As of its 25.9-year track record, its top holdings—such as Bloom Energy <span class="ticker">(NYSE:BE)</span>, Credo Technology Group<span class="ticker">(NASDAQ:CRDO)</span>, and Fabrinet <span class="ticker">(NYSE:FN)</span>—each make up less than 1.5% of the fund, resulting in a highly diversified mix.</p><p>VOO, in contrast, is concentrated in large-cap names and heavily tilted toward technology, with its three largest holdings—Nvidia <span class="ticker">(NASDAQ:NVDA)</span>, Apple <span class="ticker">(NASDAQ:AAPL)</span>, and Microsoft <span class="ticker">(NASDAQ:MSFT)</span>—together commanding nearly 20% of the portfolio.

VOO tracks the S&amp;P 500 — America's 500 largest companies — and now holds roughly $1.4 trillion in assets, making it the largest ETF in the world. IWM tracks the Russell 2000, the most widely followed small-cap index, with around $72 billion in assets and a 25-year track record.</p><p>They are less competitors than complements. VOO is heavily concentrated in technology and megacap names, with Nvidia, Apple, and Microsoft carrying significant weight. IWM spreads its 2,000 holdings across a far more balanced mix of healthcare, industrials, financials, and technology with no single sector above 18%.</p><p>The trade-off is straightforward. IWM offers exposure to smaller, faster-growing companies with more room to run, but with meaningfully more volatility and a higher fee. VOO charges a fraction of what IWM costs and delivers steadier, more predictable returns anchored by the largest, most established businesses in America.</p><h2>Should you buy stock in iShares Trust - iShares Russell 2000 ETF right now?</h2>
