Running out of steam is best seen via legendary investor John Templeton’s four-phase quote: “Bull markets are born on pessimism, grow on skepticism, mature on optimism and die on euphoria.” Upon reaching euphoria bull markets lack energy to propel them further. Bulls climb the legendary “Wall of Worry,” and when all worries wane to well-worn whitewashing, you’re out of steam.
So I wait, watch and remain bullish, noting we’re still, in Templeton’s parlance, straddling skepticism and optimism, and, hence, abundant force propels this bull on. Without a wall we’re maybe halfway through.
