As I muse about the recent news that one of the largest investment banks in the world, JPMorgan Chase, was able to foster a work environment in which employees were able to engage in spurious trading strategies that cost the company a cool $2 billion in losses, I'm struck by the contrast to how our analysts and subscribers define the idea of "success" in the markets. Instead of trying to make a fast buck, we're content to let time work for us, not against us, with a long-term mentality that focuses on identifying the underlying attributes that define a "quality" stock.

We don't get wrapped up in complicated securities or risky strategies. We're often calm when Wall Street is panicky. We have faith in the capitalist system in which companies that deliver profits to shareholders are rewarded with increasing share prices, and don't try to "game" the system. And while our stock picks don't end up in the plus column every single year, we have bested the overall market averages with an unbeaten track record among investing newsletters. And in that you should take comfort.

Now, on to the June 2012 issue. We feature three companies that are familiar to IAS subscribers. The first is a midsized medical instruments maker that's no sleeper stock. The second is a midsized industrial company in the business outsourcing field. Our third selection is a mega-cap behemoth in the data storage business.

We are recommending the sale of two companies in this issue, as well. Saying goodbye to stocks isn't always easy, but is often necessary when those companies don't live up to expectations, as is the case with one stock in this issue. In the other instance, a takeover bid has been made that's too good to pass by, so we'll take the cash now and find new opportunities in which to invest.

Go forth in your quest for winning stocks with the Investor Advisory Service's proven formula: Seek out quality companies for your portfolio like those in this (and every) issue of IAS. Be patient but firm in your oversight of those stocks. And enjoy the resultant investing success.
