NEW YORK (TheStreet) -- Here are my weekly ETF winners and losers.
Guggenheim Solar ETF ( TAN) -6.5% Although the solar energy ETF managed to top the winners list last week, over the past few days the volatile product gave back a good portion of those gains. This type of back-and-forth action not uncommon for this fund and I encourage investors to approach this industry with caution. Looking ahead, the macroeconomic turmoil in the developed world will likely weigh on solar stocks. While aggressive traders may find this slice of the energy industry exciting, long- term conservative investors should stick to the sidelines. CurrencyShares Euro Trust ( FXE) -2.1% FXE started off the week on a strong note, powering to July and August highs. This point proved to be unsustainable, however, and the currency ETF spent the rest of the week treading lower. The euro region's trials will likely continue to dominate headlines as we move into the next week. Conservative investors should look elsewhere for international exposure.
