You guys never cease to amaze me.
Was I a little rough? Yes. Did I bash the mutual fund industry? Sure. Did I expect a few comments and uppity emails? Of course, but not this.
Feeling a little lost?
Don't worry -- here's a quick summary. A few months back, I proposed a little experiment I thought you’d enjoy. It was a bogus mutual fund made up of just three stocks, each bought in January 1990 and sold 10 years later.
For my three stocks, I chose Best Buy
The idea was to show how a modest $10,000 investment could have ballooned to $422,563 in just 10 short years. But that wasn’t the amazing part. For more details, check out "Don't Invest Another Penny." But come back, because this is where it gets good.
You see, there was a catch. Over the years, you'd have paid your mutual fund manager some $20,000 in fees, and surrendered nearly $58,000 in lost profits (money you didn’t earn on those fees). Instead of $422,000, you'd be sitting on … well, a lot less.
So, you hate me, right?
Of course you do, but I thought you'd take the funds' side. I thought you'd point out that nobody could pick just those three stocks, much less time the market so perfectly.
In other words, I thought you'd say that my $78,000 blood money is a gross exaggeration. Just wait until you hear what you really said.
Apparently, you're OK with me comparing the fund industry to an IRS on steroids. You took me to task for understating the case -- for trivializing the real cost to you as an investor, at least on a percentage basis.
And guess what? You're right. John Bogle -- the founder of Vanguard Funds -- makes the case bluntly in his book, The Battle for the Soul of Capitalism. Bogle shows how you don't need blowout returns (like in my three-stock example) to make the case against mutual funds ... you need time. Here's why.
Beware the "tyranny of compounding"
As it turns out, financial "intermediation" costs would have eaten up just 19% of your total returns ($78,000 out of $412,562) in my example. That sounded like a lot to me, but apparently not to Bogle -- and to some of you, either. In fact, for most of us, it will be worse.
For one thing, you won't be making 4,126% every 10 years, like in my bogus example. That's because for every stock rocket like Yahoo!
And even when your manager does catch lightning in a bottle, he or she will buy and sell too often, and at the wrong times. That's why Vanguard's Bogle thinks you'll earn less than "average" -- 8.5% per year by his estimate. Plus, you won't invest for 10 years, but more likely 25, 30, or even 45 years or more. Well, brace yourself, because this thing really gets ugly.
That'll be 80% off the top, sir
According to Bogle, if you invest for 45 years at his expected market return of 8.5% per year, "intermediation" costs can steal up to 80% of your rightful profits. You read that right. Not a mere 19%, like in my ridiculous little scenario, but as much as a full 80%. Ouch.
For one thing, Bogle uses a more aggressive 2.5% for intermediation costs. That's because he goes beyond reported "management fees" and includes taxes, transactions, and timing costs. And given that Bogle founded Vanguard, the most trusted mutual fund company in the world, I'm inclined to believe him.
More importantly, Bogle realizes that the more realistic your returns, the more deadly that 2.5% becomes, especially when compounded over the years. In other words, costs kill when your portfolio keeps doubling every six months. But when it doubles every 10 years or so, costs can really wipe you out.
What you can do about it
Frankly, I don't share Bogle's outlook for stocks. I think we'll do better from here, especially given the severity of the recent pullback. But even if we make three times as much as Bogle expects, we'll fork over well more than $100,000 in intermediation costs every 20 years.
If you resent that, here's a solution a lot of folks are considering: Start managing your own investments. You don’t have to jump in all at once, and you don't have to dump all your funds right away. But you can see how important it is that you give it some thought. Even so, you will need a few great stocks to get started -- and a little support.
