It's no surprise that stock investments in the nation's IRAs reached a peak in 2007, before the recession and the financial sector collapse. In 2007, IRA investors between the ages of 25 and 59 had more than 75 percent of their assets in stocks.
That fell dramatically in 2008, dropping to under 65 percent of all IRA assets. It's been rising in fits and starts since then, but even as of 2012, that figure was only up to 68.3 percent, according to the Investment Company Institute.
But now, IRA investors have 72.6 percent of their assets in stocks, the highest that figure has been since 2007. It looks like investors' confidence is almost all the way back to where it was before the meltdown.
