My latest column is up at RealMoney as part of my series on wallflowers - stocks that have little or no analyst coverage.

In this column I look at Innospec (IOSP), which makes fuel additives and other specialty chemicals that are sold primarily to oil refineries and other chemical and industrial companies. The company operates in three segments: fuel specialties, active chemicals and octane additives.

Innospec has a monopoly position in the rapidly declining business of tetraethyl lead additives for gasoline. In the past, declines in that business have overshadowed growth in the remainder of the firm. Now accounting for just 16% of total revenue, I think the lead weight is becoming less burdensome.

Innospec scores well in my models:

• Earnings momentum: Positive
• Earnings quality: Neutral
• Price momentum: Positive
• Free cash flow: Neutral
• Return potential: Positive
