Citigroup Panic/Euphoria Model: Another Useless Sentiment Indicator at Trader’s Narrative

The worst thing an indicator can do is not to be consistently wrong but to have no edge whatsoever. This is because if it is consistently wrong or almost always wrong, then it can be used as a contrarian indicator. Jim Cramer would be a good example. If on the other hand the indicator is more or less right on the money, then it is a leading indicator. A good example would be the OEX options market.

The TickerSense blogger sentiment poll is useless as a sentiment indicator because it has no edge, it is just random data. Noise. To this useless sentiment indicator, we can add another one: Citigroup’s Panic/Euphoria Model.

This is an proprietary aggregate measure of sentiment from the quants at Citigroup and is published weekly by Barron’s in their sentiment section. If anyone had any doubts as to the value of this indicator from Citigroup, this most recent market upheaval has given them a definitive answer.

As we suffered one of the sharpest drops in stock market history, as volatility spiked to record highs, as sentiment measured by traditional investor surveys reached epic pessimism, as breadth redlined, the Citigroup’s Panic/Euphoria Model yawned and continued napping:

I’m not sure what goes into the calculation of this number and frankly, I don’t care. Whatever recipe Citigroup Investment Research is using, it is garbage. What I can’t understand is how anyone can continue to come in in the mornings and crunch numbers for this indicator when it is completely separate from reality. Why is a reputable publication like Barron’s legitimizing this drivel by disseminating it every week?

Tweaking Garbage
Although the make up of the indicator is secret, there are some hints that Citigroup has tweaked it in. You can see that in the chart below (from April 28th 2008), the low in March 2008 does not coincide exactly with the same trough in the most recent iteration of the graph above. The low in March was deeper (more “panicky”) and it registered closer to the end of the month while in the most recent data, it is shallower and occurs mid-month.

The problem with tweaking garbage is that even if Citigroup corrects it, the data won’t be historically comparable. Just like TickerSense, the best thing to do is to acknowledge reality and discontinue it.

    ‘Yet another sentiment index’
    Please visit to check out yet another market sentiment index called the ’sentinelling index’. I would be very interested to read what you have to say about it.

    Thanks Tasquatch, I found and read your blog a while back but can’t really understand what you are measuring or how you measure it. Is it proprietary?
    ps love the disclaimer on your sidebar ;)

    Hi Babak,
    Yes, it is proprietory. The sentiments are currently extracted using daily price data and hence tend to be more precise and objective as compared to fuzzy and subjective opinion polls. It also enables one to measure not only market sentiments but also stock sentiments. The red-line depicts the % bullish-sentiments and the blue-line depicts the % bearish-sentiments. I find the ’sentinelling index’ is able to reflect the market and stock sentiments quite realistically. The current financial crisis is fully reflected by the SI.

    Please revist the above mentioned blog and the contents of the sidebar. Do feel free to ask (by leaving a comment on my blog)for clarifications on any areas you do not understand. I looking forward to your visit.
    ps: youur ‘disclaimer’ was too perfect to ignore. I hope you do not mind…:)
