There’s a reason we adhere to our investment disciplines at Brandes. We have no control over markets or the actions of others. We can, however, control our own behavior. Our investment disciplines provide a carefully thought-out framework for action, whether markets are calm or in a frenzy. In our view, long-term success is not about “beating others,” it’s about helping our clients pursue their investment goals. And an essential aspect of that is self control.
