Sam Dickie, senior portfolio manager with Fisher Funds, said it looks like some investors are taking the Meridian and Contact money and putting it into other dividend-yielding stocks.
He said the rise in price of those energy stocks has been the story of the week.
The iShares Global Clean Energy exchange-traded fund has increased its issue of shares and has gone out and bought more stocks, including Meridian and Contact.
"These stocks now make up more than 10 per cent of the fund which has bought $850m worth of Meridian and Contact shares over the past three months.
"Renewable energy stocks are in vogue. How long this will last is anyone's guess," said Dickie.
