MNKD Free Cash Flow Trend

Free Cash Flow trendline for MNKD — Free Cash Flow trendline for MannKind Corporation

Hmm, we can't give any reliable projection for MannKind Corporation's growth rate. The company either has too few years of historical data for us to examine, or it's in the habit of losing money.

None of this means it's a bad stock. Maybe it's new and growing quickly, or maybe it's turning things around. We can't say anything sensible about it, so we won't say it's obviously undervalued right now. Proceed at your own risk!

Advantages	Disadvantages	Neutral
This company is solid.	This stock looks overpriced. This company is not making money. This company has wild ups and downs.	This company pays no dividend.

Inside the MNKD Numbers

	MNKD Price (MannKind Corporation stock price per share)	$4.19
× PE Ratio Versus Sector The PE ratio measures the reported earnings of a company to its current stock price. While earnings are easy to manipulate on the balance sheet, this ratio gives you a sense of what buyers are willing to pay for the stock—what they believe it will do in the future. Comparing a stock's PE to the average PE of companies in its industry gives you a sense of market sentiment about the stock and how well it fares financially. It's not the only number, nor the most important, but comparing similar companies is valuable. A ratio far above or below that of its peers is significant. Industries are more specific than sectors, so companies within most industries are more similar than are companies within an industry. Be aware that the size and customers of companies are important to their prospects. Close ^[?]	PE Ratio versus Sector	88% lower than other Unknown stocks

× Cash Yield The cash yield of a stock is the ratio of free cash per share—real dollars available after bringing in revenue and paying bills—to the current price of the stock. It's similar to the PE ratio, but it's less prone to manipulation through accounting practices. In general, the less you have to pay to make more money, the better. Close ^[?]	Cash Yield	-3.26%
× Free Cash Flow Jitter The free cash flow jitter of a stock measures how much the company's free cash flow varies from its historical trend, on average. While it's always nice to make more money than you expected, a company with predictable free cash flow is stable and good. A company with wild swings in its free cash flow warrants further research. In general, the lower this number, the better. Close ^[?]	Free Cash Flow Jitter	67%
