Under TPA, an investor's job is no longer to fill asset class buckets. Instead, it's to generate knowledge on how any potential investment—be it a manager, ETF, or direct deal—adds value to the overall portfolio's objectives, forcing an apples-to-apples comparison of all opportunities.

The new approach to asset allocation treats private markets as an alternative to public stocks and bonds, not just a small add-on. This means integrating them directly into the core equity and debt portions of a portfolio to enhance returns and diversification.

Owning multiple stocks or ETFs does not create a genuinely diversified portfolio. True diversification involves owning assets that react differently to various economic conditions like inflation, recession, and liquidity shifts. This means spreading capital across productive equities, real assets, commodities, hard money like gold, and one's own earning power.

The firm CPC focuses its portfolio companies on mastering five core areas: people, systems, execution, product leadership, and customer intimacy. They believe strong financial results are an inevitable byproduct of winning these battles, not the primary goal itself. This operational focus dictates their capital allocation.

Simply "thinking long-term" is not enough. A genuine long-term approach requires three aligned components: 1) a long-term perspective, 2) an investment structure (like an open-ended fund) that doesn't force short-term decisions, and 3) a clear understanding of what "long-term" means (10 years vs. 50 years).

The first principle of portfolio construction is not asset allocation but personal conviction. Gardner argues investors achieve better returns when their portfolio is filled with companies they admire and believe in. This alignment creates the psychological fortitude needed to hold through volatility and let winners run.

Contrary to common belief, the Total Portfolio Approach (TPA) isn't about nimble trading. It's a framework that uses data to understand the risk of any investment relative to a simple reference portfolio (e.g., 70/30). This allows allocators to fund compelling opportunities flexibly, freed from rigid, pre-defined asset class silos.

A pure TPA system can alienate specialists hired for specific asset classes. A hybrid model, where a portion of capital is allocated to traditional buckets, allows organizations to retain deep expertise in areas like private equity while still gaining the benefits of a holistic TPA overlay on the rest.

Temasek's partnership philosophy prioritizes acquiring new capabilities over simple risk diversification. The fund actively seeks partners who possess specific skills it lacks for certain investment opportunities. This approach treats partnerships as a strategic tool for enhancing internal expertise rather than a purely financial mechanism for spreading risk.
