WealthStack framework
Asymmetric opportunity
An opportunity is asymmetric when its plausible upside is large relative to the capital at risk. The payoff alone is not enough: the probability, time horizon, valuation, and position size all matter.
Start with the downside
Define what can go wrong before estimating an upside case. A position that could multiply may also lose most or all of its value. Decide how much of the total portfolio you could afford to lose on the thesis, and derive position size from that limit.
Potential payoff × probability is only a starting point. The assumptions and the cost of being wrong determine whether the opportunity belongs in a portfolio.
Four questions to ask
What breaks?
Estimate permanent loss, dilution, liquidity needs, and the conditions that would invalidate the thesis.
How long?
A strong thesis can still take years. Match the holding period to capital you can leave invested.
What is assumed?
Separate a promising business or asset from the price you are being asked to pay for it.
How much risk?
Choose a position size that lets the rest of the plan survive if this idea fails.
What would change your mind?
Write the evidence that would lead you to trim, exit, or add before emotions take over.
A decision checklist
- Write the thesis in one paragraph and name the catalyst.
- Describe a base case, a favorable case, and a loss case with explicit assumptions.
- Estimate the maximum portfolio impact if the position goes to zero.
- Compare the opportunity with simpler alternatives and with holding cash.
- Set review dates and observable conditions for changing the thesis.
