SUB holdings

Computed by this site from the fund's SEC Form N-PORT filing; what the measure does not tell you · every fund in one table · hold it with other funds? X-ray the mix. Pricing: 0.59% at a quoted market price (level 1), one issuer country.

The largest line in SUB's filing is not a stock but BlackRock Liquidity MuniCash Funds: Institutional Shares, a short-term position at 0.59% of net assets. Ten companies are 3.11% of the fund; the other 2,907 share the rest. Among the 192 bond funds measured here, SUB behaves like 1283.4 holdings against a median of 236.4 — 5.4 times the median.
