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?

1. Sales tumbled by 18.8% annually over the last five years, showing market trends are working against its favor during this cycle
2. 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
3. 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?

1. Sales tumbled by 2.4% annually over the last two years, showing market trends are working against its favor during this cycle
2. 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
3. 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.

One Stock to Buy:

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?

1. Estimated revenue growth of 11.6% for the next 12 months implies its momentum over the last two years will continue
2. Earnings per share grew by 31.9% annually over the last two years, massively outpacing its peers
3. Negative free cash flow margin has improved over the last five years, showing the company is one step closer to financial self-sufficiency

At $7.25 per share, FuelCell Energy trades at 1.7x forward price-to-sales. Is now the right time to buy? Find out in our full research report, it’s free.
