Since new Reserve Bank governor Adrian Orr started, he had indicated a stable platform for interest rates for consumers.
That would mean people with money to invest were more likely to seek out income-generating investments on the NZX than make bank deposits.
United States treasury bonds had risen above 3%, only to fall below the mark later in the week.
Five-year swaps were 2.7%, indicating a stabilisation of interest rates, Mr McIntyre said.
Uncertainty about the Labour-led Coalition Government, falling business confidence and the increase in cattle disease Mycoplasma bovis were all making people nervous.
''There is potential for harm to our dairy sector which could flow into lower exports. All of this can affect economic growth.''
Asked what was driving the rise in the NZX, Mr McIntyre said international investors were becoming more interested in New Zealand's renewable sector and companies like Meridian Energy were feeling the benefits of investor interest.
New Zealand's retirement sector was also attractive for overseas investors. The sector was well run, had good demographics for the next 15 to 20 years and was providing good returns, he said.
Some of the things which could turn the market downwards included a meltdown in China, rising interest rates in the US and an increase in New Zealand's wage inflation.
US interest rate moves were well signalled but higher oil prices would eventually feed into inflation, Mr McIntyre said.
New Zealand's low wage inflation had kept a lid on rising prices, keeping Consumer Price Index inflation - the official measure - below the Reserve Bank's 2% target.
US President Donald Trump doing something ''simply terrible'' might also cause a slump in markets.
However, he had already done some pretty bad things and markets had survived, Mr McIntyre said.
An all-out trade war with China or the European Union could be a catalyst for investors to start being wary, he said.
Leaders of the Group of Seven rich nations headed for a summit in Canada yesterday more divided than at any time in the group's 42-year history, as Mr Trump's ''America First'' policies risked causing a global trade war and deep diplomatic schisms.
In a bid to rebuild America's industry, Mr Trump has imposed hefty tariffs on steel and aluminum imports, including those from key G7 allies like Canada, Japan and the European Union.
French President Emmanuel Macron, who has invested in a warm personal relationship with Trump, said the other G7 nations - Britain, Canada, Germany, Italy and Japan, as well as France - should remain ''polite'' and productive, but warned that ''no leader is forever'', a sign that Europe would not surrender meekly to the US president.
Forsyth Barr broker Damian Foster said the latest reporting season ended on a slightly positive note as beats outweighed misses.
Revenue growth far outweighed expectations at 6.7%, operating profits fell by 1.9% against expectation of a 3.5% fall, and earnings per share growth came in at -6.3% against a forecast of -7.6%
Of the 21 companies to have reported, seven reported ahead of EPS expectations, six were in line and six were below expectations.
Given the small reporting season, Forsyth Barr had explored the wider market, identifying companies where share prices had outperformed or underperformed relative to changes to 2019 earnings forecasts, he said.
''We start our analysis by looking for potential outliers where share prices have outperformed or underperformed relative to changes in forecast earnings over the last three months.''
Companies appearing more expensive were: Arvida, Chorus, Fonterra, Investore, Mainfreight, PGG Wrightson, Restaurant Brands, Summerset, Tegal and Vista Group.
Those looking cheaper included: a2 Milk, Comvita, Michael Hill, Methven and Sky Network Television.
Mr Foster noted Australian ownership of New Zealand shares had soured slightly.
