LaurentBernutLaurent Bernut was a systematic short seller with Fidelity for 8 years. His mandate was to underperform the longest bear market in modern history: Japanese equities.

Prior to that, he worked in the Hedge Fund world for 5 years.

He now runs an automated Forex strategy and travels the world with his family.

In this episode we talk all about Short selling, creating shorting strategies, the challenges of implementation and how to manage risk. We also discuss the importance of exits, insights into Bear markets, autotrading Forex and why complexity is a form of laziness.

Top tips from this episode

Here are few of my favourite takeaways from the chat with Laurent this week:

  • Short selling – there were so many tips on building short strategies I couldn’t go through them all again but I found it interesting that Laurent says that if you can build a positive expectancy on the short side, the long side will be easy
  • The importance of exits – I really liked the quote ‘You can’t achieve superior performance simply by good entry’, which is an obvious statement but it’s also a good reminder on the important of exits and how they can impact trading results. There can often be too much focus on entries.

    Hi Andrew,

    Another great episode and I wanted to drill down on what Renault meant when he said, “The Sharpe Ratio is the right mathematical answer to the wrong question.”

    Could he possibly expound upon what he meant by this?

    Thank you.

    Warmly,

    Brian

    Hey really good episode here very informative and I love listening to a professionals take on the markets and short selling. I feel like if there is anything ive learned it when to get out of the market while short selling. I think most of the trades I make are shorts and that’s in forex, I don’t trade stocks yet. I feel like when the boat is to full on the downside there is always a reaction higher before getting back on the boat again.. I use Fibonacci levels of resistance to find these reaction levels. I find when you find and anchor price from lows to lows or even from highs to lows , as long as you can find the prices being respected it will help you indicate when to jump on and off the boat !! I am a new trader and haven’t made any money yet but am trading in demo and would love to learn more things like this!! keep em coming.

      Hey Travis, glad you enjoyed the episode with Laurent.

      Since you’re into trading Forex you should definitely take a listen to the episode with Andrea Unger, we talk about Forex in that one too.

      Cheers,
      Andrew.
