Using Sentiment Analysis as a Global Macro Investor

Forex Killer Autopilot - Why You Will Want It?
By Atlas Fountain

Sentiment analysis is typically used to determine when the crowd is wrong. Yes, that means that sentiment indicators help to determine tops and bottoms. Even if you don't trade right with them, they are useful to determine the overall risk in the market.

As with trend tools for both long and shorter terms time frames there are long and short term indicators. Tools such as the VIX, Investors Intelligence poll data, and the put/call ratio all help to better gauge important turning points.

So how do we use these tools? The put/call ratio is put together by dividing the total put volume by the total call volume. When the reading hits an extreme high level it is typically calling a bottom and when it is extremely low we are usually closer to a top. Again while you can trade directly off this info it is also useful as a risk gauge.

The VIX or volatility index is another often used sentiment indicator. The VIX measures the implied volatility of the SP500 index. Yes, using the VIX and the put/call ratios indicates that option traders are usually very wrong at turning points. Anyways the VIX basically is forecasting how much the market will move in percentage terms over the next thirty days. It is expressed as an annualized amount. A VIX reading of thirty implies that the market should move thirty percent over the next twelve months.

Usually the higher the VIX reading the more bullish the signal while the lower the number the more bearish things are. Remember that while sentiment indicators can help you find tops and bottoms they are even better suited for gauging the overall risk in the market. When investors are complacent risk is high and when they are scared risk is lower. It may sound counter intuitive but that is the way it works.

Another widely used sentiment indicator are the different investor polls. The longest running poll is the Investors Intelligence polls which have been continuously put out since the sixties.

Essentially sentiment indicators are useful to gauge the wrong way crowd. At extremes sentiment data can help you to find potential turning points in the market. And more importantly they can help you find hidden risks.

If you don't use it then you should. Sentiment data is some of the most useful and yet under utilized information available to investors. If you can find what no one is looking at you can make a lot of money when the tide turns. - 21511
