Scientific and efficient portfolios.

Our investment philosophy is based on proven research from leading academics such as Markowitz, Sharpe, Malkiel, and Bogle. We refer to it as the evolution of investing and utilise the most efficient and time tested investments to help you meet your goals.

Here is an overview of the principles behind our philosophy:

  • Efficiency – taxes and charges taken out of your portfolio are not providing a return in your portfolio
  • Asset Allocation – the biggest driver of portfolio variance in the long run is asset allocation, not stock picking or market timing.
  • Diversification – a well diversified portfolio will provide smoother returns over time and create a better efficient frontier
  • Tax – contrary to what other investment managers tell you (or worse, don’t tell you), tax matters if you are an American living in the UK
  • Risk management – managing risk is more important than chasing returns – you need to keep what you’ve earned
  • Goals – assets need to conform to your goals, not the other way around.

Our CIO, Kristopher, is always happy to discuss and explain the Tanager Investment Philosophy.
