The blunders we make with retirement accounts

According to a new paper, Americans commit a series of blunders with their retirement accounts. Author Jacob Hale Russell of Stanford Law School says that the flubs are not entirely our fault.

"Over the past four decades, the American retirement system has dramatically shifted risk onto the individual worker," Russell says. Whereas in the past, professional investment management committees were tasked with making complicated financial decisions, today the burden has shifted to individuals, and the results have not been good.

Retirement investors consistently make the following blunders:

Not allocating retirement accounts and leaving money in cash or

low-interest money-market funds, where it will decline relative to inflation.

Leaving a job, cashing out plan assets and paying a tax penalty, instead of rolling over the funds into another retirement account.

Choosing high-fee funds.

Failing to diversify and

over-investing in employer stock.

Not rebalancing on a periodic basis.

Overtrading individual securities.

Failing to take advantage of employer-matching programs for contributions.

With all of the literature that accompanies retirement plan enrollment, why do retirement savers continue to blow it? The author posits that people are simply overwhelmed by the decisions that they need to make. The policy response has been to use behavior economics to "nudge" retirement plan participants into making better decisions.

"Soft paternalism" or "libertarian paternalism" presents choices to -- individuals in a way that "encourages them to make better choices." The best example was the 2006 enactment of the Pension Protection Act, which allowed companies to automatically enroll employees, who could then choose to opt out of 401(k) plans. Participation has jumped for those companies who nudged employees into retirement plans.

That's the good news. However, other efforts have not been as effective. So what should be done? Russell encourages policymakers to take a big picture approach and ask: What purpose do we want 401(k)s to serve? Russell notes that there are often conflicts of interest that can lead investors down the wrong path, which is why he advocates regulating the quality and fee structure of the funds that serve as default investment options.

Until a wholesale review and upgrade to retirement plans occurs, here are some tips that should help improve your retirement plan results:

Put your 401(k) plan

on autopilot

Many plans offer the opportunity to automatically increase annual contributions. Have the plan add 1 or 2 percent each year in order to maximize your contributions over time. Additionally, plans also can be set to auto-rebalance your allocation on a periodic basis (quarterly, biannually or annually). Using this feature can help take emotions out of the investment process.

Diversify your holdings

You know that you shouldn't put too many eggs in one basket. But some participants don't realize how much overlap they may have among their retirement funds. It's far more important to diversify among asset classes (stocks, bonds, commodities and cash) than in the total number of funds. If your company stock is an option in your plan, limit your exposure to 5 percent of your holdings.

Choose index funds,

when possible

One way to increase your return without risk is to reduce the cost of investing. If your plan offers index funds, you may be able to save for retirement at a fraction of the cost of managed funds. If your plan is filled with expensive funds, gather your co-workers and lobby your boss to add low-cost index funds to your plan.

Beware pre-retirement withdrawals

During the recession, many were forced to take withdrawals from their retirement accounts to survive. But many workers still dip into retirement funds to fund everything from mortgages to credit cards and other bills. While the IRS does allow for hardship withdrawals in certain instances, pulling money from retirement accounts should be a last resort, due to potential fees and tax implications.
