Rating Bankrate
I'm optimistic about the market. Crazy? Perhaps. It's likely my numbers aren't better than yours. Overall this year, the Beyers family portfolio was down 6.4% through yesterday. The good news: That easily bests the 15.2% hit the S&P 500 has taken. The bad: Down is down, and there's little consolation in knowing you're losing less than the index. So why am I optimistic? Like me, insiders are buying.

Our Rule Breakers stocks, in particular, are attracting stock shoppers. Witness the insiders at Sigma Designs (NASDAQ:SIGM). Last week, they spent $14,400 on shares of the beleaguered maker of chips for digital video, including Blu-ray.

But Sigma gets five stars at Motley Fool CAPS. Bankrate -- a recommendation of Rule Breakers -- isn't so fortunate. Those in our 110,000-strong CAPS community who have rated the stock give it just two stars:

Insiders disagree. Chief Financial Officer Edward Dimaria bought 2,500 shares on Friday. Board member Peter Morse followed on Monday, acquiring 10,000 shares at $25.56 apiece. Interestingly, Morse was a seller at just less than $50 a share in November.

My guess is that he's buying now because he senses a bargain. If so, he's not alone. Top mutual fund investors such as Ron Baron of Baron Growth (BGRFX) and Jason Votruba of UMB Scout Small Cap (UMBHX) also have meaningful positions in the stock. Perhaps it's time to join them.

A buying twist that a contortionist would love
MSCI Barra is, in some ways, like The Motley Fool; it's an information provider for investors. Most of its clients, however, are institutions such as mutual funds.

What's interesting here is that there's a high volume of concurrent buying and selling at MSCI Barra. CEO Henry Fernandez and Chief Operating Officer David Brierwood were buying last week. Business development head Gary Retelny was selling at the same time. Buys outstripped sells by $2.8 million. Nevertheless, I'm rarely excited to see the lead sales guy selling.

What's more, Morgan Stanley (NYSE:MS), the majority holder of MSCI Barra stock, announced two weeks ago -- before the buying -- that it would sell 23 million shares. We now know that its offering price is $32 per stub, roughly equal to the prices insiders are paying (and getting).

So is the action bullish, or bearish? For me, it's too early to call. Continue watching this stock; if insiders continue to buy, consider following. If not, well ... you know the answer.

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.
