Read more on the length of the high growth period

Since
it is not growth that creates value but excess returns, this
question can really be framed as: "How long will excess returns
continue?" Since excess returns are conditioned on the existence
of barriers of entry, the larger and more sustainable the barriers
to entry in a business, the longer the high growth/excess return
period can last. There are other pragmatic considerations. As
firms get larger and acquire larger market shares, there is a
limit on how much longer they can continue to grow at rates higher
than the economy. Hence, a firm might find its growth tapering
off even before the excess returns go to zero. |
