So I've seen and heard plenty recently about the SPX reaching severely overbought conditions.  Here I'll introduce RSI and then discuss three simple questions... What does that mean?  How important is it?  What do we do about it?...

Flipping through the charts this morning and noticing (once again) lots of "up and to the right" charts.  When there are lots of similar charts, I like to look for the not-so-similar charts...

The Dow chart just looked familiar this morning.  I had seen this before.  Sure enough, it turns out there are some similarities to another Dow milestone, Dow 10,000 in 1999.  Chart below, 1998-1999 on top and 2016-2017 on bottom...
