FRANCOIS-ROCHON

Thirty years of 15% returns. The secret? Buy quality businesses and do nothing for as long as possible.

I am an engineer by training. I approach businesses the way an engineer approaches a bridge — I need to understand every load-bearing element.

Investing is both a science and an art. I named my firm after Monet's village because great investing, like great painting, requires patience and vision.

The hardest part of investing is doing nothing. The second hardest part is doing nothing when everyone else is panicking.

Portfolio turnover of under 10% means I spend 90% of my time thinking about whether I own the right businesses, not which ones to trade next.
