TWO BETS
When Uncertainty Pays You
Cap your downside, leave your upside open, and the world's volatility stops taxing you and starts paying you. The only question left is the shape of the payoff, not the odds.
JENSEN
A wider spread lifts the average
This is convexity in one line. Options desks have priced the same fact since 1973 and named it vega: value climbs as volatility climbs.
- Jensen, 1906: the average of outcomes beats the outcome of the average
- Scherer & Harhoff: the top tenth of cases carried 48 to 93 percent of returns
- Black-Scholes, 1973: option value rises with volatility, called vega
Read the shape, not the odds
Two questions remain: the most you can lose, the most you can gain. This is convexity at work, swapping the owner's question from probability to geometry; the shape may already sit in a position you hold, a shadow option.
THE BARBELL
Safe mass, wild slice, no middle
- 01Park the bulk in safety
- 02Cut a slice you can lose entirely
- 03Scatter it across many open-ended bets
- 04Leave the fragile middle empty
AFFORDABLE LOSS
Sized by what you can lose
- A written-off stake, not a forecast return
- Survive the total loss of the attempt
- No hidden guarantee: the floor must hold
Affordable loss is the floor under the hockey stick. Cut it away with a guarantee, a reputation, or a partner's veto, and the payoff stops being convex.
IT NEEDS THE FOG
Risk you can price, uncertainty you cannot
- Risk: a known distribution, like a die
- Uncertainty: no reference class, genuinely new
- Convexity banks what no model can fold in
Knightian uncertainty is the tail a learning machine has nothing to learn from. Convexity needs the unknowable to stay unknowable, and a machine honest enough to say so.
BRING A VERIFIER
A cheap yes or no against hard truth
- Proof, measurement, registry entry, expiry date
- A verifier turns search into generate-and-sift
- No verifier, and the candidates are just noise
A bet pays only inside verifiable space. You collect only on a wager you can afford to verify.
SEEN FIRST
An option no one notices never existed
Bowman & Hurry: shadow options accrue as unbought by-products
These are shadow options. A recognition engine goes after the real bottleneck, because uncertainty can only pay you if you noticed the position you held.
