Lopsided Stock Market Momentum Suggests This is the Top… or the Buying Opportunity of the Century

It seems too early to read this yet, with a major Fed catalyst due out this afternoon, but as of Tuesday, Sept. 15, roughly over half of the Russell 3000 Index – some 1,613 components! – have a “sell” signal from Barchart’s TrendSeeker® indicator.

The broad-based Russell 3000 seeks to measure roughly 3,000 of the largest publicly traded U.S. companies, and it represents about $80 trillion in market cap as of the June 2026 annual rebalancing. That’s 98% of the publicly traded market, give or take.

Without analyzing all 1,600 signals individually, a TrendSeeker “sell” suggests, on the surface, that a significant portion of the market is experiencing bearish momentum.

Yet at the same time, both the S&P 500 Index ($SPX) and the Nasdaq-100 Index ($IUXX) are 5% or less from their respective all-time highs (ATHs)...

S&P 500 and Nasdaq-100 near ATHs.

…despite less than 10% of the S&P 500 sporting a 100% Barchart technical “buy” Opinion.

Until macro pressures ease and the Fed provides greater clarity on the path of monetary policy, the narrow market breadth leaves investors walking a tightrope between capitulation and opportunity.

The question is whether this lopsided market ultimately represents an exhausted rally that gives way to a meaningful correction or whether it is the early stage of a much broader opportunity, provided participation begins to expand beyond the relatively small group of stocks currently carrying the major indexes.

Simply put, this is either the top, as in capital-T Top, or one of the greatest buying opportunities of the century.
