SPDR SSGA My2028 Corporate Bond ETF (MYCH) Short Interest Jumps 33%

SPDR SSGA My2028 Corporate Bond ETF (MYCH) saw a 33.4% rise in short interest in December to 2,858 shares; low days-to-cover points to limited disruption.

Short interest in the SPDR SSGA My2028 Corporate Bond ETF (NASDAQ: MYCH) increased notably in late December, signaling a shift in trader positioning. As of December 31, short interest totaled 2,858 shares, up 33.4% from the December 15 total of 2,143 shares. The uptick drew attention because it represents a relatively large percentage change, even if the underlying share counts remain modest.

Based on an average daily trading volume of 9,538 shares, the days-to-cover ratio for MYCH is roughly 0.30 (2,858 ÷ 9,538). That low days-to-cover figure indicates it would take less than one trading day to buy back all shorted shares at the average daily volume—suggesting limited potential for a short squeeze and relatively low disruption from the increased short interest. Traders tracking short interest often use this metric to assess liquidity and potential market impact.

Why the increase matters for a bond ETF: short interest movements can reflect changing sentiment about interest-rate risk, credit quality in corporate bonds, or ETF-specific liquidity conditions. For MYCH—an ETF focused on corporate bonds maturing in 2028—investors watching short interest may be reacting to shifting expectations about credit spreads or the macroeconomic outlook affecting corporate borrowers.

Context is key. Although a 33.4% rise sounds significant, the absolute short interest on MYCH remains small compared with many equity ETFs. The ETF’s listing on NASDAQ and its function as a fixed-income vehicle mean that price action is typically driven more by interest-rate moves and credit developments than by short-term speculative flows.

What investors should watch next: monitor ongoing short interest reports for further trajectory, keep an eye on average daily trading volume, and watch macro headlines that influence corporate bond spreads (Fed policy, economic data, and credit events). For traders and long-term investors in bond ETFs, combining short interest data with portfolio-level analysis will provide a clearer picture of risk and liquidity in MYCH.
