Allow for short-term USD/CHF weakness, says Commerzbank analyst Karen Jones. The spot charted a key-day reversal or a bearish engulfing pattern if you're looking at Japanese candlesticks, and both mean the same, says Jones, a touch of short-term weakness ahead.

Now at 0.9486, she sees risk towards support at 0.9450, 0.9407 and 0.9317 on a break. Longer term Jones remains bullish while support at 0.9091 holds, with targets of the recent 0.9595 high and then the 2011 peak of 0.9784.
