I always love to take readers to an important part of the market that's maybe under-talked-about. 

Netflix Inc (NFLX - Get Report) impressed Tuesday with its intenational subscriber growth, even with some reports saying the Eurozone is in for a slow down. 

But Alcoa Corp (AA - Get Report) reports third-quarter earnings Wednesday after the closing bell. Aluminum prices have risen in large part because of Trump's tariffs. Its last quarter beat expectations because of both higher prices and strong shipment volumes. It will be interesting to see what aluminum demand and pricing looks like now, as Wall Street ponders whether or not we are at the peak of the economic cycle. 

My newsletter breaks that down a bit more. 

Also, don't forget to look at regional bank earnings. Most of the large cap banks reported strong earnings, including Goldman Sachs beating estimates again, as TheStreet's Jim Cramer points out on the Action Alerts Plus website. Some of the smaller guys like M&T Bank Corp.  (MTB - Get Report) , U.S. Bancorp  (USB - Get Report)  and Bryn Mawr Bank Corp  (BMTC - Get Report)  report. They combine for $107 billion in market cap. 

Meanwhile, Applied Materials Inc. (AMAT - Get Report) is another company not always talked about, as analysts debate its outlook. Shares of the Santa Clara, California-based semiconductor are up around 3% in pre-market trading Wednesday, building on a 4% advance on Tuesday, writes RealMoney's Kevin Curran.
