This is how Obama could have made you rich

Donald Trump weighed in with his views on stocks this week, bringing back memories of an epic market prediction made by Barack Obama seven years ago.

Less than two months after taking office - on March 3, 2009 - the US President said the sharemarket was starting to look attractive.

It was a brave move as equities were still being pummelled by the Global Financial Crisis.

Obama said price-to-earnings ratios (a measure of how cheap or expensive stocks are) were reaching the point were buying equities was "potentially a good deal if you've got a long-term perspective on it".

How correct he was. Obama managed to achieve the holy grail of stock predictions - he called the bottom of the market.

Wall Street's S&P 500 sharemarket index bottomed out at 676.5 on March 9, 2009.

Since then - buoyed by years of low interest rates and other monetary stimulus - it has gained 200 per cent.

If you put $100,000 into an exchange-traded fund that tracks the S&P 500 a few days after Obama's call, it would have grown to around $300,000 by today.

Trump, meanwhile, reckons it's time to sell.

The Republican presidential nominee told Fox Business that he'd "got out" of stocks, which were only continuing to rally because of "free money" - a reference to low and negative interest rates in many part of the world.

Trump warned that shares were overvalued and "very scary scenarios" lie ahead for investors.

However, he added that equity markets will apparently "go great" if he gets elected in November.

New Zealand's S&P/NZX 50 share index has gained over 15 per cent this year and roughly 200 per cent since March 2009.
