Why four and not one

Series IV earns the most of the four and falls the hardest, at 26.900%. Held together, the four fell 14.800% — because they do not fall at the same time. That is the only honest reason a set is worth more than its best member, and it is the reason the ladder exists at all.

This is for you if

  • You manage your own money and hold a brokerage account.
  • You have tried to time the market, and noticed the hard part was never picking — it was knowing when you were wrong.
  • You want a rule you did not have to invent.

It is not, if

  • You want stock tips, or the news explained.
  • You want to be told you will get rich.
  • You will not actually place the trade.
