The most accurate play in each family

Each family's play whose calls went the right way most often, tested on 351 stocks since 2005, and what it says about NPCE now.

A call is right when the stock rose after an in call or fell after an out call. Trend plays are built to take many small losses for a few big wins, so their hit rates run lower; being right often isn't the same as making the most money. How we test a play.

If the market cracks: the storm test

How the storm test works
ExposureHigh6 of 10 points
  • Market swings1/3

  • Run-up0/2

  • It carries 3.7× as much debt as equity.
  • It operating profit doesn't cover its interest.

Past crashes, peak to low

NPCE−70%
S&P 500−25%
  • Beta0.94Moves about 0.9× as much as the S&P 500 week to week.
  • Downside capture290%In months the S&P 500 fell, this fell 290% as much on average.
  • Two-year change+92%Run-ups of 100%+ crashed 40% or more within two years about half the time (Greenwood, Shleifer & You).
  • From 52-week high−34%
  • Debt to equity3.67×
  • Interest cover−1.9×

A crash marks every stock down; debt decides which companies come through. The storm test scores both halves: how hard the stock swings with the market, and how much debt it carries into a downturn. It describes fragility; it does not predict a crash.
