High performance fibers exhibit extraordinary mechanical properties. These high performance materials are made of ceramics, metals, carbon, and polymers. High performance polymer fibers integrate excellent mechanical properties with low weight.

High tensile strength and high resilience are the two main properties of the high-performance fibers. For some polymer materials, high tensile strength can be obtained using high drawing ratios and high molecular orientation (e.g. for Aramid / Kevlar) duri

The dilemma of the long stock position is unending downside risk. This is where options serve their best purpose: as tools for portfolio management. Rather than use only as speculative and high-risk market plays, strategies like the synthetic short stock position protect against downside loss and, unlike the better-known covered call, offer a practical alternative to selling and taking profits. This position combines a long put and a short call. In a pure synthetic short, no stock would be held
