If you feel as though you are walking through an Alice in Wonderland film set, you are probably not alone.
It appears “Out of sample” market experiences are proliferating across many market measures.
I believe this “out of sample” experience is the direct result of conflict between two massive forces colliding at an accelerating rate. The natural organic development of markets, and unprecedented interventions from policy makers.
Objectively, it can be shown that this is exactly what is happening. The chart below shows that returns across all assets over the last 120 years have experienced both the best and worst extremes in performance just in the last year or so.

In Q1 2019 the variation in US government bonds relative to US equities was also “out of sample”. Government bond yields have never fallen this much, while the S&P 500 rallied this much.

Government bonds yields fell naturally as world growth collapsed to the lowest level since 2008 (see below). US stocks rallied as intervention and policy changes came to the rescue of the stock market.
It seems that as interventions and policy changes have begun to fail, they have to become increasingly more violent.
Failing Central Banks. Strategic Risk And Investment Plan Review Essential.
Today the market’s focus is heavily concentrated on the Federal Reserve’s every utterance and every possible interpretation.

Rightly so. The Federal Reserve has dominated markets ever since 2008.
“The bull market of the past decade since the Great Recession has been an unusual one: despite all of the economic damage that occurred during the global financial crisis and rising risks (including global debt rising by $75 trillion), it has been the longest bull market in history. The explanation for this paradox is simple: it’s not an organic bull market because the Fed and other central banks keep stepping in to prop up the market every time it stumbles. Though the Fed has two official mandates (maintaining stable consumer prices and maximizing employment), it has taken on the unofficial third mandate of supporting and boosting the stock market since the Great Recession.
The chart below shows how the Fed or other central banks have stepped in with more monetary stimulus (quantitative easing, promises to keep interest rates low, etc.) every time the S&P 500 has stumbled over the past decade:”

The deeper the central banks have gone into this “unofficial third mandate of supporting and boosting the stock market” the more trapped the central banks are, in what now could be described as the biggest US stock market bubble in history.
Here is a chart of the valuation metric that correlates most closely with actual subsequent long term US Equity market returns.

Currently, the 90 year track record of this measure, shown below, estimates the 12 year nominal expected return on the S&P 500 will be around MINUS 1%. Let’s call that a bubble.
Of course, that tells us very little about what the S&P 500 will do in the next year or so, but if you are considering a long term strategy beyond that then this is key information that should be considered
In addition to this long term risk, the world economy is now at its weakest since 2008. Not really much support for the highest US equity valuations in history.

This overvaluation has been well disguised as after tax earnings have been boosted by tax cuts, buybacks, and other adjustments. A cleaner view of core earnings comes from pre-tax earnings, which are broadly unchanged since 2012. No real “organic” support for US equities here.
