“Leaving the question of price aside, the best business to own
is one that over an extended period can employ large amounts of
incremental capital at very high rates of return. The worst
business to own is one that must, or will, do the opposite - that
is, consistently employ ever-greater amounts of capital at very low
rates of return. Unfortunately, the first type of business is very
hard to find: Most high-return businesses need relatively little
capital. Shareholders of such a business usually will benefit if
it pays out most of its earnings in dividends or makes significant
stock repurchases.”
