Friends,

There are lots of ways to succeed as an investor.

Between 1965 and today, an investment in Warren Buffett's Berkshire Hathaway has achieved 19.8% annual returns. He has done that primarily by focusing on valuation and economic moats.

Between 1977 and 1990, an investment in Fidelity's Magellan Fund -- under the direction of Peter Lynch -- jumped 29% per year. He accomplished that by focusing on the PEG Ratio -- which combines valuation with growth potential.

In 2007 Mark Spitznagel used ideas he had learned from his former business partner -- Nassim Taleb -- to start Universa Investments. The fund was formed with an odd goal: lose a small amount of money every day, but provide phenomenal returns when "Black Swans" hit. In March 2020 alone, the fund returned over 4,000%! The reasoning: the market misprices the significance of tail events -- and while they are rare, they can be extremely profitable.

At the entrance to Apollo's temple at Delphi (Greece), there's a dictum etched in stone: "γνῶθι σεαυτόν" -- or, Know Thyself.

While thousands of people are said to have visited the Oracle at Delphi for help with political decisions, military strategy, and religious queries, there's a reason this was what was inscribed on the entrance: it covers all areas of life.

The same can be said for investing.

Consider: Nassim Taleb didn't join Mark Spitznagel at Universa. It was because he knew it would be too painful to experience small losses every day, never knowing when that big payoff might come. He was fearful the stress of the business would cause a recurrence of cancer.

Instead, he quit the business entirely and focused on something else: writing an anthology of books that have all become best-sellers. He knew himself well enough to know what would work for him.

In the end, the strategy that will be most successful for you is the one you're most likely to stick with. There's no one-size-fits-all solution to this. Which means we can't provide any ready-made answers.

But it points you towards the important question: What kind of investing best suits you? Figure out the answer, and you've already done 50% of the hard work.
