Separately managed accounts (SMAs) are gaining traction among investors, offering personalized portfolios with features like tax optimization and tailored investment preferences. Once reserved for the wealthy, advancements in technology have made SMAs more accessible, with minimum investments as low as $5,000 through platforms like Fidelity. 

While SMAs allow for benefits such as tax-loss harvesting and charitable stock donations, they often come with higher fees compared to ETFs, which can make them less cost-effective for many retail investors. 

Critics argue that customization can lead to active management pitfalls, with most SMAs historically underperforming benchmarks after accounting for fees.
