If you were to punch me in the face 10 times, then stop and promise me that you would never punch me in the face again, then punched me in the face another 10 more times, and repeated this process five more times, I would still find you more trustworthy than Sierra. Sierra is nothing more than a bad blog run by hacks who lie to manipulate a stock's PPS. Read this disclaimer at the bottom of the blog's page. It's probably the truest statement on the blog.
