Over on CAPS, fully 706 of the 755 members who have rated Zoltek -- some 93.5% -- believe the stock will outperform the S&P 500 going forward. These bulls include SuperCharge and TheHuney, who is ranked in the top 0.5% of our community.

In February, SuperCharge described Zoltek as a solid turnaround play:

Lower price producer of carbon fiber composites that are strong like steel but lightweight for efficiency … Assuming [Zoltek] is still breathing, they should be able to capitalize by selling to the wind energy industry, to deepwater drillers, and to a new generation of automakers.

In a pitch from two weeks later, TheHuney shares that bullish spirit:

At current prices, it appears as if the market believes that [Zoltek] will remain unprofitable indefinitely or that investors believe that there will never be demand for carbon fiber for wind turbines any time within the next decade. I don't agree with that. Even if demand for wind turbines stays suppressed, carbon fiber has other uses and [Zoltek] is the lowest-price player in this arena. But there's not a lot of evidence that demand for wind turbines has declined at such a rate to lead one to believe the entire industry will collapse.

Moreover, [Zoltek] has very low debt (under 20% debt-to-value) and should not have much difficulty surviving the downturn. To see a commodity stock with low debt trading well below book value in a high-growth potential industry seems insane to me.

The downturn may even help Zoltek maintain their moat even longer. I'm going with strong outperform over a 2-10 year time horizon.
