Last week, I recommended that traders buy units of the iShares Silver Trust ( SLV) on a push above the 50-day moving average - which happened just a day later. The resulting trade would have generated gains of more than 11% as the S&P 500 lost value. If you're still in this ETF, it's not necessarily time to unload units just yet. Metals are performing well as an alternative to equities in this market. While some semblance of a correction is likely today as stocks bounce a bit, I'd recommend holding onto SLV until we see a move below $38 support. For now, consider any position in SLV to be insurance against more broad market moves lower.
