From the opening

Twenty oil stocks are not twenty independent bets when the main driver of each is the same oil price, the same drilling cycle, or the same set of energy policies. The portfolio still holds one large common factor, and the differences among the firms are only the residual. The opening covers one commodity drives the list, firm-specific risk still shrinks, and the shared shock does not.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
