The markets posted another week of gains despite weakness from Apple (AAPL  ). The tech company had it's worst week in over a year as concerns about the new watch, it's glitches and the iPhone 8 sales pushed the stock lower by over 5% on the week.

This week ahead investors will continue to watch for more weakness in tech names along with a handful of news events coming out of Washington. As it stands now it seems that the Republicans' newest attempt to repeal Obamacare has been met with many Republican's holding out against the effort. For now there are not enough votes to push the bill past and that could have an impact on healthcare stocks early in the week. While there is still time, as of now it seems that there may not even be a need for a vote.

In global news, the tensions between President Trump and North Korean leader Kim Jong Un seems to be peaking again. Over the weekend President Trump took to twitter again to say that the North Korean leader "Won't be around much longer." This back and forth between the world leaders hasn't shaken the markets yet, but with US bombers being sent to fly off North Korea's coast it has one foreign minister claiming that "an armed conflict is inevitable".

While this week could be a volatile one, there have been many weeks prior where traders would have thought the same. What will drag the markets lower? That's the $64,000 question at the moment and for now, no one seems to have the answer. The S&P 500 remains at record highs, the Dow as well. The Nasdaq 100 will likely be the index in focus as it has been the weakest out of the group. All indices still remain very much in an uptrend at this point, and for now investors are calm.
