Must Read: Is Caution Needed in Semi-Related Stocks? A Deep Dive. 🔍
Semi-related supply chain stocks have been on fire this year, but a closer look at the big picture reveals a noticeable trend. When we zoom out to the multi-year and multi-decade levels, we see a potential concerning synchronisation:
$AOSL: Rejecting at 4-year resistance.
$VECO: Rejecting at 9-year resistance.
$AMSC: Rejecting at 18-year resistance.
$RMBS: Rejected at 22-year resistance.
Note: These are four random examples and actually four of the first five stocks I looked at.
Why This Matters
This convergence suggests that the current move isn't just about individual stock performance, it’s a sector-wide exhaustion point. When stocks with such varying histories all hit multi-decade diagonal ceilings simultaneously, it indicates that the easy money phase of the supply chain rally has reached a structural limit.
The market is likely shifting from "rising tide lifts all boats" to a phase of "selectivity." This serves as a warning that without a significant fundamental catalyst to break these historical slopes, many names are primed for a period of mean reversion or heavy consolidation as they digest these massive moves. This shift is particularly critical as we move into the heart of the Q1 earnings cycle, where guidance will either validate these levels or trigger a sharp reset (as we saw in $RMBS).
TA Lesson: The Gravity of Diagonal Trendlines 📝
You might wonder why a diagonal trendline drawn from two pivot highs years ago holds weight, especially if the stock has never traded at that level before. This is because trendlines are behavioural science and geometry.
When you connect two major pivot highs, you are mapping a slope based on past sentiment. Even if a stock hasn't hit that line in a decade, the line represents a proportional valuation ceiling relative to time. These upsloping trendlines act as dynamic resistance where algorithmic selling and institutional profit-taking cluster because the stock is perceived as moving "too far, too fast" relative to its historical growth trajectory. It’s not just a line on a chart, it’s the point where the market historically says "enough."
A Final Note
"Enough" unless the company can prove otherwise. It is important to remember that hitting a multi-year or multi-decade resistance line doesn't necessarily mean you need to sell your position immediately. In a strong bull market, overbought can stay overbought for a long time. However, it does mean the risk-to-reward ratio has changed. From a technical standpoint, the easy gains have been made, and any further upside from here likely requires much more effort (e.g. stronger earnings) to punch through these historical walls.
