Gas Storage Fair Price | online Calculator

Remarkably, many market players in energy market still cannot calculate the fair value of a gas storage. In particular, many of them rely on perfect foresight. We put online a simple but correct model from QuantLib. Confidence intervals are estimated as well.

NB! This time not for retail investors but for the colleagues from energy industry. Have a look at short introductory video.

Gas Storage is a relatively complex option to evaluate, esp. if there are non-trivial constraints. Remarkably, many energy companies cannot correctly evaluate even the simplest storage contracts. Moreover, they often resort to a so-called perfect foresight: the price paths are considered random but once the price path is known, it is assumed to be known completely (like at the left-hand sketch).

PUT on nVIDIA turned out to be far from perfect trade, but…

On 25.12.2016 I bought a put on nVIDIA since I found the stock extremely overpriced. I called it "nearly perfect trading decision", inter alia, because the implied volatility was though plausible but still high.

Online Option Calculator – estimate the future value of an option
