How to Invest Like a Quant Fund
Thursday, September 25, 2014

Quant funds utilize computer algorithms to guide their investment strategies. These computerized methods pick securities based on quantitatively identifiable characteristics. Rather than selecting stocks with a good story (e.g., Alibaba (BABA)), they select stocks based on various fundamental or technical criteria.

Many hedge funds follow quantitative strategies. Smart beta funds also follow these strategies. Last week, Morningstar announced that it is now designating quant exchange-traded funds (ETFs) as strategic beta funds. The investment research company described these funds as those that try to improve returns or isolate a specific return relative to a benchmark, increase or decrease the level of risk relative to a benchmark, or follow non-return or risk-oriented strategies, such as equal-weight strategies.

The basic idea behind quant funds is to identify anomalies or return factors that lead to higher returns or less volatility. By giving a preference to investments with these characteristics, higher returns, less volatility or both are sought. It can be an unemotional way to invest as long as personal biases are not allowed to interfere with either the creation or the execution of the model. The better you are able to stick to the model, the more you will be able to invest like a quant fund.

Creating your own model does require a level of comfort with a good screening program such as our Stock Investor Pro and, depending on the model used, a spreadsheet. If you are unwilling or unable to do the mathematical and computer work, following a quantitatively oriented screen or buying a strategic beta fund may be the better option.

If you are comfortable with the computer aspect, you then need to be aware of what characteristics are similar and what are different. For example, dividend yield and the price-earnings ratios are both valuation indicators, whereas debt-to-equity (leverage) and relative price strength (price momentum) are different measures. You want give considerable thought to what goes into your model and whether it gives the model a tilt. There is nothing wrong with having a model that emphasizes, say, value, but you should be intentional in trying to achieve that focus.

The next step is to determine how to use the various factors to influence which stocks top your results. Your choice is to use either factor or absolute criteria. The factor approach weights each criterion (or composites of like criteria) equally and then selects the stocks with the best factor scores. This was the approach discussed by Ronen Israel, a principal at asset manager AQR Capital, at Morningstar’s ETF Conference last week. It is also the approach Jim O’Shaughnessy talked about at the 2013 AAII Investor Conference. With an absolute criteria approach, you are telling the screen to identify only those stocks meeting specified criteria (e.g., a price-to-sales ratio below 1.2) and to ignore anything outside of those boundaries.

Ronan told me after his presentation that he likes the factor approach. He believes factor models do a better job of maintaining the diversification benefits of equally weighting criteria with different attributes. If absolute criteria are used, then the model can end up being biased toward one particular investing style (e.g., value).

Absolute criteria works better when you want more a style-plus strategy, such as value with a momentum tilt. This would ensure you don’t buy stocks above a certain valuation limit, while still taking advantage of momentum characteristics.

Once you decide on the appropriate approach to follow, you have to pick the specific criteria by which to identify stocks. There is no single right answer as to what to include. O’Shaughnessy’s model uses value, financial strength and earnings quality composites. Israel used an example of value, momentum and defensive (earnings quality). Research Affiliates’ RAFI Index looks at book value, cash flow, sales, and gross dividends. The key for you is to seek factors that complement each other and add benefits to the strategy.

I think it is helpful to take a step back at this point and ask whether your approach is logical. Think about what type of stocks your strategy is designed to identify. Additionally, take a look at the criteria in your model. Are they factors proven to individually lead to higher returns or reduce risk in the past? What you want to watch out for are anomalies that do not have a logical reason for working. (This is a common problem with backtesting; you may end up with odd combinations of criteria with good historical returns for no particular reason.)

Your final step is execution. You need to determine your sell rules, whether you will rebalance your holdings, and if so what amount to use to add new holdings. Keep in mind the two advantages you have over all quant funds: scale (you can buy less frequently traded stocks) and no requirement to report performance. The latter is a big advantage because all strategies will underperform for periods of time, even when their long-term returns are very impressive.

The Week Ahead

I accidently forgot to mention in last week’s email that Rosh Hashanah is this week. The Jewish holiday started last night and goes until tomorrow evening. L’Shana Tova to those who are celebrating it.

Only four members of the S&P 500 are scheduled to report earnings: Cintas Corp. (CTAS) on Monday, Walgreen Company (WAG) on Tuesday and Constellation Brands (STZ) and McCormick & Company (MKC) on Thursday.

The economic calendar has August personal spending and income and the August pending home sales being released on Monday. Tuesday will feature the July S&P Case-Shiller home price index, the September Chicago PMI and the Conference Board’s September consumer confidence survey. The September ISM manufacturing index, the September ADP employment index, the September PMI index and August construction spending will be released on Wednesday. Thursday will feature August factory orders. The September employment report (including the unemployment rate and the change in nonfarm payrolls), August international trade and the September ISM non-manufacturing index, will be released on Friday.

Two Federal Reserve officials will speak: Chicago president Charles Evans on Monday and Governor Jerome Powell on Tuesday.

AAII Sentiment Survey

Optimism among individual investors about the short-term direction of the stock market remained above its long-term average for the seventh consecutive week, according to the latest AAII Sentiment Survey. Although above the long-term average, bullish sentiment fell slightly compared to last week. Neutral sentiment also declined this week, while pessimism rose.

Bullish sentiment, expectations that stock prices will rise over the next six months, declined 0.4 percentage points to 41.8%. This week now ties the seven-week stretch that the bullish sentiment stayed above its historical average of 39% between November 28, 2013, and January 9, 2014. The next record will be surpassing the 14-week stretch between December 29, 2011, and March 29, 2012.

Neutral sentiment, expectations that stock prices will stay essentially unchanged over the next six months, declined 4.9 percentage points to 29.9%. This puts the neutral sentiment below its historical average of 30.5%, breaking the three-week streak.

Bearish sentiment, expectations that stock prices will fall over the next six months, rose 5.2 percentage points to 28.2%. This increase pushes the bearish sentiment reading closer to its historical average of 30.5%. Bearish sentiment last passed its historical average level on August 7, 2014.

Keeping many individual investors optimistic about the short-term direction of stock prices is the S&P 500’s overall upward momentum, earnings growth, sustained economic expansion and the Federal Reserve’s tapering of bond purchases. Causing other AAII members to be pessimistic are prevailing valuations, the failure of the S&P 500 to set new highs, events in the Middle East and Ukraine, the pace of economic growth and Washington politics.

This week’s special question asked AAII members for their opinion about the current state of the job market. About 5% described conditions as improving. Slightly more than 24% of members said the labor market is improving, but the pace of growth remains too slow. At the other end of the spectrum, 24% said the job market is still weak.

Common themes among respondents were wages and job skills. Many members thought too many entry-level or lower-skill jobs were being filled and too few higher paying jobs were being created. Several members also discussed skills, either in terms of workers not having enough skills or being overqualified, or in terms of companies not providing adequate training.

Here is a sampling of the responses:

  • “Improving and likely to continue. However, there are a lot of low-paying jobs out there.”
  • “Much of the current unemployment is due to a lack of skills.”
  • “Stagnant, woeful and lacking for all but the most menial jobs.”
  • “Stronger, but wages are too low and there aren’t enough good-paying jobs.”
  • “Many workers are being forced to take jobs below their qualifications.”

This week’s AAII Sentiment Survey results:

  • Bullish: 41.8%, down 0.4 percentage points
  • Neutral: 29.9%, down 4.9 percentage points
