Investing and risk

The investing sources here span seventy years and one shared premise: the investor's main problem is the investor. Graham gives the analytical frame, Housel the behavioural one, and the newer sources test both against markets that move faster than either author expected.

AskNex is independent of the authors and publishers it draws on. The books listed here are sources AskNex has read and mapped; the ideas are described in AskNex's words, never quoted, and reading the originals remains the deeper path.

Ideas that recur

The concepts the most books in this topic contribute to. Where several sources meet is where the arguments happen.

  1. 01

    Risk and uncertainty

    How people mis-estimate downside, and what survivable plans look like.

  2. 02

    Wealth vs income

    Income is what arrives; wealth is what is retained and put to work.

  3. 03

    Position sizing and drawdown

    Sizing each commitment so that no single loss can end the series.

  4. 04

    Margin of safety

    Deliberate slack between an estimate and a commitment, so being wrong is survivable.

  5. 05

    Conviction versus speculation

    Holding because of an argument with a margin of safety, as opposed to holding because the price moved.

  6. 06

    Time horizon

    The period a decision is judged over changes which decision is correct.

  7. 07

    Trading discipline

    Following a defined method through wins and losses without needing any single trade to be right.

  8. 08

    Compounding

    Small advantages repeated over long periods dominate large one-off gains.
