I owe someone at the Fed a beer for all the recent additions at http://research.stlouisfed.org/fred2/.  I have covered some in Spreads and Stress and Gifts from BAC ML and the Federal Reserve.  The newest addition 8 Chicago Fed Indexes Added to FRED contains a nice weekly series on US National Financial Conditions that I’m sure we can use.

How does the S&P 500 look against the Chicago Fed Adjusted National Financial Conditions (ANFCI) index?  I did not look at the nonadjusted FCI, but I’m sure it offers potentially useful information also.

Can we build a silly system with the S&P 500 and ANFCI?  THIS IS MERELY AN ILLUSTRATION AND DOES NOT CONSTITUTE FINANCIAL ADVICE.  YOUR GAINS AND LOSSES ARE YOUR OWN RESPONSIBILITY.

Nothing particularly special system-wise, but 1998-2004 is a very abnormal circumstance.

R code:

#explore how SP500 behaves in different ranges of Financial Conditions   require(quantmod)
require(PerformanceAnalytics)
require(ggplot2)   #get data from St. Louis Federal Reserve (FRED)
getSymbols("SP500",src="FRED") #load SP500
getSymbols("ANFCI",src="FRED") #load Adjusted Chicago Financial   #show a chart of ANFCI
chartSeries(ANFCI,theme="white",name="Adjusted National Financial Conditions (ANFCI)")   #do a little manipulation to get the data lined up on weekly basis
SP500 <- to.weekly(SP500)[,4]
ANFCI <- to.weekly(ANFCI)[,4]
#get weekly format to yyyy-mm-dd with the first day of the week
index(SP500) <- as.Date(index(SP500))
index(ANFCI) <- as.Date(index(ANFCI))   #use ceiling to get ranges for ANFCI so we can run boxlplots
ANFCI <- floor(ANFCI)
#lag ANFCI signal
ANFCI <- lag(ANFCI,k=1)   #merge sp500 returns and ANFCI
SP500_ANFCI <- na.omit(merge(ROC(SP500,n=1,type="discrete"),ANFCI))
colnames(SP500_ANFCI) <- c("SP500","ANFCI")   #convert xts to data frame for ggplot boxplot exploration
df <- as.data.frame(cbind(index(SP500_ANFCI),
coredata(SP500_ANFCI[,1:2])))
ggplot(df,aes(factor(ANFCI),SP500)) +
geom_boxplot(aes(colour = factor(ANFCI))) +

signal <- runMax(SP500_ANFCI[,2] , n=10)
#go long if Max of ANFCI over last ten weeks is 0; already lagged earlier
