Risk vs. Reward: Your Margin of Safety is Razor-Thin

The market’s over-reliance on a few giants is skewing risk-reward dynamics, squeezing your margin of safety to a razor-thin line. High valuations, shrinking diversification, and misplaced capital challenge investors to rethink conventional strategies.


Risk.

It is the crucial and unavoidable half of the investment scale.

As investors, we are first and foremost risk managers, because the law of large numbers applies. When you lose 10%, you need to earn 11% to break even. Once you move towards a 30% loss, the point of no return, the problem moves exponentially against you. Losing 50%, for example, mirrors the famous 100% profit required to break even.
