US futures are indicating a higher open as of 05:00 ET. European equity markets are off their lows but trading in narrow ranges, while Asian equities were mixed overnight. The market's focus will be on Fed Chair Powell at Jackson Hole today, but previews have downplayed the likelihood he will offer anything incremental on taper timing, with the September FOMC meeting the more likely forum. However, press reports note the potential for volatility today with a flood of Treasury options set to expire. Companies mentioned: HP, Dell, Apple (NASDAQ:AAPL), Microsoft (NASDAQ:MSFT)
