A Look Ahead: This Week's ETFs to Watch

U.S. stocks are coming off their worst weekly performance of the year last week and that glum showing provides fodder for those that know August is historically a rough month in which to be long stocks. Just two trading weeks are left this month and while that may sound like it could bring some much-needed relief to suddenly vulnerable bulls, it may not. After all, September is the worst month of the year for stocks. Related:

. All is not lost, however. For the selective, there are some compelling opportunities with which to ride out the rest of August. For the adventurous,

. No guarantees about which group, adventurous or conservative, will come out on top in the coming weeks, but we can say the following ETFs will almost certainly be in play this week.

Or really just about any gold or silver mining ETF. Over the past month, six of the 10-best performing non-leveraged ETFs are related to gold or silver in some way. GDX, up 20.2 percent over that time, is on the list. Consecutive closes above the $28.50 area bodes well GDX, particularly if that price range turns into new support in the even of a pullback.

The sector and its ETFs have been market leaders for over three years. A rest/pullback could finally be coming to fruition and that should benefit SCC.

Watch for the Direxion Daily Real Estate Bear 3X Shares to break resistance at $19 because if it does, the upside potential from there is considerable. As it is, DRV surged 22 percent just last week. The catalyst is easy to spot. Rising Treasury yields are bad news for REIT stocks and ETFs. Yields on U.S. government 10-years are up 30 basis points in the past month. Over that same time, eight of the 20-worst non-leveraged ETFs are REIT funds. For more on ETFs, click
