The bull market in equities is seemingly never going to end and I get more and more questions about what people should do who have missed the boat and only partially invested in the current bull market. The usual fear is that if they invest now, they might be investing at the top of the market. Another argument is that every asset class seems overvalued. Given extremely low-interest rates, bonds don’t seem a viable option, stocks aren’t cheap either and many alternative asset classes like infrastructure or REITs have become expensive as well. I have been a value investor for most of my career, but there comes a point when avoiding an asset class on valuation grounds or for fear of an imminent bear market becomes counterproductive. By standing on the sidelines for too long the opportunity costs in terms of foregone returns can become so big that it may take you years and even decades to make up for them.
