One advantage of sticking to my own view of the markets is that it allows me to tune out the noise, and there's plenty of noise to tune out.
Are markets really extended either in terms of time or valuation? I don't think so. If we use January 2016 (rather than March 2009) as the beginning of the current bull, then we're still in the early innings. Valuations in the US may be somewhat extended, but the valuation of global markets (as a whole) is not.
In my opinion, the world economy is still in expansion mode, with its 'boom' period still ahead. Sitting out the remainder of the current cycle (easy to do if we read media headlines re an imminent global trade war, an inverted yield curve, or predictions of the next crash) may turn out to be an expensive mistake.
April 22, 2018? I think it's a great time to be long the global market!
