The market backdrop
Starting the back half of the year, the broad picture rests on the data above everything else, read through quantitative and technical analysis. The major indices, whether the S&P 500 or the Nasdaq 100, have been consolidating after strong moves off the March lows, which is normal behavior. What matters more is the health beneath the surface, measured by market breadth. The advanced-decline line for the New York Stock Exchange trades near all-time highs, and international markets show the same broad-based equity strength. This is not a US phenomenon alone, and it continues what has been in place since the end of the first quarter.
That breadth argument also cuts against a popular worry. Plenty of people describe the market as dangerously concentrated. The S&P 500 may look concentrated by weighting, yet participation is broad. Jumping to a "it's a bubble, market cap is too concentrated" conclusion is the wrong read, because the data doesn't support it.
Pick one: the S&P 600 small caps
Small caps are interesting for a few concrete reasons. First, the S&P 600 trades at all-time highs, and indices and stocks making new highs tend to keep making new highs. Second, small caps are probably underowned, which is a rational result of their underperformance since roughly 2018. A chart of the S&P 600 relative to the S&P 500 from 2018 onward shows a steady downtrend until recently. So the group being underowned makes sense given that history.
The turn is what changes the calculus. The S&P 600 is making new highs while also turning higher on a relative basis. Measured against the S&P 500 with a 10-week moving average, the ratio is starting to break above that moving average, which points to the early stage of a rotation into small caps. It looks early, and it's happening in a group that is likely underowned.
On the chart, the prevailing shape is a rising wedge. The short-term blue trend line that peaked near 1816 has been breached, and price now sits back inside the wedge. The horizontal levels worth watching come from old highs becoming new support after the breakout: 1816.83, an old high with a subsequent low near 1765, and a similar old high with a subsequent low near 1710 if price starts traveling down again. Old resistance turning into new support after a breakout is a common event in technical analysis. The 5-day EMA in dark blue sits at 1787.72, and price is a bit above it, so a stronger close above that moving average and above the wedge would matter on the upside. To the downside, the 21-day EMA in teal at 1751 lines up closely with the lower boundary of the wedge, giving a confluence point that reads as support for a bull or a breakdown trigger for a bear. RSI eased after a couple of very brief pushes above the 70 overbought threshold and now sits near 64. A long, moderately sloping green trend line remains in play, which keeps the setup on the more bullish side. On the day, the S&P 600 traded at 1789.37, up about four tenths of a percent, with the Russell and the S&P also higher.
Pick two: the MAGS ETF, or the "Lag Seven"
The label fits. The Mag 7 is down on the year, and that weakness actually speaks to the strength of everything else. The S&P 500 is up nearly 10% while the Mag 7 stocks are down between 1 and 2%. Those seven names are drawn from three sectors, technology, consumer discretionary, and communication services, and those groups together make up over 50% of the S&P 500. So the index staying strong without help from the Mag 7 tells you the broad-based health is real and sits under the surface.
The reason the Mag 7 still deserves attention is the AI trade. That term is broad and covers a lot, and at some point everything becomes an AI trade. For now the Mag 7 are essentially the hyperscalers, the companies spending to build out AI infrastructure, and they are lagging. At the same time, the semiconductor stocks, the key input into that buildout, trade at or near record levels. This is where a 120-year-old idea from Dow Theory becomes useful: confirmation. The hyperscalers who buy the inputs are weakening while the semiconductors that supply the inputs stay strong. That is a non-confirmation, a divergence. The key question for investors is how long it can last. Nobody knows for certain, but it can't last forever. Eventually further weakness in the Mag 7 will weigh on the broader market. The catalyst to watch is the semiconductors: if they start to roll over while the Mag 7 stays weak, owning the large-cap indices gets increasingly difficult. That is precisely why some people are already positioning for it by rotating into small caps.
