S&P 500 Outpaces Small Caps Again as Treasury Liquidity Squeeze Keeps Risk Appetite in Check

There’s a reason nobody at the bar is bragging about their small cap positions right now. The S&P 500 continues to grind higher, leaving the Russell 2000 looking like a forgotten stepchild. Bigger is still better, and January’s price action made that painfully clear. Seeking Alpha’s latest hit piece on small caps isn’t wrong: the odds are more stacked against them than ever. Meanwhile, Wall Street can’t stop talking about the liquidity drain from Treasury issuance, and risk assets are feeling the pinch.

Let’s talk facts. The S&P 500 is the only party in town with a velvet rope. Small caps, once the darlings of the reopening trade, are now the wallflowers. The latest batch of data shows large cap outperformance hitting new cycle highs. Treasury settlements and a rising TGA have drained $64.3 billion from market liquidity, according to Seeking Alpha. That’s not a rounding error, that’s a firehose. The result? Risk assets are struggling to find buyers, and the “everything rally” narrative is looking increasingly threadbare.

The macro backdrop is no friend to the little guy. Corporate earnings are solid, but the market doesn’t care. Geopolitical shocks are the new bogeyman, and even the best balance sheet can’t hedge World War Three. Liquidity is the real story, and it’s not coming back anytime soon. The Fed is still in “higher for longer” mode, and every uptick in Treasury supply is another headwind for risk. Investors are crowding into the S&P 500 because it’s liquid, it’s safe, and it’s not going to zero. Small caps? Good luck finding a bid.

Historically, small caps outperform when growth is accelerating and liquidity is abundant. Today, you have neither. The Russell 2000 has failed to add alpha for years, and the technicals are ugly. The S&P 500, on the other hand, is flirting with new highs. The divergence is stark, and it’s not just a US phenomenon. Global risk assets are under pressure, and the only thing working is size and safety. The “stock whisper” crowd is watching from the sidelines, hoping for a reversal that never comes.

The analysis is simple. This is a market that rewards scale, balance sheet strength, and liquidity. Small caps are the first to get hit when the punch bowl is taken away, and that’s exactly what’s happening. Treasury issuance is the silent killer, draining liquidity and forcing investors up the quality curve. The S&P 500 is the last man standing, and until the liquidity picture improves, that’s unlikely to change. The energy sector is flashing early warning signs, but for now, the rotation is out of small caps and into the megacaps.

Strykr Watch

Technically, the S&P 500 is testing resistance at the $4,900 level. A clean break targets $5,000, with support at $4,850. Small caps are stuck in a range, with the Russell 2000 unable to reclaim its 200-day moving average. RSI on the S&P 500 is elevated but not extreme, suggesting there’s still room to run. The liquidity squeeze is real—watch for any signs of relief from Treasury supply or a dovish Fed pivot. Until then, the path of least resistance is higher for the big boys, and sideways (at best) for the rest.

The risks are obvious. If Treasury issuance accelerates, the liquidity drain could get worse. A geopolitical shock could hit risk assets across the board, and small caps would be the first casualties. A hawkish Fed is always lurking, and any sign of earnings disappointment could trigger a selloff. The energy sector is a leading indicator—if it rolls over, the rest of the market could follow.

But there are opportunities. For the nimble, buying dips in the S&P 500 with tight stops makes sense. If small caps finally catch a bid, the rotation could be violent. But for now, the smart money is staying big, liquid, and boring. Dividend stocks are also in play, offering stable income against a volatile backdrop.

Strykr Take

Don’t overthink it. This is a market that rewards size and punishes risk. Until the liquidity picture changes, stick with what’s working. The S&P 500 is the only game in town, and small caps are just noise.
