Quantitative Investing for the Modern Portfolio Manager 9/20/14

MTA (Market Technicians Association) had an outstanding all day event on 9/20/14 in Charlotte, NC. Top speakers included Meb Faber, Perry Kaufman, Mathew Verdouw and Charlotte’s own Carson Dahlberg.  I rate the event an A+. I will do my best to summarize this event but realize I could not do it justice in this short blog space.

Meb Faber, whose work in “Ivy Portfolio” was outstanding, kicked off the presentations. Meb’s talk was on “Global Value. How to Spot Bubbles, Avoid Crashes and Earn Big Returns”. Robert Shiller in his book “Irrational exuberance”, the term made famous by Alan Greenspan, defines CAPE as Cyclically average inflation-Adjusted Price Earnings ratio over the last 10 years. Meb says “Valuation is all about avoiding buying the expensive as well as buying the cheap. Through Cambria funds Meb puts his money where his mouth is… and invests using the notion that where the blood is also offers the real opportunity to make good returns.
Blood   CAPE <7         1 yr return 31 %  3yr return 18 %   5yr return 21 %
Bubble CAPE>45        1 yr return -9 %  3yr return -4 %   5yr return  -1 %      
Using CAPE values for various countries, the best investing opportunities are Greece, Russia, Ireland, Hungary, Argentina and the worst places for investment are with the highest CAPE such as Malaysia, Colombia, Philippines, USA, and Indonesia…. However he notes that the current CAPE for US is at 26.6, and that there is still room for higher valuations and growth.
How do you identify a Bubble? “When my Mom e-mails me….” And then Meb gets serious and says CAPE of  5 close your eyes and put your money in, CAPE of 30 consider a Yellow flashing light and 40 as Red.

Perry Kaufman spoke about “Risk Management using a Relative Value Arbitrage Trading Strategy” and describes this as one of the 3 trading strategies he uses to trade his own money. Perry noted that “it is more important to trade diversified strategies than markets”. He also uses a trend following strategy as used by 60+% of funds and also a pattern recognition strategy. Arbitrage – buy the cheap and sell the more expensive stock, fund or similar market involves finding two stocks or ETF’s that have a correlation between 0.3 to 0.8, and use a ratio of the two to find overbought and oversold levels. Stocks such as Ford/GM or Amazon/Wal-Mart are examples. He uses stochastics and an indicator referred to as Stress indicator to determine Oversold OS or Overbought OB. Oversold means price has dropped over the last period of time. Ford is OS relative to GM when the Stress indicator is below 10. We use this as an entry to buy F. Exit when stress indicator greater than 50 as it is neutral then.
He mentioned his book “Alpha Trading” and how he took the concepts further. I have known of Perry since I had a copy of his adaptive moving average indicator many years back and highly respect his work. I certainly feel I cannot do justice to him in this short blog but was intrigued by his arbitrage method. He mentioned how the market is biased towards the upside, and that the hedge usually loses money. Still, he likes to place a hedge when the market trends down cutting his losses by half. He admits to losing money in bear markets as it is very difficult to make money shorting.
Perry says “I hate stop losses” as they fight the system. Trend following systems require one or two large big moves to make all the money and with stop losses that can be taken away. He uses a 15% price stop from point of entry just as an emergency.
My own past work using Metastock and back testing many stocks and systems shows that stop losses degrade performance and that only very wide stop losses are of any use. I think Perry is right on.
He mentioned arbitraging stocks such as AMZN against QQQ. He would only take the long side of the AMZN trade based on the low OS value of the stress indicator; and add the hedge only if the trend is downwards. Otherwise he bets on the fact that markets are biased towards the long side. He determines his trend based on 30, 60 and 120 day moving averages. He typically likes to place a 1/6 hedge when price drops below each of these moving averages.

Mathew Verdouw’s talk on “Portfolio Optimization using Relative Rotation Graphs RRG’s” was the last presentation of the day and certainly equally interesting. The power of RRG’s is in normalization. RRG was developed by Julius de Kempenaer. Using 4 quadrants one could take the various sectors of the S&P and see if each sector is in which quadrant - leading, weakening, lagging or improving. Looking at the quadrant and finding sectors that have a hook and are moving from a lower lagging or weakening quadrant to the higher improving and leading quadrants gives us which sectors we should focus on. Then we can pick the stocks in that sector using the same RRG methodology and determine the largest opportunity.



Following Meb and Perry’s logic; Mathew points out that the better opportunities are with stocks that have pulled back to the lower quadrants. RRG gives a great visual tool to see the behavior of the stock and when to get in.
A quick Yahoo search on my smart phone yielded that you can get RRG’s from Bloomberg, Stockcharts.com and certainly also from Mathew at

Mathew has moved from Australia to Charlotte, NC and is working with some larger corporations who are incorporating RRG graphs. This is a business he started about 17-18 years back and my hats off to him and the others who made Saturday a memorable event for me….I apologize for not giving Carson the blog space he deserves but this blog is long enough.


By the way my SPY chart finally popped in a buy signal… and using my Ivy portfolio ETfs, all are down exception of SPY and VTI Vanguard Total Stock Index.
