Fifteen funds have already dropped a colossal 40% this year -- a staggering sum adding up to staggering losses for individuals. You've got all the usual suspects in the list:

Amerindo

,

Berkshire

,

Pro

,

Rydex

,

Firsthand

,

Van Wagoner

. Each one has a fund that has simply been terrible, horrible, vile and caustic to investors' hard-earned dollars.

I'm sure these funds are able to put a good face on it all. Most of them are probably saying, "Send me more money, as it can only get better."

You do what you want with them. You know what I think you should do. You've heard it from me so much that you'll think I'm just being a crank.

Invariably, the people with money in these funds say to themselves, "The damage is already so severe, I guess I'd better hold on." I know I spoke with someone last week who has been absolutely trashed by the

Putnam OTC Emerging Growth

fund, who feels like that. "Lost so much, who cares at this point?"

You know by now my thinking about that, too: False construct. All money matters; save what you can. That, however, is not why I write. I write because these funds tend not to be that big any more and so can't hurt as many people as they used to.

But that's not the case with the

(JAVLX)

Janus Twenty fund. This is a huge fund with huge losses -- down 19% already this year -- and I think it's going to lose far more than that before this blood-letting is over.

Nobody likes to attack Janus. Big advertising budget. Mainstay of the industry. Wounded juggernaut. Shouldn't be kicked when it's down. Etc. I know I've been a big supporter of Janus in times past. I liked their long-term style. My family has some money with them.

Now, though, I'm telling my family get out of Janus Twenty. Enough is enough. I don't want to wait until this fund is down 40% and have people asking me, "Why didn't you tell us to get out when there was still something left?" So I'm saying it now. These folks have taken their eye off the ball. Maybe one day they'll get it back; maybe they won't.

Look, I'm a pro. I have managed other people's money for two decades. Everybody is entitled to one bad year. But Janus is now knee-deep into another bad one. That's inexcusable. Time to take the money back and find someone who's doing a better job.

This year is shaping up to be another tough one for these technology-riddled funds. I've been adamant about blasting the stocks but have let the likes of Landis and Janus off with kid gloves. They've gotten a blank check from most journalists who write about personal finance.

They don't deserve one.

It's time for them to go from our portfolios before they destroy more of our hard-earned money.

I wish it weren't so. But somebody has to say it. Might as well be me. I'm not owned by these folks. And I know better.

So I have

no excuse

for not speaking out about what I know is the right thing to do to preserve your capital.

There. I feel better already. So will you when you make the move.
