Ranked exposures

▼ BRK.B Berkshire Hathaway — impact -75 · confidence medium · horizon immediate · 1st order
Berkshire Hathaway shares trade closer to book value as the leadership transition removes the key-man premium.
Chain: Buffett steps down as chairman of Berkshire → key-man allocation premium leaves the valuation → investors reprice the holding company on assets → price to book multiple drifts toward one
What would break the call: Abel announces a large buyback at current prices and the multiple holds above book.
▲ OXY Occidental Petroleum — impact +55 · confidence low · horizon quarters · 2nd order
Occidental gains takeover speculation because Abel controls Berkshire's twenty-eight percent stake and the cash to buy the remainder.
Chain: leadership change at Berkshire resets deal appetite → Abel controls a large Occidental equity stake → market prices odds of a full takeover → Occidental shares gain a control premium
What would break the call: Abel states publicly that Berkshire will not acquire the rest of Occidental.
▼ BRK.A Berkshire Hathaway Class A — impact -45 · confidence low · horizon quarters · 1st order
Buffett's continuing conversion and donation of Class A shares adds steady supply into a thin trading market.
Chain: Buffett continues converting Class A into Class B → converted shares flow to charitable foundations → foundations sell into a very thin market → supply overwhelms limited Class A demand
What would break the call: The estate slows conversions or Berkshire buys back Class A shares directly.
▼ KHC Kraft Heinz — impact -45 · confidence low · horizon quarters · 2nd order
Kraft Heinz faces a stake overhang because new leadership carries no attachment to a long underperforming position.

What would break the call: Berkshire reaffirms the Kraft Heinz stake as permanent in its next filing.

What would break the call: Markel reports adverse reserve development and the quality re-rating stalls.

What would break the call: Berkshire's next 13F shows the Apple stake stable or increased.
▼ DVA DaVita — impact -40 · confidence low · horizon quarters · 2nd order
