Diversification

AI Analysis


The gist

The portfolio is mostly a single equity bet wrapped in a short-duration bond sleeve: six risk assets move together, and Short Treasury ETF (SHY) is doing the actual diversifying.

The numbers

  • Diversification ratio is 1.17 at 1Y and 1.13 incept, which sits around the 26th-36th percentile on the platform; that is modest diversification, not a portfolio with many independent engines.
  • Effective asset count is 4.6 of 7, but the cluster data says otherwise: one bond sleeve plus one equity cluster, which is the market’s way of saying “technically seven positions.”
  • The strongest internal correlations are high: iShares S&P SmallCap 600 Value ETF (IJS) and iShares S&P SmallCap 600 Growth ETF (IJT) at 0.95, and Vanguard Value ETF (VTV) with Vanguard Mega Cap ETF (VV) at 0.90.

The good

  • SHY’s -0.12 correlation to the portfolio and its 30% weight give the structure a real stabilizer.
  • Vanguard FTSE All-World ex-US ETF (VEU) and Vanguard Real Estate ETF (VNQ) at least introduce non-U.S. and real-asset exposure, which is more varied than a plain U.S. equity basket.

The bad

  • The equity sleeve is heavily self-referential: VTV, VV, IJT, and IJS all sit in one cluster, so the value/growth and large/small distinctions matter less than they look on paper.
  • VEU’s 0.93 portfolio correlation means foreign equities are behaving like another equity beta source, not a separate risk stream.
  • VNQ is the lone non-bond outlier, but at 0.74 portfolio correlation it is still mostly an equity cousin with a different costume.

The ugly

  • In an equity selloff driven by rates, earnings revisions, or recession, the cluster can compress further and leave SHY as the only meaningful offset.
  • If small-cap style spreads or value/growth spreads widen in a crisis, the portfolio does not own enough independent factor variation for that to matter much.
