In this paper, long memory and time varying hedging opportunities between clean energy, West Texas Intermediate (WTI) crude oil and technology share prices were analyized between 3 May 2005-16 October 2019. The relationships were investigated by DECO-FIGARCH model with daily frequencies. According to findings, it is understood that volatility clusters were determined in crude oil, alternate source energy and technology returns. Due to this useful information shocks reach to all three investment tools and being eliminated at hyperbolic speed, also the volatility spillover lasted for a long time. The most important finding of the research is that long position risks arising in both clean energy and technology sectors can be effectively and efficiently hedged with WTI futures contracts. On the other hand, it was determined that WTI can be added to the portfolio in order to reduce the risks of portfolio to be established with clean energy and technology sector.
