Winning streaks are in the news now that the World Series is at hand.

The Colorado Rockies put together an amazing winning sequence that carried them through the National League playoffs while the Boston Red Sox's ticket to the Series was a do-or-die three-game winning streak against the Cleveland Indians.

With the 5-year-old bull market showing some major signs of fatigue, investors might be interested in learning about some exchange-traded funds that that are riding winning streaks.

It turns out that none of the 19 ETFs with sufficient track history will be able to boast a 10-year winning streak at the end of the year. The same holds true for eight-year streaks for the 33 ETFs in existence at the end of 1999.

A search of TheStreet.com Ratings database for ETFs with positive returns over the past five calendar years in addition to the first three calendar quarters of 2007 produced only two hits, which are summarized in the accompanying table below.

The

iShares MSCI South Korea Index Fund

(EWY) - Get Report

has produced positive results for its holders every complete calendar year since its inception in May of 2000. Its 37.77% gain for the first nine months of this year gives it a reasonable chance of extending its streak to seven calendar years.

The fund's top holdings are Samsung Electronics and Posco. The fund's grade of "A" from TheStreet.com Ratings equates to a buy recommendation.

With its investments focused half a world away from South Korea, the older and smaller

iShares MSCI Austria Index Fund

(EWO) - Get Report

has produced market gains every calendar year beginning with 2002. It kept modestly above water as the current year passed the three-quarters pole.

The iShares MSCI Austria Index is a veteran among ETFs. There were fewer than 20 such vehicles in existence when it debuted in 1996. Its biggest portfolio holdings are Ersta Bank der Oester Spark and AVM AG. The fund's "A-" grade from TheStreet.com Ratings gives it a "buy" recommendation.

There are three ETFs that have produced positive consecutive calendar-year results since 2002 but have fallen into the red since January of this year. All invest in the real estate industry.
