment plan that you can stick to and might even help you sleep better at night.  Here is a simple rule to get you to start thinking about what you might want to do:

Apply a short, medium, and long term moving average to your portfolio.  When conducting your rebalancing, best done once a year for tax benefits, tilt most towards the assets in upward trend above the moving averages, more towards the one that are not trending as strongly above one or two of the moving averages, and least towards those in a downtrend under the moving averages.

Note: This can be considered a trend following approach and is a popular investment style that may or may not suit you.  Over time strategies go in an out of favor so its often wise to pick a strategy that you understand and believe in and stick with it over the long term.

Building wealth takes strong discipline and taking your emotions out of investing by applying rules to a strategy that works can often help mitigate bad decisions.

Main Street’s Edge

One thing that new investors, myself including, usually grapple with is the belief that investing is a zero sum game.  There is a winner and loser on every end of a trade.  Furthermore, another hesitation plaguing retail investors is the belief that Wall Street has the edge with their superior research and execution ability.

The bad news is Main Street is completely right.  In the short term, trading is a zero sum game, there will be a winner and loser on either side of a trade.  This is especially true when we look at the options and futures markets.  If that’s not bad enough, fund managers have armies of PhDs at their disposal to conduct cutting edge research and legions of engineers designing computer systems to place trades in nano seconds essentially cutting the line in the execution queue.


If you’re still reading good!  There may be hope for Main Street yet.  First, I would challenge you to think long term.  Investing education is fundamentally flawed in the sense that most people learn that the best way to invest is to pay close attention to a handful of hand selected stocks.  This causes us to over trade and exposes us to a lot of unnecessary risk.  If we look at the major indices we see a steady increase over time.  This makes sense because as the economy expands due to things like population growth which increases the labor force, technological advances which makes workers more productive, etc.  All of this steadily increases corporate earnings which is reflected in the steady increasing of major indices like the S&P 500.

In the past 90 years an investor could expect a 10% return annually on average from the S&P 500, though don’t take this at face value because annual returns fluctuate widely.  A modern investor could capture this utilizing the ETF SPY or the Vanguard 500 fund which have both minimal tracking error and costs.  You would continue to collect dividends, eliminate single company risk, and significantly outpace inflation in the long term all at a cost of less than 20 basis points per year.

So why doesn’t Wall Street just buy and hold if it’s that easy?  If you look at a hedge fund’s fee structure you may see that most charge 2 and 20.  2% on your total account value and 20% on returns.  The truth is Wall Street relies on investor money to pour in to make money.  To attract that money they have to outperform the benchmark S&P 500 and unfortunately few managers can consistently outperform ultimately resulting in being canned by their investors.  This is not to say that all money managers don’t deserve their paychecks.  In fact, there are countless managers who provide amazing strategies that outperform with low correlation to the equity markets you just have to do your due diligence to find them.

The edge that the small investor has is that they can buy and hold over long periods without having to answer to stakeholders.  While money managers were begging people to stay in 2008 the average investor could smile and pour more money into their IRAs buying US equities at huge discounts.

“Our favorite holding period is forever” -Warren Buffet

A prime example of this is Warren Buffet.  AQR published a paper on how he generates his alpha, a measure of market outperformance.  They concluded that Buffet’s philosophy of buying and holding great companies trading at fair prices outperforms because of two main factors. First, Buffet believes in his strategy as his market holding period is “forever.”  If you’re still not convinced, Buffet has seen his holdings decline by over 50% on two separate occasions in his career.  His sheer ability to sit through massive drawdowns is a big reason he is regarded as the greatest investor of all time.  Second, he is able to strategically apply leverage, a concept we’ll discuss in articles to come.

So there you have it.  As a retail investor you have the luxury of not answering to stakeholders who want consistent outperformance and are less tolerant of drawdowns which every portfolio is subject to.  Of course you have to have the discipline to sit through them, but being able to accept market returns over long periods of time is usually all the edge an investor needs to build wealth.

A Random Walk Down Wall Street

Our Rating: 7/10

A Random Walk Down Wall Street by Burton Malkiel

A classic and essential reading for those seeking to further educate themselves on the financial markets. This book reads like an informal textbook that will teach concepts, provide real world examples with accompanying charts, and keep readers entertained with stories and anecdotes.

The author is a Princeton economist who is a champion of the efficient market theory. He begins with a brief history of financial bubbles that most people will think too crazy to be true. But we here at The Modern Piggy Bank looked more into these and were shocked at how irrational crowds can be and how strong mob mentality is.

Next, he shows how the biggest money managers on the street invest. Lastly, the information is wrapped up with practical ways for the average person to invest their money for the long run.

“Forecasts are difficult to make- particularly those about the future”

Malkiel argues that most money managers charge high fees for strategies that 1) not guaranteed to beat the market and 2) are strategies most investors can employ for a significantly lower cost. Malkiel’s main theory is that individual returns are random at best so no one can consistently beat the market.

We enjoyed this book as it shows, with real data, that money managers might not be the geniuses the media portrays them to be. However, our thoughts diverge in that to truly believe in Random Walk you must also believe that investors like Warren Buffet and Ray Dalio, who have consistently beat the market over the long term, don’t actually have an edge.
