Mastering the timing of investment markets is a formidable challenge that demands unwavering commitment to a well-defined methodology. It entails navigating through risks, optimizing volatility, and steering clear of managers who adopt a reckless “spray and pray” approach. 

Today, allocators must carefully consider the current market cycle, strategically position their incentives, and strike the right balance between liquid and illiquid assets. By embracing this approach, they can shield themselves from the anguish of overallocating in underperforming asset classes.

Join Michael Oliver Weinberg as he engages in a captivating conversation with Paul C. Sohn, Chief Investment Officer at Mont Alto Capital, in the latest episode of the Improving Alpha podcast. Paul provides his front-row insight and expertise on what he has observed over the last 20 years in hedge fund investing, macro portfolio management, and the formation of his family office, Mont Alto Capital.

  • his background and what strategies he’s specifically leveraging to capitalize on ‘fat pitches’ in institutional investing.
  • his thesis on the Greek recovery trade, what Kyriakos Mitsotakis leadership means for the future of the country, and what the US could learn from his examples.
  • how his family’s timber business influenced Paul’s beliefs on ESG and why ESG in its current form is very similar to child brain thinking.
  • where is private equity allocations moving now that the wind in the sails has died down in comparison to the last decade of returns.
  • if commercial real estate will be a ‘whimper’ or a ‘bang’ in the coming years and does that create an opportunity for distressed buyers.
