RE:Just to..(Just a rant) Summer sale? This is just how small caps trade. If you look at my profile you can figure out some of the other stocks I speculate on. There are huge gyrations, none of the moves make any sense unless you value companies with a 2 week outlook. Any sane person taking a 3-, 6-, or 9-month view would not value companies with such volatility.
The cynic in me believes that institutional players are just shaking the tree. So, if you are disciplined to go overweight on the dips and rebalance on the recoveries, then on virtually any positive-trending small cap, you will make truck loads of money.
SEV is no different.
TL;DR
Right now SEV is being conservatively valued, and is probably worth overweighting.
FWIW, it is important you don't feed the beast by trading actively (ie, paying the spread.) You can easily turn a 6 cent win into a 1 or 2 cent win, which is not enough to cover misjudgements.
