First, in New Zealand and most other nations a significant part of economic growth derives from new and small businesses.
These tend to be under-represented on listed equity markets, which are typically dominated by large banks, utilities and multinationals.
Second, in today's highly integrated world, global rather than local conditions often matter more for a market's prospects.
New Zealand's equity market has been a top performer in the past year with increasing flows from foreign equity manager behemoths attracted to high-dividend-yielding stocks.
This has helped push up equity prices to levels that make our market appear quite expensive. From an integrated markets perspective, however, our market has simply enjoyed a period of catch-up.
Third, and perhaps most important, as with any asset price, expectations of future conditions matter more than what is happening today.
Asset returns since the GFC have been exceptionally high across bonds, equities, commercial and residential property.
This has partly been because global economic growth and inflation have been genuinely weak, and the slashing of rates by central banks in response has boosted asset prices higher. But it also reflects that the worst downside fears have failed to materialise.
Listening to the doomsayers may be entertaining, but following their investment advice is rarely wealth enhancing.
