A Vector of No Magnitude

MAGNITUDE & DIRECTION

In mathematics, systems of linear equations are used to construct complex spans that can shift across multiple dimensions.  In their most basic form, each construct is made up of a series of vectors which are basically line segments.  A vector, by definition, has two components - magnitude and direction.

On Friday, the S&P closed down for the day - which by itself is not particularly noteworthy, except for the fact that it had also closed down in each of the previous 8 days as well.  This was the first time this has happened since 1980... a somewhat historic move in terms of duration.

Since September, I've noted on this blog that the market was signaling an increased likelihood of a correction so the direction of the move comes as no surprise.  What has been surprising, however, is the magnitude of a move breaking below support levels... or should I say, the lack thereof.

Going back to August of last year, the market has had two noteworthy corrections prior to this one - three if you count the fallout from Brexit which was more of an unforeseen systemic shock; but both of the technical corrections displayed the typical eruptions of volatility and volume that are associated with down moves.

For the sake of context, I'm defining a 'correction' as a breakout to the downside (breakdown) below levels of support with widening negative gaps in moving averages.

Here's the August 2015 move...

Here's last January's move...


By contrast, here's the S&P's most recent breakdown...

The differences are plain to see.

Another interesting part of the market's activity over the last couple of weeks has been the US Dollar.  The greenback has lost its mojo after previously breaking out to new highs only to give it all back in spite of the Fed giving a wink and a nod to another December rate hike.  A weakening dollar is usually a welcome sign by equities but not so in this environment.

The only thing to conclude here is that the market is simply gearing up for the US Presidential election and is pricing in the possibility of what could be viewed as an unfavorable outcome.  The price of vol has spiked ahead of Tuesday's decision so it will be interesting to see how things play out come Wednesday.

In linear algebra, the magnitude - and even direction - of a vector can be changed by applying what's known as a scalar multiplier.  In the context of domestic equity markets, the election appears to be the scalar multiple that will determine whether the magnitude and direction of this vector is augmented or reversed.

Modeling Black-Litterman; Part 1 - Reverse Optimization

  "The 'radical' of one century is the 'conservative' of the next." -Mark Twain In this series, I'm going to explore some of the advances in portfolio management, construction, and modeling since the advent of Harry Markowitz's Nobel Prize winning Modern Portfolio Theory (MPT) in 1952. MPT's mean-variance optimization approach shaped theoretical asset allocation models for decades after its introduction.  However, the theory failed to become an accepted industry practice, so we'll explore why that is and what advances have developed in recent years to address the shortcomings of the original model. The Problems with Markowitz For the purpose of illustrating the benefits of diversification in a simple two-asset portfolio, Markowitz's model was a useful tool in producing optimal weights at each level of assumed risk to create efficient portfolios.   However, in reality, investment portfolios are complex and composed of large numbers of holdin

Evidence the SPY is Overbought...

 A quick note on the recent market rally here of late.  It's plain to see the markets have been on a tear for the month of June (and going back into May for the QQQ) as the SPY closed today at its highest level in almost fourteen months. If we start to look at the historical levels, however, it appears the SPY may be overbought in the short-run and susceptible to a mean-reverting pattern. Here's the daily chart of the SPY as of today's (6/15/23) close... When looking at the distance between the closing price and the 50-day moving average (illustrated by the yellow bar), we're noticing a large gap... this can be measured by a statistic I developed which I casually refer to as "variance"... or the distance between current prices and their respective moving averages. Historically, throughout the life of the SPY (which debuted in January of '93), the variance over the 50-day moving average has peaked at a reading of 3.20... today's reading posts up at 2.49