On the technicals, MAGS made a run at its highs near 71.16 and, crucially, did not reach them even though it came close, forming a double-top shape without actually testing the resistance. From there came a sharp collapse. The blue trend line has broken, and a much steeper white upward-sloping trend line has also broken, leaving the near-term trend in no man's land. Breaking above the past couple of sessions' highs points toward a relative high around 67. To the downside, a gap near 64.50 stands out, and 60.70 marked the low of the recent decline. The moving averages tell a different story than the S&P 600's: three common ones, the 5-day, 21-day, and 63-day EMAs, representing one week, one month, and one quarter in dark blue, teal, and gold, cluster near 65, a notable confluence. The yearly 250-day EMA in orange comes in at 62.36. RSI mirrors price, having broken both its green shorter-term trend line and its red longer-term downward trend line, sitting near 51.70, just above the midline that separates bearish from bullish momentum. On the volume profile, price is within the largest node of the past year, roughly 64 to 67, and has paused at the point of control, the heaviest-traded area, a thick red line near 65.16. Above that node sits a smaller pocket of activity between about 68.50 and 69.50. On the day, MAGS moved higher, with only Microsoft in the red among the seven.
Pick three: Micron, the semiconductor bellwether
Individual names aren't the focus for portfolio construction, but bellwethers deserve attention because they read the bigger themes. Micron has become the bellwether of the semiconductor space, arguably taking the baton from Nvidia for now. Tie that back to the divergence: the MAGS names sit at a key inflection point on both the moving averages and the volume data, so the question becomes whether the semiconductors catch down to the Mag 7 and start rolling over. Micron is the data point to watch, a well-owned name on everybody's radar and, for now, the heartbeat of the group. The trend is still solidly positive. You could argue Micron has become extended, since it ran well above both its 200-day and 50-day moving averages, but being extended historically is a poor sell signal on its own. The move worth watching is a further breakdown in Micron while the Mag 7 stays weak, which would bring more caution into the market view. That isn't playing out yet, and the strength under the surface, including the NYSE advance-decline at all-time highs, argues against it for now.
Micron had a brutal week, giving back nearly all its gains after a strong earnings report, then moved higher on the session. There was even outside commentary framing the bounce as a possible return to optimism, with Samsung's preliminary results due the next day as a potential preview. This is a name up more than 700% over the trailing 52 weeks, so the swings run in both directions.
On the chart, all the trend lines point up, which keeps the "trend is your friend" case alive, though only possibly. Price touched the white trend line built off the lows, which is roughly where it bottomed on Thursday, after a roughly 20% haircut from the highs near 125.5. Vicious pullbacks are the price of admission on high-flying, volatile names even when the larger trend holds. The horizontal levels of interest, mostly high closing levels, sit near 121.35, a notable gap with a subsequent high near 116.5, subsequent lows near 101.2, and further down 86.2, a double-bottom level that stands out if things deteriorate. The moving averages cluster again: the 5-day and 21-day come together roughly between 103 and 104.2, and the longer 63-day EMA sits near 83.1, approaching the 84.2 level and likely to catch up in the coming days as a possible support zone on a significant decline. RSI has fallen below its green trend line and holds a hair above the 50 midline, around 50.20, so a push below that trend line paired with a matching RSI decline would offer confirmatory downside evidence. On a three-month volume profile, chosen to capture the rapid climb, price sits at the very edge of a large node of trading between about 101 and 110, with another sizable pocket lower between 89.5 and 97.5. Extreme trading runs through this name, and those are the levels that matter from a volume standpoint. On the day, Micron traded around 105 and change, up about 3% and trying to regain lost ground.
The through-line
The three picks are one connected thesis. Breadth is healthy and broadening, and small caps are turning up from an underowned base, which is the constructive side. The Mag 7 is lagging and its trend structure has broken, while semiconductors have held at record levels, and that split can't persist indefinitely. Micron is the tell. As long as it and the rest of the semiconductors hold, the divergence stays benign and the rotation into small caps looks like an early opportunity. A genuine breakdown in Micron while the Mag 7 remains weak would be the signal that the divergence is resolving to the downside and that more caution is warranted.
