IVE vs TSPI: 1% overlap
iShares S&P 500 Value ETF and TSP I Fund — shown via international proxy share 1.3% of their portfolios by weight — computed as Σ min(wA, wB) over every holding both funds own.

Where IVE and TSPI differ
Sector weights as a share of each fund, ordered by the size of the gap rather than the size of the sector — two funds that overlap heavily still usually diverge somewhere.
| Sector | IVE | TSPI | Δ |
|---|---|---|---|
| Unclassified | 0.0% | 9.1% | −9.1pp |
| Health Care | 12.5% | 5.3% | +7.2pp |

| Consumer Discretionary | 9.6% | 7.5% | +2.1pp |
Δ is IVE minus TSPI, in percentage points. Sector data is not published by every issuer, so “Unclassified” is a real category rather than a gap in the table.
What each fund holds alone
92.2% of IVE by weight, held in no part of TSPI.
95.7% of TSPI by weight, held in no part of IVE.
A large count with a small weight is the usual shape: the positions one fund adds are typically its smallest ones.
Concentration and cost

| Top 10 holdings | 23.7% | 16.3% |
| Positions held | 440 | 8,453 |

Cost is the expense ratio applied to $10,000; it excludes any brokerage commission, bid-ask spread or tax consequence. Figures are facts about the funds, not a suggestion about which to hold.
Frequently asked
How much do IVE and TSPI overlap?
IVE and TSPI overlap 1.3% by portfolio weight — largely distinct portfolios. They share 54 holdings. The figure comes from current issuer holdings files (IVE as of 2026-07-23, TSPI as of 2026-06-30).
How is the overlap between IVE and TSPI calculated?
As the sum of the smaller weight in each fund, over every holding both funds own: Σ min(wA, wB). If IVE holds a stock at 6% and TSPI holds the same stock at 4%, 4% counts as shared. The result is bounded between 0% and 100%, and it is computed after looking through any fund-of-funds to the underlying holdings.
Is it redundant to hold both IVE and TSPI?
That depends on your goals — we state facts, not advice. At 1.3% overlap, each fund still contributes meaningfully distinct exposure.
What does IVE own that TSPI doesn't?
IVE holds 440 positions and TSPI holds 8,453; 385 of IVE's positions don't appear in TSPI at all, and they are 92.2% of IVE by weight.
