There is a solid long-term support at 156 on Visa. This is buttressed by the .236 Fib retracement near 155 as well. The 155/156 area is strong support in case of a bearish move. Also, the recent up-days have had lower volume than the recent down-days, indicating stronger bearish sentiment. The stock is also trading near its ATH (all time high). Today's candlestick's upper wick penetrated the bollinger bands, indicating Visa is due for mean reversion. We are selling the July 160/170 srangle for credit and are thus slightly delta negative.
