Looking at the weekly chart, gold's had a decent run, but RSI is definitely overbought. I'm a bit wary of a pullback next week. Might be wise to trim some positions before Monday's open just in case. With the market closed over the weekend, anything could happen.
Update: Thinking about it more, I might actually hold a small core position through the weekend. The Iran news could really send gold soaring if things escalate. But keeping it small, with a very tight stop loss. Risk/reward is still skewed, but the potential upside is too tempting to ignore completely.
