There are a lot of debates whether the current stock market is the longest one in history or not. I am in the group of people who thinks that’s not the case. I think this market had a lot of corrections since the bottom in 2009 or since 2013 which was the start of a new secular bull market in my opinion.
Even if you focus only on the US stocks one could argue that the market was in a correction during the 2015-16 period. But for the most of the world markets did not even have a chance to take its former all time highs. Regardless of your or my opinions we have to respect what the market is doing and act accordingly.
And the fact is that most stock markets are under-performing the US market. A nice example of a lagging market as a class are merging markets or $EEM ETF.
