I won't sugarcoat it: Investors are nuts.

And not just the guys on Wall Street. I mean you and me. We're all nuts, and I'll prove it.

If you liked it at $60 ...
You know the shtick. "If you liked Sirius Satellite Radio (NASDAQ:SIRI) at $60, you gotta love it at $30." That was New Year's Day 2001. Two years later, you'd lost another 90% to a buck a share.

And Sirius wasn't alone. As you'll see in the table below, it was the same story for Qualcomm (NASDAQ:QCOM) and Intel (NASDAQ:INTC). Pain. Could the exact same thing happen today? Sure. Will it happen today? Who knows?

Either way, you'd be nuts to ignore the lessons learned from the tech crash, right? Not so fast. Here's why I'm getting greedy instead.

You probably should own stocks
I have to own stocks. I'm about as likely to switch to bonds and cash as I am to take up competitive bridge -- at least for the next 20 years. At my age, I just don't see any other way around it. And here's the catch for folks like us.

If we want to own stocks, we have to buy stocks. That is, unless you were clever enough to borrow against your future wages and overstuff your portfolio at the bottom in 2003. Otherwise, to be a stock investor, we have to keep buying stocks, right?

So, could we wait out this volatility? Sure, but what exactly are we waiting for -- some sort of all-clear signal? So we can miss the next bounce and pay more later? That's nutty. I can't tell you how today's stock prices will look relative to tomorrow's -- just that stocks are a better deal today than when we loved them last October.

How to catch a falling knife
OK, it's time I showed you that table. But before I do, I warn you -- it's scary. Scary enough to prevent you from having gotten burned in 2001? Yes, but it's even scarier for another reason.



Jan. 2001

Subsequent Fall to Bottom













Broadcom (NASDAQ:BRCM)




Prices are split-adjusted.

You read that right. Even after their stomach-turning initial plunges, every one of those former highfliers fell an additional 56% to 95% between January 2001 and their respective bottoms somewhere in 2002 or early 2003. I told you it was grim.

Now it gets really scary
If I could have showed you that table in March 2000, I might have spared you some pain. But what about when the market plunged 39% in 12 days back in Oct. 1987? Or when stocks "cratered" in 1991 ... or the dozens of other times stocks have pulled back 20% or more? You see where I'm going with this, right?

Not only would that one table have kept you from picking up some terrific bargains over the years, it could have kept you on the sidelines for the entire bull market, looking on as everybody around you got wealthy. And you'd probably still be out of the market now. If you ask me, that's worse than trying to catch a thousand falling knives.

So, where are we now?
I honestly don't know. Investors are skittish. But this doesn't feel like March 2000. Remember, every stock in the table we just saw ran up tenfold before heading south. We didn't know for certain we were in a bubble then, but we did know that stocks, especially tech stocks, were more expensive than they'd ever been before.

Is that the case today? I don't think so. Not even for the strong smaller businesses Bill Mann is sharing with members of his Motley Fool Hidden Gems newsletter service. True, 20 of those picks have doubled in value or more, including two I'm about to show you. But that's strong performance, not bubblicious -- especially given the lack of institutional funds parked in these stocks.

It is, however, enough to make you feel like you've missed the boat. I know I sure did. But the past few months, even the best of these Hidden Gems have pulled back, giving us a second chance to buy them cheap. Heading into October, don't be surprised if we get more chances -- be ready.

I'll continue to buy on weakness
(NASDAQ:NUAN), a company that develops speech recognition and transcription software, for example, has trended lower since May, though it's still up more than 100% for Hidden Gems members.

Meanwhile, my trip to Beijing got me even more excited about Chinese travel agent Ctrip.com (NASDAQ:CTRP), especially as China stocks have gotten downright cheap. A three-time recommendation, Ctrip is up more than 175% since I heard about it in Hidden Gems.

In fact, I have my eye on the Hidden Gems scorecard top to bottom. But that doesn't mean stocks can't go lower from here. A lot of folks think they will. Then again, a lot of folks always think stocks are going lower. Which is strange, given that the long-term trend has always been higher. That's why I say we have to own stocks.

Moreover, while I can't predict where the markets are headed near-term, it's certain that the stocks of the world's best companies will always head higher over the long haul -- no matter what happens to the "market." For the life of me, I can't see why we wouldn't want to buy them when they're on sale.

Finally, a word of caution
That table I showed you earlier is real, and it represents a world of hurt for investors. The lesson, however, isn't that you should avoid stocks. It's that you have to be selective. There's no shame in starting out with a low-cost exchange-traded fund (ETF) -- I own two small-cap ETFs myself.

But I know something better. Bill Mann and the team at Hidden Gems are bargain-hunting on your behalf. This month, they give you their two new top ideas, as usual. But they also rank their five favorite small caps for new money right now.
