NEW YORK ( TheStreet) -- TheStreet.com Ratings initiated coverage of 13 exchange traded funds, assigning seven of them "buy" ratings.Five earned "sell" ratings and one was labeled "hold." Six of the seven "buy"-rated funds received our highest rating, A-plus. The highest-rated and best performing ETF among them was the Direxion Technology Bull 3X Shares Fund ( TYH), which has more than tripled in the past year. This fund is triple leveraged to the daily performance of the Russell 1000 Technology Index, whose members include Microsoft ( MSFT), Apple ( AAPL), IBM ( IBM) and Google ( GOOG). Four other bullishly leveraged ETFs that bet on precious metals or international markets earned "buy" ratings. The bearish versions of these funds earned "sell" ratings after taking massive losses in 2009. With an average daily trading volume of 517,222 in 2009, the leveraged funds were more popular than the three newly rated unleveraged funds, which averaged 7,534 shares a day. While leveraged funds are designed for short-term trading, two of the "buy"-rated unleveraged funds are meant for long-term investors. The iShares S&P Target Date 2040 Index Fund ( TZV) is intended for investors who aim to retire in 2040. It invests in other iShares funds, including those that follow the S&P 500, the MSCI EAFE indices. The other unleveraged fund, the WisdomTree LargeCap Growth Fund ( ROI), was one of the best-rated equity funds last year.
