Stagnant prices? Check.
High sentiment? Check.
Declining RSI? Check.
Sell that market!
New highs can’t be ruled out, but starting from conditions like this, they will be small in relation to the likely decline.
Throw in a developing recession and high Shiller PE ratio, and you’ve got the strong possibility of a major top.
