Seasonax Event Studies

As our readers are aware by now, investment and trading decisions can be optimized with the help of statistics. After all, market anomalies that have occurred regularly in the past often tend to occur in the future as well. One of the most interesting and effective opportunities to increase profits while minimizing risks at the same time is offered by the event studies section of the Seasonax app.


A recent event that had quite an impact on certain markets… [PT]


And here is one of the markets that was surprised out of quite a few ticks by the UK election – a move from 1.2960 to ~1.27420 in cable in half an hour doesn’t happen every day (although the frequency of such moves has increased of late… the UK is apparently the mother of all election surprises). [PT] – click to enlarge.


As a pertinent example for this, the Federal Reserve Bank of New York published a study in 2011 which examined the effect of FOMC meetings on stock prices. The study concluded that these meetings have a substantial impact on stock prices – and contrary to what most investors would tend to expect, mainly before rather than after the announcement of the committee’s monetary policy decision.


Study Shows: Time Period Shortly Before the FOMC Announcement Most Important for Stock Prices

The impact is so strong, that it would have been possible to achieve almost the entire cumulative return of the S&P 500 Index since 1998 if one had invested exclusively in the days when FOMC meetings were held.

The chart below illustrates the situation. The blue line shows the trend in the S&P 500 Index since 1998, indexed to 100.  The green line depicts the cumulative return of investing solely on FOMC meeting days, the red line shows the cumulative return of all remaining trading days.


S&P 500 Index, FOMC meetings (green), other trading days (red), 1998 to 2017.  A mere 16 trading days per year generated almost the entire return of the index!


As you can see above, one could have made a profit almost equal to the “buy & hold” return while taking substantially less risk by investing exclusively during FOMC meetings – which take up a mere 16 trading days per year. By contrast, the red line is lagging by a wide margin. That means that just 6.3 percent of all trading days generated considerably larger profits than all 93.7 percent of the remaining trading days combined!


FOMC Event Study on the Seasonax app: S&P 500 Index in the days surrounding the announcement over the past 15 years  (the average of 120 events). The highlighted area is relevant for short term traders: buying 2 days before the announcement and selling 3 days after the announcement was on average the most profitable approach. At the bottom one can see the cumulative profit of this particular strategy (i.e., the holding period), as well as the returns of every single event. Details on these data can be called up separately. Note: the annualized return was 27.28%. [PT] – click to enlarge.


Hence it definitely made a lot more sense to buy stocks in the days leading up to FOMC meetings than buying them after the announcement. Conversely, it was possible to optimize the timing of one’s sales after the announcement.  As this approach illustrates, the study of events is definitely useful for conservative investors as well – it is not just of interest to short term traders.


FOMC Meetings Also Have an Impact on Other Markets

Do FOMC meetings only affect stock prices? What about currencies,  bonds and commodities? Obviously, FOMC meetings have an impact on other markets as well. However, while the effect on stock prices  is at least known to some investors by now due to the publication of the Fed study, the same cannot be said of other markets.

That is where the Seasonax app comes in. With its help one can examine how important events affect various asset classes within seconds. This knowledge will give traders/ investors an edge over other market participants.


New Seasonax Release Contains 77 Distinct Event Studies

The newest release of the Seasonax app will become available in coming days. A number of functions were expanded in the annual seasonality and intra-day order optimization areas and a few bugs were fixed. The biggest change though is the addition of new event studies. In total 77 distinct event studies can now be examined and can be linked to every instrument available on Bloomberg Professional or Thomson-Reuters.

How does the euro, the DAX or the price of crude oil typically react to interest rate hikes by the Fed, to elections in the UK or to FOMC meetings? These are just some of the questions you will be able to find the answer to with just a few mouse clicks on Seasonax.

Dear Readers!

