MDYG: Mid-Caps Stand To Benefit From Trump Policies
The SPDR S&P 400 Mid Cap Growth ETF provides low-cost exposure to mid-cap growth companies. While mid-caps generally trade at a valuation discount to large-caps, if we narrow the criteria to mid-cap growth, we see MDYG is similarly expensive. Although potential tax cuts from the Trump administration could benefit domestically focused mid-caps, uncertainty around policy implementation warrants caution.

MDYG: Not Better Than Its Large-Cap Growth Peer Fund
SPDR S&P 400 Mid Cap Growth ETF has performed well since 2022, but still underperformed its large-cap growth peer due to low exposure to technology stocks. MDYG's exposure to technology stocks is limited, which has been a drag on its performance compared to its large-cap peer.
