It gets its exposure synthetically, through derivatives such as swaps and futures rather than by owning the underlying shares, so there is no conventional top-10 equity holdings list. See the description above for what SPIB actually tracks and how that exposure is built.
How do I invest in SPIB?
There are three common ways to get SPIB exposure. Buy shares (or fractional shares) of SPIB directly at any major broker that lists it. Hold it as a core position and layer more concentrated ideas on top. Or build it into a thematic portfolio in Walnut, so SPIB sits alongside other holdings that express the same thesis, with target weights you can rebalance toward. SPIB trades like a stock during market hours, so you buy it the same way you would any listed share.
