Much of the observations I shared last week are continuing to be more apparent this week. So, in case you missed it, this may be a good time to read them.
I discussed how earnings season can drive a volatility expansion in stocks, especially high growth momentum stocks. The stock market leaders can become priced for perfection, so we never know how investors will react to their earnings reports. To achieve asymmetric returns from momentum stocks, we need a higher magnitude of positive reactions than adverse reactions over time. On a quarterly basis, it can be tricky. The gains and losses as much as 20% or more in the most leading momentum stocks like Facebook ($FB), Google ($GOOGL), Twitter ($TWTR), Grub ($GRUB), and NetFlix ($NFLX) have since provided a few examples.
In Front-running S&P 500 Resistance I shared an observation that many market technicians incorrectly say support and resistance appear before it actually does. We won’t know if resistance to a price breakout exists until the price actually does pause and reverse. I suggested the S&P 500 may indeed pause and reverse, but not because the index drives the 500 stocks in it, but instead because my momentum indicators suggested the $SPY was reaching a short-term overbought range “So, a pause or reversal, at least some, temporarily, would be reasonable.” As of today, the S&P 500 has paused and reversed a little. We’ll see if it turns down or reserves back up to continue an uptrend.
In Asymmetry of Loss: Why Manage Risk? I showed a simple table of how losses compound exponentially. When losses become greater than -20%, it becomes more exponential as the gains required to recover the loss are more and more asymmetric. This simple concept is essential and a cornerstone to understanding portfolio risk management. Buy and hold type passive investors who hold a fixed allocation of stocks and bonds are always fully exposed to market risk. When the market falls and they lose -20%, -30%, -50% or more of their capital, they then face hoping (and needing) the market to go back up 25%, 43%, or 100% or more just to get back to where they were. This can take years of valuable time. Or, it could take a lifetime, or longer. Just because the markets have rebounded after being down for four or five years from their prior highs doesn’t guarantee they will next time. Past performance is no guarantee of future results.
In Trend following applied to stocks, the message was short and sweet: gains are produced by being invested in stocks or markets that are trending up and losses are created by stocks trending against us. Investors prefer to be in rising stocks and out of falling stocks. But, as I showed in Earnings season is tricky for momentum growth stocks the trick is giving the big trends enough room to unfold. In fact, applying trend following and momentum methods to stocks is also tricky. It’s a skill that goes beyond just looking at a chart and it’s not just a quantitative model.
About two weeks ago, the measures of investor sentiment showed a lot of optimism about future stocks prices, so we shouldn’t have been surprised to see some stocks fall. When a lot of enthusiasm is already priced in, investors can respond with disappointment when their stocks don’t live up to high expectations.
Much of the momentum and trend following in stocks is driven by an overreaction to the upside that can be accompanied by an overreaction to the downside. A robust portfolio management system factors these things in.
