What this transaction means for investors Insider transactions aren't the final word on a stock. In fact, many occur for reasons having little, if anything, to do with a company's performance. Insiders sell as part of pre-arranged sales plans, for tax withholding, and for estate planning, for example. Therefore, investors should always return to a company's fundamentals to get a true measure of how it is performing -- and whether it is a smart investment. With that in mind, let's have a look at Diamondback Energy (FANG). Firstly, FANG has performed very well over the last few years. Since 2021, FANG has generated a total return of 238%, equating to a compound annual growth rate (CAGR) of 27.6%. That's well ahead of the S&P 500, which has delivered a total return of 84% over this same period, with a CAGR of 12.9%. One reason FANG has performed so well is that it is a cash-flow juggernaut. The company has grown its free cash flow from just under $2.0 billion in 2021 to nearly $6.5 billion now. In turn, FANG has delivered massive shareholder returns through two mechanisms. First, it has aggressively bought back its own shares. Second, it has increased its dividend; its dividend yield now stands at 2.1%. All in all, FANG is an energy stock worth considering, given its solid long-term performance and steady cash flow. Should you buy stock in Diamondback Energy right now?
