It's the best month of the year for the dollar index

The US dollar had a terrible start to November as it was beaten up across the board on November 1 with particular weakness against AUD, NZD and GBP.

But the dollar bulls might yet have the last laugh. Or at least they will if the recent seasonal patterns hold up.

Over the past decade, November has been the best month for the US dollar index, averaging a climb of 1.46% in that time and climbing in 8 of the past 10 years.

The dollar is particularly strong in November against the euro, New Zealand dollar, Swiss franc and yen.
