Miners went up 20% in a month. If holding for years, can still keep holding.
For others trying to "outsmart" the market, a sell now, or if/when GDX crosses below 46.5.
Up 20% in a month is too good to be true. In a market that pays 3% interest on 30 year federal bonds, best to take profits and buy back later.
This counters my "time to start buying" miners back in July, near term. For a true professional, subscribe to Gary of Smart Money Tracker.
