You're asking a trick question.
"Safe" as an investment term implies "no loss of principal" or "insured yield". So, no, your dividend stock is not safe.
"Long term buy and hold"-- is there anyone else on this board who's held an individual stock for more than 10 years? We're there with the Berkshire Hathaway shares we started buying in 2001, but we've sold some to rebalance. Why would you hold CVC, or why would you sell it? Would you hold CVC for more than a decade, or would you find some rationale to get rid of it?
"Play" implies that you're not investing, you're speculating or gambling. So this probably doesn't have any place in your asset allocation. Of course you could take the UncleMick approach of setting aside 10-15% of your portfolio for testosterone-poisoned hormone-influenced hunches.
With those caveats in mind, I think this is the best blog I've ever seen for individual dividend investors:
Dividend Growth Investor: How to invest in dividend stocks
and I'd also recommend Josh Peters' "The Ultimate Dividend Playbook".
In my opinion, at your current level of analysis you're just eyeballing a value trap.
