Rapid spending isn’t always a sign of progress. Some cash-burning businesses fail to convert investments into meaningful competitive advantages, leaving them vulnerable.
Negative cash flow can lead to trouble, but StockStory helps you identify the businesses that stand a chance of making it through. Keeping that in mind, here is one high-risk, high-reward company investing aggressively to carve out a leadership position and two to leave off your radar.
Two Stocks to Sell:
Magnachip (MX)
Trailing 12-Month Free Cash Flow Margin: -30.3%
With its technology found in common consumer electronics such as TVs and smartphones, Magnachip Semiconductor (NYSE: MX) is a provider of analog and mixed-signal semiconductors.
Why Are We Out on MX?
- Sales tumbled by 18.8% annually over the last five years, showing market trends are working against its favor during this cycle
- 42 percentage point decline in its free cash flow margin over the last five years reflects the company’s increased investments to defend its market position
- Short cash runway increases the probability of a capital raise that dilutes existing shareholders
Magnachip’s stock price of $3.09 implies a valuation ratio of 0.6x forward price-to-sales. Read our free research report to see why you should think twice about including MX in your portfolio.
Genco (GNK)
Trailing 12-Month Free Cash Flow Margin: -27.4%
Headquartered in NYC, Genco (NYSE: GNK) is a shipping company that transports dry bulk cargo along worldwide maritime routes.
Why Should You Sell GNK?
- Sales tumbled by 2.4% annually over the last two years, showing market trends are working against its favor during this cycle
- Performance over the past two years shows each sale was less profitable as its earnings per share dropped by 43.5% annually, worse than its revenue
- Capital intensity has ramped up over the last five years as its free cash flow margin decreased by 58.6 percentage points
Genco is trading at $23.66 per share, or 20.5x forward P/E. Check out our free in-depth research report to learn more about why GNK doesn’t pass our bar.

FuelCell Energy (FCEL)
Trailing 12-Month Free Cash Flow Margin: -74.2%
Founded in 1969, FuelCell Energy (NASDAQ: FCEL) is a leading manufacturer and developer of carbonate fuel cell technology for stationary power generation.
Why Will FCEL Outperform?

- Earnings per share grew by 31.9% annually over the last two years, massively outpacing its peers
