That is a VERY good point. 15 is indeed a fair value, and so the current market is overvalued by 26%.
This would imply a current FAIR VALUE price of the S&P 500 of 872 making a P/E of 15...

There does not seem to be any Inverse Natural Gas ETF, sadly.
The Canadian one seems to be the only one, but it is leveraged (2x) and Canadian. So of no use to me.
If anyone does find an Inverse, then please let me know!
Shorting ETFs is a pain. My broker charges hefty fees and then sometimes they close a position at their discretion and without notice - a "buy in".
So it is too risky and expensive to short an ETF - at least for me.
Normally there are ETFs for for Short and Long of almost everything. Hence...
