Broad Tech Exposure vs. Generative AI: Is VGT or CHAT a Better Option for Investors?

Roundhill’s actively managed Generative AI & Technology ETF (CHAT) has materially outpaced Vanguard’s passive Information Technology ETF (VGT) over the past year (52.11% vs. 23.06% as of Dec. 11, 2025) but comes with a much higher expense ratio (0.75% vs. 0.09%), far smaller AUM ($1.1bn vs. $130bn), and higher volatility (beta 2.61 vs. 1.65; 1‑yr max drawdown -31.34% vs. -27.23%). CHAT is a concentrated, generative‑AI‑themed portfolio (≈74% tech, ~20% communications) with top holdings including Nvidia, Alphabet and Oracle, while VGT is a broad, low‑cost 314‑stock tech tracker led by Nvidia, Apple and Microsoft. The practical takeaway for institutional investors is a clear trade‑off: CHAT offers higher short‑term upside potential but greater idiosyncratic risk, fee drag and limited track record, whereas VGT provides cheaper, deeper liquidity and sector diversification more suitable for long‑term, fee‑sensitive allocations.

Analysis

Roundhill's CHAT has materially outperformed Vanguard's VGT over the past year—1‑year returns of 52.11% for CHAT versus 23.06% for VGT as of Dec. 11, 2025—while charging a materially higher expense ratio (0.75% vs. 0.09%) and managing far less capital ($1.1bn AUM for CHAT versus $130.0bn for VGT). This performance differential comes with trade-offs that are visible in the risk profile and cost structure investors pay for active, thematic exposure.

CHAT exhibits higher volatility and drawdown: a 1‑year beta of 2.61 versus VGT's 1.65 and a max 1‑year drawdown of -31.34% versus VGT's -27.23%, yet its two‑year growth of $1,000 to $2,080 outpaces VGT's $1,648. Those metrics indicate larger upside when the generative‑AI theme works and correspondingly larger downside when it does not, so position sizing and liquidity considerations are more consequential for CHAT holders.

Holdings and tenure amplify the divergence: CHAT is a concentrated, generative‑AI‑themed fund (~74% tech, ~20% communication services) with top positions in Nvidia, Alphabet and Oracle and a 2023 launch date, whereas VGT is a 314‑stock, long‑standing passive tracker led by Nvidia, Apple and Microsoft. For investors, this implies CHAT can deliver higher short‑term alpha but entails greater idiosyncratic and fee risk, while VGT serves as a lower‑cost, more liquid core allocation for broad tech exposure.

Key Decisions for Investors

• Use VGT as the core, long‑term tech allocation given its 0.09% expense ratio, $130bn AUM and broad 314‑stock exposure,
• Deploy CHAT only as a tactical, limited sleeve for thematic generative‑AI exposure because of its higher 0.75% fee, greater beta (2.61) and smaller AUM,
• Size positions and set risk limits or rebalancing rules to account for larger drawdowns in CHAT (1‑yr max drawdown -31.34%),
• For large or fee‑sensitive portfolios prioritize VGT to avoid fee drag over time, and if allocating to CHAT monitor manager performance and AUM growth given its 2023 launch
