Famed money manager Peter Lynch gave us the inside scoop on how to look at insider transactions. Executives can sell their stock for any reason, he said, but they only buy for one: They think the price is going to go up!

Today, I've highlighted a handful of insiders who have made big purchases of their own company's stock in the past week. These aren't executives getting big chunks of shares from option grants. Rather, they're insiders putting their own money on the line, buying shares at market prices. I then paired that information with insights from the members of Motley Fool CAPS to see if they think the stock has the same prospects the insiders do.

Although following the lead of insiders can be profitable, we still recommend you do further due diligence to determine whether these stocks make a good addition to your own portfolio. So this isn't a list of stocks to buy, just the inside track on companies you might want to check out further.

A toy story
After reporting earnings results that showed profits were down 70% year over year, toymaker Hasbro peeled back about 10% from its recent highs. While Mattel (NYSE: MAT) also reported lower profits (down 33%), the difference between the outcomes is noteworthy.

Hasbro is no longer just a toy company. Like Mattel, it's able to sell toys based on popular movies, Mattel benefited from sales of merchandise tied to Toy Story 3, but in a very big departure, Hasbro is now a content company, too. It produces movies instead of just riding on their coattails, and it's now the joint owner of a TV channel aimed at kids. In many respects, Hasbro is moving closer to Disney (NYSE: DIS), and its results are no longer tied just to how well its toys sell -- although that remains a big part of the story -- they also depend on how well its movies do at the box office.

That was the key to Hasbro's results this quarter. Last year it had Transformers and G.I. Joe movies in theaters, which drove sales and profits higher. This quarter there was nothing. Going forward, investors need to keep one eye on movie receipts and another on retail shelf space. Hasbro will need to jealously guard its properties just as keenly as the most adept Monopoly player hoards Boardwalk.

For CAPS member mwlove, the toymaker has a depth of portfolio that will allow it to mine its brands for greater profits:

With movie tie-in products coming in droves in the summer of 2011, Hasbro has income generating machines warming up. Wait and see on the HUB, but the other products line ups are top-notch for the second half of 2011.

Profiting at the margins
With gold prices soaring, top-notch miners should excel even if their costs per ounce of gold run a little high. Newmont Mining ran into problems during the ramp-up of its Boddington mine in Australia last year and its costs per ounce ran up higher than expected. Agnico-Eagle Mines (NYSE: AEM) also suffered setbacks at its Meadowbank mine, which caused production costs to rise 20% over the year-ago period.

Particularly for Newmont, however, which also displays some fine copper reserves, the weakness its stock displayed recently can easily be surmounted. CAPS member shivan2418 sees some gloomy global prospects driving gold prices even higher:

dollar collapse
bankruptcy of several countries
gold is the way to go

A transforming event
Wells Fargo, along with US Bancorp (NYSE: USB), might be one of the best banks in the business, according to Warren Buffett, and Charlie Munger might think Wells has a top management team. But corporate governance watchdogs think the current slate of directors being nominated for the board leaves a lot to be desired.

Berkshire Hathaway's tag team duo gave a ringing endorsement to Wells Fargo at the recent annual meeting, but Glass Lewis and ISS Proxy Advisory Services both recommended voting against a number candidates up for election to the board of directors. In particular, three directors who served on Wachovia's board as it sunk to the brink of failure before being rescued by Wells, were singled out as poor choices.

I always hate betting against a company when the CFO is buying in, and it's hard to argue against Buffett & Cos. endorsement, but do you really want people who oversaw the destruction of a financial institution providing guidance to another banking giant?

CAPS All-Star Jordrok is willing to side with Buffett, but JimVanMeerten says Wells is giving off sell signals. Tell us on the Wells Fargo CAPS page into which camp you fall.
