Fear and Greed is Shifting and Models Don’t Avoid the Feelings

Investors are driven by fear and greed. That same fear and greed drives market prices. It’s Economics 101 “Supply and Demand”. Greed drives demand, fear drives selling pressure. In fact, investors are driven by the fear of losing more money when their account is falling and fear missing out if they have cash when markets go up. Most investors tend to experience a stronger feeling from losing money than they do missing out. Some of the most emotional investors oscillate between the fear of missing out and the fear of losing money. These investors have to modify their behavior to avoid making mistakes. Quantitive rules-based systematic models don’t remove the emotion.

Amateur portfolio managers who lack experience sometimes claim things like: “our quantitive rules-based systematic models removes the emotion”. That couldn’t be further from the truth. Those who believe that will eventually find themselves experiencing feelings from their signals they’ve never felt before. I believe it’s a sign of high expectations and those expectations often lead to even stronger reactions. It seems it’s the portfolio managers with very little actual performance beyond a backtest that make these statements. They must believe a backtested model will act to medicate their feelings, but it doesn’t actually work that way. I believe these are the very people who over optimize a backtest to make it perfectly fit historical data. We call it “curve-fitting” or “over-fitting”, but it’s always “data mining”. When we backtest systems to see how they would have acted in the past, it’s always mining the data retroactively with perfect hindsight. I’ve never had anyone show me a bad backtest. If someone backtests entry and exit signals intended to be sold as a managed portfolio you can probably see how they may be motivated to show the one that is most optimized to past data. But, what if the future is very different? When it doesn’t work out so perfectly, I think they’ll experience the very feelings they wish to avoid. I thought I would point this out, since many global markets have been swinging up and down. I’m guessing some may be feeling their feelings.

The CNN Fear & Greed Index shows investor fear and greed shifted to Extreme Fear a month ago as the popular U.S. stock indexes dropped about -12% or more. Many sectors and other markets were worse. Since then, as prices have been trending back up, Greed is now the driver again. I believe fear and greed both drives market prices but also follows price trends. As prices move lower and lower, investors who are losing money get more and more afraid of losing more. As prices move higher and higher, investors get more and more greedy. If they have reduced exposure to avoid loss, they may fear missing out.

This is the challenge in bear markets. In a bear market, market prices swing up and down along the way. It’s these swings that lead to mistakes. Below is a chart of how the Fear and Greed Index oscillates to high and low points over time. Investors who experience these extremes in emotion have the most trouble and need to modify their behavior so they feel the right feeling at the right time. Or, hire a manager with a real track record who can do it for them and go do something more enjoyable.

The Trend of the U.S. Stock Market

When I say “The Trend” that could mean an infinite number of “trends“. The general definition of “trend” is a general tendency or course of events.

But when I speak of “The Trend” I mean a direction that something is moving, developing, evolving, or changing. A trend, to me, is a directional drift, one way or another. When I speak of price trends, I mean the directional drift of a price trend that can be up, down, or sideways.

Many investors are probably wondering about the current trend of the U.S. stock market. So, I will share a quick observation since one of the most popular U.S. stock indexes seems to be right at a potential turning point.

Below is a 6 month price chart of the S&P 500 stock index. The S&P 500® is widely regarded as a gauge of large-cap U.S. equities. Clearly, prior to late August the stock index was drifting sideways. It was oscillating up and down in a range of 3% to 4% swings, but overall it wasn’t making material higher highs or lower lows. That is, until late August when it dropped about -12% below its prior high. Now, we see with today’s action the stock index is attempting reach or breach it’s very recent peak reached on August 27th. If the index moves above this level, we may consider it a short-term uptrend. We can already observe the index has made a higher low.

You can probably see how the next swing will determine the direction of the trend. If it breaks to the upside, it will be an uptrend as defined by “higher highs and higher lows”. Although, that is a very short-term trend, since it will happen within a more intermediate downtrend.

My point is to observe how trends drift and unfold over time, not to predict which way they will go, but instead to understand and define the direction of “the trend”. And, there are many different time frames we can consider.

If this trend keeps going up, supply and demand will determine for how long and how far. If it keeps drifting up, I would expect it may keep going up until some inertia changes it. Inertia is the resistance to change, including a resistance to change in direction.

But if it instead goes back down to a new low, I bet we’ll see some panic selling driving it even lower.

The real challenge of directional price trends is if this is the early stage of a larger downward trend (like a bear market), there will be many swings along the way. In the last bear market, there were 13 swings that ranged from 10% to 27% as this stock index took about 18 months to decline -56%.

Below is the same stock index charted with a percentage chart to better show the percent changes over the past 6 months. You can probably see how it gives a little different perspective.

I don’t necessarily make my tactical decisions based on any of this. I enjoy watching it all unfold and I necessarily need to define the trend and understand it as it all plays out. I want to know what the direction of the trend is based on my time frame, and know when that changes.

I believe world markets require active risk management and defining directional trends. For me, that means predefining my risk in advance in each position and across the portfolio.
