Chart of the Day - Wednesday, January 7, 2026

🏆 Today's Chart of the Day was shared by JC Parets (@JC_ParetsX).
 

• The S&P Mid-Cap 400 ($MDY) pushed to new all-time highs for the first time since 2024, after a prolonged period of underperformance versus both Large and Small-Caps.
   
• JC notes that compared to the S&P 500, $MDY is far less concentrated in Technology and carries heavier exposure to cyclical sectors like Industrials, Financials, and Consumer Discretionary. 
   
• Notably, Mid-Caps are carrying their highest short interest in a decade, which may provide additional upside momentum if these positions begin to unwind. 
   

The Takeaway: With Mid-Caps resuming higher from their secular uptrend, the broader market backdrop remains healthy and intact.
