Trading the S&P 500 with the Lunar Cycle | Randall Ashbourne

Randall Ashbourne (2011) - [...] stock prices tend to be higher around the time of the New Moon each month and reach a temporary low point around the time of the Full Moon. Now that’s statistically speaking. And there are Lies, Damned Lies - and Statistics! [...] Many of the Lunar trading articles found easily on the internet tend to suggest the potential gains are relatively minor, or that the phenomenon inverts so often that it can’t be used as a reliable trading technique.

[...] What I discovered was that, statistically, the old assertions not only hold up, but when traded consistently over time, produce big profits for small amounts of time exposed to market conditions [...] Buying a single share of the index at the closing price of our starting date on the January 4 New Moon and holding until the close of the June 1 Solar Eclipse New Moon, produced a profit of $44.35 - 3.49% (bottom left corner of the table).
 
 
However, going Long for one share from each Full Moon close to the next New Moon close, produced more than twice the profit - $90.96. So, we were in the market for half the time and twice the profit (the FM-NM green phase label).

[...] Staying OUT of the market during all New Moon-Full Moon phases would have protected us from losing some of our buy-and-hold gains … but delivered much better profits for our Loonytoons strategy by being profitable Short trades. We were in the market ALL the time, but continually reversing positions - to get three times the profit of buy-and-hold. The darker green coloring shows the very profitable trades, the light green shows profitable trades. The rose coloring shows that only ONE “assumed” Short phase would have resulted in a trading loss. But, remember … this is overall, taking into account the full 6 month period.

[...] take advantage of the Quarter Moon dates. So, our trading strategy now becomes to open 1 position at either the New Moon or Full Moon, but to add an extra position at the First Quarter or Third Quarter date. And the table below shows a significant boost to our potential profits: Instead of relying totally on the 14 day Short from NM-FM, we add one extra Short at the 1Q Moon - boosting the overall profit from Short trades from $46.61 to $109.36. And we adopt the same strategy when we reverse to Long trades at the Full Moon - 1 Long at Full Moon and one extra Long at 3Q Moon, boosting our Long profits to $152.56.
 

Taking advantage of the extra Long or Short position at the closing price on the day of the First Quarter or Third Quarter Moon dramatically increases the profits.
 

While the buy-and-hold strategy produced a profit of 3.5%, we could have made marginally more money by Shorting the index for a couple of weeks at each New Moon; twice as much money being exposed to the market for only half of each month from Full Moon to New - and almost six times as much money by playing the odds that the “statistics” will hold true when traded automatically, but consistently, over time.
