Bought the dip at 200 for $NVDA, which I never dreamed of doing yesterday
The next day it fucking dropped nearly 10%
Is there still any humanity?
This round of decline looks more like a valuation reset market; the characteristics of a demand collapse market have not yet appeared, and the two types of markets behave very differently. $SOXX $NVDA
The feature of a valuation reset is that stock prices fall while earnings expectations remain unchanged, causing valuation multiples to be compressed. The Philadelphia Semiconductor Index has pulled back about 22% from its high, but analysts have not significantly lowered earnings expectations for next year; what falls is how many multiples investors are willing to pay, not how much profit can be made.
The characteristics of a demand collapse are completely different. You first see cloud providers cut capital expenditures, customers delay or cancel orders, DRAM and HBM prices reverse downward, and then earnings expectations are cut round after round, with stock prices falling alongside earnings, measured in quarters.
The responses to these two markets are also opposite. Valuation resets usually come fast and go fast; once panic is digested, good companies get re-priced at lower multiples, making the pullback an opportunity. Demand collapses should be avoided; the earlier you bottom-fish, the more you lose.
The evidence we see now leans toward the former. Policy panic, financing anxiety, and interest rate concerns all suppress multiples; hard data on the demand side, such as data center revenue and storage price increases, are still moving in a positive direction.
However, the last drop I mentioned did not materialize, reminding me not to treat bias as certainty. Whether the reset will evolve into a collapse depends on three boundaries: cloud providers cutting capital expenditures, weakening DRAM and HBM, and the 10-year US Treasury yield rising above 5%.
First, distinguish which type of market it is, then decide whether to avoid or wait.
The market is very likely to follow one of two paths: if cloud vendors' capital expenditures hold steady, it will be closer to the kind of recovery seen in 2018 or from 2024 to 2025; if capital expenditures are cut, it will lead to a longer cycle reset. $SOXX $NVDA $AMZN $MSFT $GOOGL
Near-term high-elasticity chips may continue to lag the broader market. This was demonstrated once on 11/4: the Philadelphia Semiconductor Index fell 3.13% to close at 10268.65, a roughly 22% pullback from around 13218 on 10/6, while the S&P 500 rose 1.6%. Such divergence—weak chips and strong market—historically results either in chip catch-up or market pullback; the key is which side’s fundamentals fail first.
Seasonality after the midterm elections can only be considered a weak reference. Some say that in some midterm-year studies, the S&P 500 tends to be positive from October to December, but policy approvals, licensing pace, and interest rates are the hard variables; seasonality alone cannot support positions. $NVDA’s guidance on 11/17 can be one of the path confirmation points, but before confirmation, we still need to see if cloud vendors publicly cut budgets.
The failure conditions are fixed: cloud vendors cut capital expenditures, DRAM and HBM weaken, or the 10-year US Treasury yield rises above 5%. Before these boundaries are broken, no leverage, no short chasing; holding cash and waiting is a reasonable option. Being bullish does not mean holding on stubbornly; if the trend is not repaired, do not hold heavy positions; once boundaries are broken, reassess according to the worse path.
The path switches based on conditions, not guessing single-day directions.
This kind of opportunity really only comes once in ten years
For those with light or even no positions
Right now, I've truly never seen such a good opportunity
But what should I do?
For those of us with large positions
Are we just going to become fuel?
It dropped like this with no warning at all
$QQQ $SPY $SOXX
The AI bear market theory has come around several times this year—once in March, once in July, and now again. Each time, the key point is whether demand has truly collapsed. $NVDA $SOXX
In March, the market worried that efficiency improvements would reduce computing power demand. In July, the semiconductor sector fell to around 10447, citing overvaluation and peak capital expenditure. This time, the reasons are post-election policy panic combined with financing anxiety. The reasons differ each time, the voices grow louder, but the conclusion is always the same: AI has peaked.
Everyone has seen the results of the first two rounds—capital expenditure continued to rise, and the semiconductor sector later climbed to around 13218. This doesn’t prove this time will be the same. My previous prediction of a final drop didn’t hold this time, as it broke below 10447, and that must be acknowledged.
But the repeated appearance of the bear market theory itself indicates one thing: the valuation of the AI chain is extremely sensitive to sentiment, requiring a stress test every few months. Volatility will be the norm, and this must be accepted; portfolio positions should be adjusted accordingly.
How to distinguish whether this time is just noise or a real signal? Look at the boundaries. Have cloud providers cut capital expenditure? Have DRAM and HBM prices weakened? Has the 10-year US Treasury yield returned above 5%? If none of these three break, the bear market theory remains at the sentiment level.
I won’t ignore this time just because the previous two bear market theories were wrong, nor will I turn bearish just because the voices are loud.
The bear market theory is always present; the boundaries are always the answer.
After semiconductors dropped more than 20%, historically recovery is very common, and continuing to dig lower is also common, so in the short term, neither shorting nor going long is advisable. $SOXX $NVDA $MU $AMD
Some say: Since 2005, $SOXX has experienced 6 drops exceeding 20%; among them, 4 times it rose in the following 12 months, with a median gain of about +28%; but within one year after buying, the median also saw a further pullback of about 20%. In other words, even if the bottoming direction is right, the process can still shake people out, and there may still be another round of pullback within a year.
Some say: Since 1995, $SOX bear markets with drops over 20% have had a median depth of about −38%, with peak to trough lasting about 9 months; typical cycles mostly fall between −30% and −50%, only systemic crashes like in 2000 and 2008 were deeper. Now from around 13218 near 10/6 to 10268.65 on 11/4, about −22%, while the S&P 500 rose 1.6% the same day, the depth is still in the first half of a normal cycle.
Putting these two points together clarifies the window. Statistically, most will come back, but most will also suffer first. A single-day rebound does not solve this issue; the boundaries set by cloud vendor capital expenditures, DRAM and HBM prices, and the 10-year US Treasury yield determine which historical path it will follow.
Before these boundaries are broken, do not use leverage, do not chase shorts, and do not rush into heavy positions. Being bullish does not mean holding on stubbornly. Look for improvement in orders and prices, not single-day rebounds.
This market situation most resembles the policy shock correction of 2018: chip stocks plunged, the broader market still held up, and demand did not collapse accordingly. $SOXX $NVDA $AMD
The Philadelphia Semiconductor Index closed at 10268.65 on 11/4, down 3.13% for the day, retreating about 22% from around 13218 near 10/6. From the high of about 14635 on 6/22, it fell to around 10447 on 7/29, a drop of approximately −28.6%, and on 11/4 it broke below 10447 again. On the same day, the S&P 500 rose 1.6%. Weak chips and a strong broader market is a typical sector panic, not an index crisis.
Some say that during the 2018 trade war, the SOX fell about 26% over roughly nine months, and after policy pressure eased and demand remained, it recovered to previous highs in about four months. A more recent template is the AI panic combined with external shocks from 2024 to 2025, with a total retracement of about 40%. Some say that after the April low, it returned near the peak in about five months, assuming earnings reports and capital expenditures did not collapse.
The 80% drop from 2000 to 2002 is less applicable now. That cycle was characterized by buyers disappearing and capital expenditures stopping; currently, cloud providers $AMZN $MSFT $GOOGL are still spending, though approvals and policies have pushed timelines back.
Treating this round as a policy compression similar to 2018 or 2024–2025 fits the market better than viewing it as an internet bubble burst. The invalidation conditions remain the same three: cloud providers cut capital expenditures, DRAM and HBM weaken, and the 10-year US Treasury yield returns above 5%.
History provides a reference frame; confirmation depends on orders.
