Where will the S&P 500 go next? Let the market tell you.
by Adam Grimes
Given the action in US stocks this week, I thought this might be a good time to share a few thoughts about the market. I hope to be able to show you a way to think about the market that will cut through all of the fear, hype, exaggeration, and other āstuffā out there that makes the job of trading even harder than it is.
Be an intelligent consumer of financial media
First, letās talk about news and psychology: There are a number of reasons for what has happened this week in the markets. There always are, and I would respectfully submit that it is probably a mistake to focus attention on those reasons. By the time you know about those reasons (or have read about them in the news), everyone knows; many people knew before you did, and all of that information is probably already in the priceāitās already baked into the cupcake, so to speak.
The news and hype around the reasons for the marketās movements often serve to exaggerate the swings of the individual trader/investorās psychology. You must be aware of that. When you find yourself thinking āoh, noā, āwhat ifā¦.?ā or thinking about extreme scenarios, take a step back and realize that the information you are immersed in is usually cast in a way to create those reactions. You rarely receive truly unbiased and pure information. Iām not saying ignore the news, but we must always strive to be intelligent consumers of financial newsāand this means removing the emotional part.
Putting the marketās moves in perspective
Now, letās talk about the marketās movements and Iāll show you a way to think about the future. Though the world is a complex and interconnected web, the S&P 500 is a very good proxy for the US market as it captures a significant cross-section of the market. Smaller caps may do some weird things, and the mega caps (like the DJIA) are not the best guide to the broad market for a number of reasons. No answer is perfect and we always do need to be aware of the connections (my āindex universeā of domestic and global stock indexes covers about 25 that I watch intimately (i.e., constantly, intraday) and another 30 or so that I look at maybe twice a day), but the S&P 500 is a pretty good instrument. With that in mind, letās take a look at some recent history. Apologies that the chart may be a bit small, but I needed to fit a good chunk of history on the screen:
So, the first thing I would call your attention to is the set of bars at the bottom of the chart. These bars are what I have called SigmaSpikes, which are simply each dayās return, expressed as a standard deviation of the previous 20 trading days. This allows a quick look at volatility-adjusted returns, and is a good answer to the āwas that a big move?ā question. A few things stand out: we have roughly a dozen days each year that are bigger declines than -2.0 standard deviations. Some years less, some years more, but even in extreme years like 2000, or 2007-2009, not as many more as youād expect. Looking at the chart above, you can see that there isnāt really anything unusual going on hereāwe havenāt had a lot more very weak days than usual.
Also, notice that the spikes do tend to cluster together. This tells us that once we have some large declines, weāre likely to have more volatility in the near futureācertainly worth keeping this in mind over the next 3-4 weeks. This is how the market usually works, so donāt panic when we have a few more strong down days. Next, letās look at the weekly chart for a longer perspective:
Technical traders and analysts are often accused of being myopic, but we donāt have to be. This is a trendline that Iāve had in place and have been watching in my published research since late 2012. We touched this trendline in October of 2014, and have just now come down to the trendline again.
Trendlines deserve some attention, but they donāt, in my experience, work like you might think. There are very few points where we can say āthe trend is over because the trendline is brokenā, so do be careful of that type of āanalysisā. (And weāre seeing a lot of it in recent weeks.) More often, trendlines are broken, perhaps suckering in naive trendline traders, and then the moves reverse. Iāll also throw out that thereās not a shred of evidence that suggests any ratios (including the Fibonaccis), moving averages, trend indicators, or other tools have a lot of predictive value. So what does matter?
What happens next is whatās important
Hereās a good way to think about it: The market usually moves in alternating waves of with trend strength (or weakness, for a downtrend), interspersed with pullbacks against that trend. (This is why trading pullbacks can be such a lucrative strategy.) The October 2014 selloff is a good model, and thatās the only time in recent years I started looking for swing shorts. Take a look at a chart of what might have been:
In October 2014, the selloff in stocks was strong enough (i.e., generated enough downside momentum) that we might reasonably have looked for another leg down. If that scenario was in play, what we āshould haveā seen was a fairly slow bounce, setting up some kind of flag/pullback, that would pretty quickly break to new lows. If that had happened, there was a possibility that weād see continued legs of selling and the eventual breakdown of trends on higher timeframes. This is a good roadmap for how lower timeframe trends can have an impact on higher timeframes.
Instead, what happened? The market turned around, rocketed higher, and we knew, literally within the space a few days, that this wasnāt an environment in which we were likely to find good shorts. Instead of the slow bounce, we got a hard bounce and the market quickly went to new highs. Following the decline, that type of bounce was unusual, but it was a clear message from the market.
I think this type of action is going to be our best guide here. Weāve had a lot of selling pressure this week, and Iām writing this intraday Friday, so we might have even more by the end of the week. (Likely, since people do seem to square up positions ahead of the weekend.) However, there is no pattern or trendline or any sentiment indicator that is going to paint a reliable guide for the way forward. Our best insight will come from the market itself over the next few weeks. To understand that message most clearly, we must try to see things for what they really are and remove the emotional component from our analysis.
One last thought: the market tends to surprise everyone. Thatās just a little bit of āhard knocksā type of experience that we might factor into our subjective analysis. Letās see what the next few weeks bring.
