There are close to 20,000 publicly traded stocks in the United States. Only about 4,000 of those are actively traded on a major exchange such as the NYSE or Nasdaq. Even then, most of those are unworthy of owning a spot in your portfolio.
Sometimes the decision to not buy a stock depends on the type of portfolio you're building. Sometimes it requires looking at a company's market position, evaluating future risks, and deciding you'd be better off parking your hard-earned money elsewhere. That doesn't necessarily make it personal between you and the stock you're turning down. It just makes it right for you, personally.
With that in mind, I have clear reasons for never planning to buy Flotek Industries (NYSE: FTK), CVR Partners LP (NYSE: UAN), and Chemours Co. (NYSE: CC).
