Put five Fools in a room, ask them how they invest, and you'll probably get five different answers. Some like growth, others value, or small caps, or dividends, or, well, you get the picture.

Yet while our styles may differ, we all want excellent, engaged managers running the companies we own. We like it even more when these managers are also owners -- investors like you and me who, in trying times like these, are willing to buy as others sell. That's why I write this column weekly.

Bolting titanium to your portfolio
Few of us long-term investors have truly outstanding timing, especially yours truly. But I'm not alone. David Gardner recommended Titanium Metals to Stock Advisor subscribers recently and has seen the stock backslide by more than 30%. (The S&P is down just under 23% over the same period.)

The good news? Timing isn't all that important if your intent is to hold for at least three to five years, or, better still, longer. And there are few stocks our 115,000-strong Motley Fool CAPS community likes for the long haul more than Titanium Metals (Timet):

Bulls like David point to titanium's usefulness in commercial applications. Quoting from his original write-up:

Supremely corrosion-resistant and sporting the highest strength-to-weight ratio of any metal, titanium isn't just a key component of stratosphere-ready exoskeletons. It's a crucial commodity for the aerospace industry, where it's used to make aircraft frames, engines, and supports. It's also used in cars, prosthetic limbs, and deep-sea oil and gas drilling platforms.

Trouble is, Timet isn't the only company that extracts and processes titanium. So do Russia's VSMPO-Avisma, RTI International (NYSE:RTI), and Allegheny Technologies (NYSE:ATI). What's so special about Timet?

Insiders. Both Simmons brothers -- company chairman Harold and director Glenn -- have been buying in bulk. And it wasn't that long ago that board member and professional investor Terry Worrell was buying.

Also interesting is Timet's extremely strong capital position; debt accounts for less than 2% of total capital, according to Capital IQ. Neither Allegheny nor RTI can match that.

And it's a huge asset generally: With a credit crunch upon us, Timet is still able to fund growth via free cash flow -- $88 million worth over the trailing 12 months alone. That's far too rare right now. Thus, Timet, trading for a very reasonable seven times earnings, joins my ailing CAPS portfolio today.

Where's Walter?
Interestingly, the insiders seem to have been pretty prescient on this one. Three separate executives were selling above -- wait for it -- $80 per share in May. Now, one of them is buying: Chief Financial Officer Victor Patrick, at $40.55 a share. I'd like to see his peers join him before adding a position in CAPS, but history says it's worth adding Walter to my watch list.

There's your update. See you back here next week when we dig through more insider filings in search of the next home run stock.