You may have noticed that our so-called “semiannual” funding drive, which started sometime in the summer if memory serves, has seamlessly segued into the winter. In fact, the year is almost over! We assure you this is not merely evidence of our chutzpa; rather, it is indicative of the fact that ad income still needs to be supplemented in order to support upkeep of the site. Naturally, the traditional benefits that can be spontaneously triggered by donations to this site remain operative regardless of the season - ranging from a boost to general well-being/happiness (inter alia featuring improved sleep & appetite), children including you in their songs, up to the likely allotment of privileges in the afterlife, etc., etc., but the Christmas season is probably an especially propitious time to cross our palms with silver. A special thank you to all readers who have already chipped in, your generosity is greatly appreciated. Regardless of that, we are honored by everybody's readership and hope we have managed to add a little value to your life.

      Stretched to the Limit There are good reasons to suspect that the bull market in US equities has been stretched to the limit. These include inter alia: high fundamental valuation levels, as e.g. illustrated by the Shiller P/E ratio (a.k.a. “CAPE”/ cyclically adjusted P/E); rising interest rates; and the maturity of the advance.   The end of an era - a little review of the mother of modern crash patterns, the 1929 debacle. In hindsight it is both a bit scary and sad, in...

      Fake Responses  One month ago we asked: What kind of stock market purge is this?  Over the last 30 days the stock market’s offered plenty of fake responses.  Yet we’re still waiting for a clear answer.   As the party continues, the dance moves of the revelers are becoming ever more ominous. Are they still right in the head? Perhaps a little trepanation is called for to relieve those brain tensions a bit?  [PT]   The stock market, like the President,...
  • Despondency in Silver-Land
      Speculators Throw the Towel Over the past several years we have seen a few amazing moves in futures positioning in a number of commodities, such as e.g. in crude oil, where the by far largest speculative long positions in history have been amassed. Over the past year it was silver's turn. In April 2017, large speculators had built up a record net long position of more than 103,000 contracts in silver futures with the metal trading at $18.30. At the end of February of this year, they held...
  • US Stock Market – The Flight to Fantasy
      Divergences Continue to Send Warning Signals The chart formation built in the course of the early February sell-off and subsequent rebound continues to look ominous, so we are closely watching the proceedings. There are now numerous new divergences in place that clearly represent a major warning signal for the stock market. For example, here is a chart comparing the SPX to the NDX (Nasdaq 100 Index) and the broad-based NYA (NYSE Composite Index).   The tech sector is always the...

      Lord, Grant us Chastity and Temperance... Just Not Yet! Most fund managers are in an unenviable situation nowadays (particularly if they have a long only mandate). On the one hand, they would love to get an opportunity to buy assets at reasonable prices. On the other hand, should asset prices actually return to levels that could be remotely termed “reasonable”, they would be saddled with staggering losses from their existing exposure. Or more precisely: their investors would be saddled...
  • US Equities – Mixed Signals Battling it Out
      A Warning Signal from Market Internals Readers may recall that we looked at various market internals after the sudden sell-offs in August 2015 and January 2016 in order to find out if any of them had provided clear  advance warning. One that did so was the SPX new highs/new lows percent index (HLP). Below is the latest update of this indicator.   HLP (uppermost panel) provided advance warning prior to the sell-offs of August 2015 and January 2016 by dipping noticeably below the...

      Ballistically Yours One nearly-famous gold salesman blasted subscribers this week with, “Gold Is Going to Go Ballistic!” A numerologist shouted out the number $10,000. At the county fair this weekend, we ran out of pocket change, so we did not have a chance to see the Tarot Card reader to get a confirmation.

  • US Stock Market – How Bad Can It Get?
      SPX, Quo Vadis? Considering the Crash Potential In view of the fact that the stock market action has gotten a bit out of hand again this week, we are providing a brief update of charts we have discussed in these pages over the past few weeks (see e.g. “The Flight to Fantasy”). We are doing this mainly because the probability that a low probability event will actually happen has increased somewhat in recent days.   Robert Taylor and Deborah Kerr cast wary glances at their...
  • Yosemite Sam is Back!
      Dubious Picks Unless this is part of another cunning negotiation tactic, the Donald's recent cabinet nominations have to be considered highly dubious, to say the least. First he promoted Mike Pompeo from his CIA post to the position of Secretary of State – removing the eminently reasonable, and as we believe widely underappreciated Rex Tillerson. Pompeo is mainly known for sharing Trump's irrational dislike of the  nuclear deal with Iran, which was pretty much the only laudable policy...
