- What does BSPIX invest in?
- This fund operates as a "feeder" vehicle, allocating all of its capital into the Master Portfolio, which is managed by MIP.

Furthermore, the fund aims to mirror the S&P 500's weighting, meaning the proportion of its assets invested in any particular stock will closely correspond to that stock's representation within the broader index.
