Jennifer Wallace is a value investor. She learned her tradefrom a series of luminaries, studying under Bruce Greenwald at Columbia, before going to work for famed value investor Bob Bruce (who used to hang out with Warren Buffett).

Today she is the CIO of Summit Street Capital Management, and only invests in high quality companies with modest leverage when they are super cheap. This means she will often find stocks with issues that are hopefully temporary.

But she has found a winning formula, having delivered a 7.8x return to investors since 2009. Around a quarter of her investee companies have been acquired. She explains why, her rationale for having a 25-30 stock equally-weighted portfolio and why you should not befriend CEOs - "if you want a friend, get a dog”.
