Let's Get Ready to Roku

The streaming software and device manufacturer Roku Inc. (ROKU), which turned in a pretty good first day of trading by the way, reminds me that bulls want to see a notable uptick in virtually all forms of animal spirits here to accompany the Russell breakout. 

Beyond IPOs, some more mergers & acquisitions activity is something we have noted before. 

And I suspect if we are to see a sustained rally from here, then M&A will be one of the focal points for bulls to stave off bear arguments for the foreseeable future.
