**Short answer:**
“iShares Core” is BlackRock’s line of **low-cost, broad‑market ETFs** designed to be the *foundation* of a long‑term portfolio (buy‑and‑hold, core allocation), not niche/short‑term trading tools.
---
## 1. What is iShares Core?
- **Goal:** Provide simple, cheap building blocks for:
- broad stock markets (US, international, EM),
- broad bond markets (aggregate, total bond).
- **Typical features:**
- Very **low expense ratios** vs. active funds.
- Track **major, diversified indexes** (S&P 500, MSCI, Aggregate Bond, etc.).
- High liquidity and large AUM (easy to enter/exit).
If an ETF’s full name starts with **“iShares Core …”**, it’s meant as a *core holding*.

## 3. How people typically use iShares Core
A common approach is a **“core–satellite”** structure:
- **Core (70–90%)**
A few iShares Core ETFs to get cheap, diversified exposure:
- US stock: IVV or ITOT
- International stock: IXUS / IEFA + IEMG
- Bonds: AGG or IUSB
- **Satellite (10–30%)**
More “aggressive” or “thematic” iShares ETFs (e.g. sectors, factors, themes) stacked around the core to try for extra return or specific views.

If you tell me:
- your **risk level** (conservative / balanced / aggressive),
- and whether you prefer **simple 2–3 fund** setup or don’t mind more positions,
I can sketch a concrete iShares Core portfolio example (with % weights) tailored to you.
