There are few "gimmes" in investing. But today, I have advice that will both save and make you money.

First, some background
Half of all American households own equities, according to data from the Investment Company Institute (ICI). Roughly 90% of those equity owners invest in stock mutual funds (only about 50% own individual stocks).

If you or anyone you know is included in this group, listen up: You're probably paying too much to invest.

Just say no
How so? Most mutual funds sold through advisors are "load" funds, and according to the ICI, "Professional financial advisors are the main conduit to equity ownership outside employer plans."

A load fund has a sales charge levied by an intermediary -- a broker, financial planner, or advisor. In theory, the sales load reimburses the intermediary for advice and expertise.

So here's what we know: Huge numbers of Americans own funds; the "main conduit" to buy them outside an employer plan is through advisors; advisors charge sales loads ...

... and sales loads all but guarantee poor performance.

Most obviously, the load takes a slice of your assets off the top (or the bottom, in a back-end sales load). Consider John Hancock Technology:

Representative holdings

Microsoft (NASDAQ:MSFT)
Symantec (NASDAQ:SYMC)
Harris (NYSE:HRS)

Load (front-end)


Expense ratio


5-year returns vs. S&P 500

(6.64) percentage points

The math is straightforward: If you invested $5,000 in this fund, your actual stake would be just $4,750 ($5,000 minus 5%). (Seems harsh, given all the no-load choices that also have major stakes in Microsoft, Intel, and EMC.)

This information would've been useful -- yesterday
If you're already invested in a load fund and have absorbed the 5% ding, don't tune out. Your news is about to get a whole lot worse.

It turns out that load funds consistently underperform no-load funds, even when you back out fees.

That's what Tim Hanson and I found in our survey of the best funds of the past decade. Of the top-performing funds, 76% charged no load.

Academic research drives the point home even more: In 1998, Professor Craig Israelsen found that "even after ignoring the impact of loads, no-load funds had, on average, significantly higher returns."

Five years later, in Financial Planning Magazine, Israelsen wrote about a different time frame. The result was the same: No-load funds were superior to load funds.

A pattern is developing
Israelsen also shattered the rationale given by load-fund shops for the load funds they sell:

The party line being that -- over time -- a lower expense ratio partly, or perhaps fully, offsets the impact of a front or deferred load. [But] no-load funds ... had expense ratios which, on average, were about 37 basis points lower than the average load fund. ... Thus, the lower cost structure of no-load funds was only partly responsible for their superior performance.

So load mutual funds not only cost you more in fees, they cost you more in lost returns!

There's only one conclusion: Don't touch them with a 10-foot pole.
