    What Is a Spread LSR Alert?

    An LSR alert will fire if the most-recent $spread price is outside the boundary created by multiplying the standard deviation of the price series with the supplied "standard deviation multiplier", and then adding or subtracting the least squares regression value at the same point in time.

    The Spread Analyzer provides the customers with the ability to create 3 of these alert for each spread.

    Relative Value in Credit Risk

    I think there is a relative value opportunity in credit risk.  I typically focus on equity opportunities but I think this one has the potential to be big enough to branch out to the fixed income asset class.  My background is in equity derivatives, so I understand a little about the market's ability to price risk.  

    With long-term risk-free rates at historic lows, investors are taking on increasing amounts of credit risk without being properly compensated.  People need yield and as a result are buying lower quality credits.  This is happening all across the credit curve. Treasury investors are buying high-grade credits, and high-grade credit investors are moving towards high-yield.  Risky credits are bid up relative to less risky credits.  This presents a relative value investment opportunity to buy low-risk credits and sell high-risk credits.  The beauty of this trade is that it has the potential to be profitable in two scenarios: 

    Recession.  A recession would keep rates low, but would be a negative in particular for high-yield issuers.  Defaults would scare investors away from high-yield, and investors would move toward high-quality credits. 

    Growth.  If the economy shifts into high-gear and inflation picks up, the Fed will raise rates.  When this happens, investors will be able to achieve yield in lower-risk credits.  Investors will slowly pull money back toward investment grade bonds.   

    I like this trade because it has the potential to pay off no matter which direction the economy moves. This is the fundamental investment thesis for me in this latest spread trade.  I asked myself some key questions, prior to making the investment:

    1.  What should timing be?

    2.  What are the risks here?

    3.  What is the best vehicle to get involved in this trade?

    Timing is critical in any investment.  If you time it wrong you can be sitting on a bad trade for a long time. Even Paulson’s “$15 Billion Dollar Trade” against sub-prime mortgages was in the red before it paid off.  Here, shorting junk bonds has a high cost-of-carry (around 6% per year).  The cost of timing it wrong can be pretty high.

    Risks.  The investment is profitable in both bull and bear markets.  The biggest risk is that nothing happens in the market.  In that case I will pay the cost-of-carry for an extended period of time before my trade is profitable.

    Trading Vehicle.  This is an important question since it impacts my economics significantly.  That said, I am sure there are many vehicles to profit from this opportunity.  I don’t want to bet on specific bonds, but rather the overall market.  With my typical focus on equities, I naturally look to the ETF market.  Specifically, $LQD is an ETF that tracks the performance of the investment grade bond space. $HYG tracks high-yield.  Both are liquid iShares ETF’s with tight bid-offers.  $LQD is yielding around 3% and $HYG around 6%.  With bonds, we trade pairs using the concept of duration-neutral to insulate us from the impacts of interest rate changes.  $LQD has an average duration of 7.7 and HYG 3.9.  Therefore I choose the ratio 1 x 2.  Here is a chart of the spread 1*LQD-2*HYG. As you can see, it tends to spike higher during credit crisis times, and trend lower as rates decline.  Given that $HYG has only been trading since 2007, there is not enough history to see performance during high and low interest rate regimes.

    I am monitoring this spread to try to determine a good time to enter the trade long. I am also considering other trading vehicles.

    NutriSystem - Note to Self

    I am liking the spike I am seeing on the Nutrisystem ($NTRI) chart. There is a ton of value in this situation and the present set up reminds me oF Avon ($AVP). I wrote about Avon right here.

    There is a ton of potential energy in the SPY/NTRI spread.

    Trading With Python - Online Course to Boost Your Bottom Line

    - Update 4/17/2013. This course has started  and it is closed to new applicants.

     

    Many of you know me as a quantitative trader, blogger, and webinar host.  Some of you know that I studied Engineering at MIT.  I have worked a bit with computer programming and I certainly understand the power of computers to crunch huge amounts of data.

    In trading, there are millions of potential trades and many different ways to evaluate each trading opportunity.  Obviously this process can be improved using the data crunching power of computer programming.  Of course, the idea of learning to program can be daunting.  There is a steep learning curve associated with programming.  That is why I am excited for an upcoming course given by fellow Bigger Capital trader and programmer Jev Kuznestov.  Jev’s course is scheduled to start in April, and it will help traders learn programming as applied to quantitative trading.  I have personally worked with Jev on several occasions, and I know he is a smart, experienced programmer who knows his stuff. He is also a great trader.  I plan to attend the course to get up to speed on Python and learn from Jev’s expertise.

    The main goal of this course is to help a trader to become a quant. It will teach how to get and process incredible amounts of data, design and backtest strategies and analyze trading performance.

    The course gives you maximum impact for your invested time and money.  It focuses on practical application of programming to trading rather than theoretical computer science.  The course provides you with the best tools and practices for quantitative trading research, including functions and scripts written by expert quantitative traders.  The course will pay for itself quickly by saving you time in manual processing of data.  You will spend more time researching your strategy and implementing profitable trades.

    The course will span 4 weeks, each week will start with a screencast.  There will be required reading material plus example code (see example here)  for further study. At the end of the week there will be a live online Q&A session. 

    Course fee: $350

    Beta - Spread Trading Webinar

    On Wednesday we held a webinar to discuss the statistical arbitrage trading parameter "Beta".  We had good turnout, and a lot of you requested the replay (at the bottom of this post).  We had some great questions, and I wasn't able to answer them all during the webinar.  One of them in particular I wanted to cover here, because it was quite thoughtful and insightful.  In answering it, I thought about the many interesting ways to look at spread trading.
     
    The question was about my selection of spread.  I talked about FDX-UPS, and you can see a chart of the spread here.  This spread is not cointegrating, so the question asked why I had chosen it in a discussion of statistical arbitrage spreads.  I like that spread because the companies are so similar, and I make money trading it when it is statistically cheap or expensive.  I do not worry about the cointegration, because for me the company relationship and the fundamentals are my spring force.  I use the other statistical parameters such as zscore, half-life, and beta in my trading.  
     
    The person who asked the question suggested that the 1 year chart showed positive autocorrelation (which to me means it is trending higher).  Betting on mean reversion is fundamentally different from betting on momentum (trends).  Both views can be expressed using spreads.  There is no way to know for sure which way the spread will go in the future.  For this reason, some traders (including me) look at additional factors such as fundamentals or technicals to help predict the future performance.  
     
    What do you think of FDX-UPS?  Will it continue to trend higher, or revert back to the mean?

    Trading the Defense Stocks Spike

    Last Friday we traded a basket of defense stocks againts the XLI ETF (Industrial Select Sector). The goal is to take advantage of the spread spike displayed on the right side of the upper graph. The upper graph displays the price of 1000 * XLI minus the basket of defense stocks. 
     
    The lower graph displays the value of z-score. The last z-score recorded a value of 4.37 which is an extreme deviation away from the mean.
     
    We sold the spike!
     
    Defense stocks are trading down on an anticipation that defense spending will be cut dramatically. Gene Epstein at Barron's stated in his latest piece not to believe the hype about defense cuts
     
    We shall see if he is right or wrong. We view this trade from a purely statistical basis with time and price stops.
     
    We have posted the detailed description of the basket in the forum section of our $spread premium product. This is the first time we expose our statistical basket data to the outside world. Dear users let us know what you think. For traders who do not have premium access to our product you can look at spreads between the $XLI and stocks such as $GD, $BA, $NOC and so forth using our spread analyzer.
