Vivint Solar, Inc. (VSLR)

[GoldDog83]

The stars didn't exactly align for Vivint, a residential solar provider, in 2017. At one point they more than doubled before melting. They ended 2017 with a gain of 4%. We recently noted that "Vivint has consistently lost money and run negative gross margins." They don't seem to be selling points for the stock, but that didn't stop Cacti from buying 10,000 shares in the fourth quarter.
