CYCLICAL SPX vs JPY correlation - what it means (SHORT SPX)

FX:SPX500   S&P 500 Index
as you can see below 8/12 months of the time the JPY is heavily negatively correlated with the spx             , normally between 80-90%, there also is a pattern, that the JPY/SPX stayd negatively correlated for 8 months before turning positively correlated for about 4 months, this cycle continues unbroken below..

as we can see by the red correlation being above 0, The markets are in the 4 month "positive" correlation phase, this to me is a bearish signal for SPX             bulls as
1. we are at the end of the average 4 months of positive corrs, before the market turns back to negative, thus this may be a signal that the market is going to turn bearish (in order for the correlation to go back to negative).
2. the positive correlation has tailed off in recent days, signalling it is an end to the positive trend and that the negative trend may start soon

the reason i have chosen weaker markets to correct the pair back to its negative correlation, rather than weaker JPY is because:
1. the spx             is near highs so a downside turn around is more probable.
2. volume and volatility are at yearly lows - low volume means low interest in pushing the price up and the market is effectively in limbo, low volatility means volatility is likely to pick up and in turn push investors away.
3. marco econ             risks/ uncertainties such as the feds tightening cycle and brexit will surely continue to be priced into long JPY and short risk assets (spx)             - suggesting that JPY weakness will not be the one to give in, it will be the stocks.
4. the USDJPY             isnt at all time low levels, there is more room for JPY buying before any liquidity tightens - especially if the BOJ continue to ease.

BOJ/JPY background;
the BOJ seemingly has no control over their economic target inflation , CPI             is consistently negative even after years of easing and high employment vs the $ fed who are doing the opposite and hiking rates with relative success, IMO             because of these factors the USDJPY             should be at 130.
However its not. it is at 109, and JPY serving as a risk off asset is the ONLY explanation for its strength. there is no other macro economic reason for JPY's strength, apart from safety seeking.
(JPY continues to be a net creditor economy - this is where the perceived safety comes from)

If anyone else has a different reason for why the JPY is so strong, id love to hear it
Appreciate your work. Feedback: noting the federal reserve has not hiked interest rates, albeit one tiny increase a long time ago now of just 0.25 points. I don't believe there is a correlation between the yen and the SPX. One could put up any chart and find some type of relationship.
you are right they have only hiked once.. the point is that the BOJ and FED have diverging policies.. the BOJ is still easing and may need to do more, whereas the FED is actively hiking.. a 25bps hike was a 100% increase in the rate from 0.25 to 0.5% so it is actually quite significant.

This divergence massively impacts the supply/demand of the pair, YEN's supply increases, whilst demand for USD deposits increases, which SHOULD push the pair much higher.
With regard to " i dont believe there is a correlation between the yen and SPX", there is a strong correlation between the two. Most people know that the JPY is a "safety" asset that investors seek in times of uncertainty/volatility - just like bonds and Gold.

Please see the article i posted trying to show the degree of the correlation.

I do agree that in some circumstances correlations are drawn naively but in this example it is true.. infact there are few examples of where there isnt correlation either positive or negatively because all financial markets are linked in one way or another as investors only have a limited choice of where to allocate their assets for a return.

Yes, but there is another problem you have. As soon as someone sees a correlation that is about the time it changes. Noting my critiques, if wrong, help you strengthen your argument. Happy trading.
i disagree.. gold and bond and yen have been risk-off assets since the begining.. do you agree that gold and bonds are negatively correlated with stocks/equity?

They are not always....that is the problem with correlation.
in strong markets the negative correlation is almost always 80%+. this imo is undeniable!

However, please dont confuse my bid for correlation as a statement of "correlation is causality". If i was saying correlation was causality, you would be right, correlation wouldn't be around for long as people would notice and it would become priced out.

Correlation is merely imo, viewing two assets move at the same time together or against to some degree - one asset doesnt cause the other to move however.

If this was the case, then everyone would be able to arbitrage profit which ofc is impossible.

Thanks for your feedback, i enjoy the discussion.
