Government officials often avoid conflicts between professional obligations and personal finances by divesting company stocks from their portfolios. So it comes as a surprise that, along with the standard mutual funds, Treasury Secretary Timothy Geithner owns a small amount of stock in yoga clothing retailer Lululemon...Turns out, he purchased less than $1,000 worth of shares a few years ago to teach his two children about the stock market, press aide Steve Adamske says. Geithner picked the company partly because of his now college-age daughter's interest in yoga—and as a hedge against her frequent Lululemon purchases, Adamske says. Additionally, Geithner owns $1,000 to $15,000 worth of IBM (IBM) stock, which he inherited. [BusinessWeek]
