This signals a major drop for the Dow

Even the biggest players can be caught out by big moves in the markets, says John C Burford. But by sticking to your trading methods and watching for sentiment, you can avoid making the same mistakes.

As you know, I rely on the weekly commitments of traders (COT) data from the US Commodity Futures Trading Commission to help me understand how the internal strength or weakness of markets is changing over time. Such information, although reported several days in arrears, adds significantly to the evidence I like to assemble to suggest a trade.

And last Friday's data certainly illustrates a key principle with futures markets that the large non-commercial sector (primarily hedge funds) are mostly trend-followers.
