The Tweedy Browne Global Value Fund, an investment advisory and fund management firm dedicated to the principles of Benjamin Graham and David Dodd, has a quarter-over-quarter turnover rate of 3% - which, in a portfolio that has nearly 100 stocks, means an approximate turnover of three stocks in a quarter. And that is precisely what Tweedy Browne did in the first quarter of 2015 - it sold its stakes in three companies and bought stakes in three new ones.
