SPTS has delivered a 1-year return of 2.47%, which substantially outperforms the category median of 0.33%.

The price currently sits at $28.85, near the bottom of its 52-week range, reflecting its position at 8.3% of the high-low spread. The ETF’s grade has remained unchanged at C over the last 35 tracked days, indicating stable assessment metrics. Historical price data is available for only 3.0 years, limiting the depth of long-term trend analysis.

The fund exhibits Very Low volatility at 1.25% annualized, suggesting a stable price trajectory relative to broader market movements. Its beta of 0.23 indicates that SPTS moves only about 23% as much as the overall market, providing a dampening effect on market swings. Despite this low volatility, the Sharpe ratio of -2.02 reflects a negative risk-adjusted return profile over the measured period. The maximum drawdown was limited to -0.96%, highlighting the fund's resilience against significant losses. Liquidity is supported by an average daily volume of 1,967,536 shares, though the bid-ask spread of 0.90% suggests moderate trading costs.

SPTS Liquidity, Domicile & Tax Treatment

Liquidity: Quoted bid/ask spread is 0.90% and average daily volume is 2.0M/day. Tighter spreads and higher volume mean lower round-trip trading costs; this is a live-market snapshot and can widen during volatile sessions. AUM of $7.29B provides ample scale, supporting tight spreads and issuer commitment to keep the fund open.

Domicile & tax treatment: SPTS is a US-domiciled, SEC-registered ('40 Act) exchange-traded fund. Dividends and capital gains distributions are reported to US investors on Form 1099-DIV, and the fund is not subject to the PFIC reporting or UCITS-specific rules that apply to Irish- or Luxembourg-domiciled funds. Non-US investors should note that US-domiciled ETFs are generally subject to 30% US withholding tax on dividends (unless reduced by treaty) and to US estate tax exposure on the position — Irish-domiciled UCITS ETFs tracking the same index often avoid both, which is why non-US residents frequently prefer the UCITS equivalent where one exists.
