Technical- seeing buying sign in volume and crossing significant moving averages.
Deep Value- current below tangible book value, meaning there are more hard assets and cash on the books than the stock price reflects.
Earnings power- stock loses money for a handful of year before it breaks even, but on a 10 year view it become profitable, giving an exit if stock doesnt rise in short term.
Typically on tangible book value plays, id look for a 2x with small odds of more. Ideally I will sell half at 2x and keep the remainder 1/2 for free for long term.
