Berkshire Hathaway is worth accumulating because its insurance float and $324.9B Treasury bill pile pay it to wait for an opportunity, so higher rates bring income and leverage over whoever runs out of cash first. It passes the Second Paycheck Test at unmatched scale, with $177.5B of float. Rate gains alone are small, about $642M after tax per quarter point, and GEICO's underwriting profit fell 45%. Management bought about $4.5B of stock near 1.4x book; at 1.48x, accumulate, don't chase. x.com x.com x.com x.com x.com x.com x.com x.com x.com x.comÂ
