$TVIX$ $UVIX$ $DECP$ By Lawrence G. McMillan After the monster rally of 400 points in just a few days in early August, $SPX took a few days to consolidate. Now it is making new all-time highs once again. There should be some support in that consolidation area (7700-7800), with stronger support at the old highs (7620). There is also a gap at the 7600 level which would act as support as well. There has been a good deal of reluctance on the part of the investment community to climb on board this northbound train. But it finally looks like put buying is slowing down, and the rally is spreading out to more and more issues (i.e., breadth is improving).
TRADE PLAN for LOTTO Friday 🔥 $S&P 500(.SPX)$ printed a new all time high at 7817 today but failed to close above the 7800 resistance. It looks like SPX is winding up for a move to 8000.

$S&P 500(.SPX)$ just made new ATHs while $Invesco QQQ(QQQ)$ is still stuck. History says we crash 20% from here. But here’s why we don’t 👇 This EXACT divergence has happened 3 times before. Once it led to a multi-year bull run. Twice it preceded 20%+ crashes. How could the same setup have such different results? Here's how to tell which one you're dealing with: 🐻 2007 & 2018: One tired sector carried the index to its final high. Narrow leadership, no confirmation underneath.

By Lawrence G. McMillan A little more than a week ago, the FOMC meeting concluded (on July 29th), and traders were not happy. They sold the market before and after the meeting, closing $SPX that day at 7316. But then a series of events both real and psychological took place that released a buying panic. The net effect of this was that $SPX has broken out to new all- time highs, and has not fallen back below the old highs at 7620. That makes the $SPX chart bullish again, for the first time in a while. Targets are always nebulous things, but this could take $SPX to 8,000 or so. Equity-only put-call ratios have not rolled over to buy signals. As much as $SPX has risen, it has been accompanied by continued buying of puts on stocks. That is for protection most likely. So, even though these put-

"Stock God" Leopold was margin-called and forced to transfer his holdings — Citadel Securities swooped in and picked them up at a bargain price. The very next day, the market rebounded sharply with a massive surge. There's something worth reminding everyone about: Citadel Securities acquired Morgan Stanley's options market-making business in 2025 and is likely the largest options market maker in the market today. As we all know, options liquidity is provided by market makers, so Leopold's large block buy orders were essentially visible chips in the eyes of the market makers. This reminds me of the old saying — "the mantis stalks the cicada, unaware of the oriole behind." The large block trades I've been tracking might just be fat lambs waiting to be sheared in the eyes of the market makers
$TVIX$ $UVIX$ $DECP$ By Lawrence G. McMillan Despite one downward probe on July 29th, $SPX has managed to trade in a range and close at almost the same price every day. Near- term resistance is at 7430. After that failure on the 29th, the market bounced off the 7300 level with a vengeance the next day, so that is support. Even so, if one looks at the chart of $SPX in Figure 1, it is obvious that there is a new downtrend line that can be drawn, connecting the failed rally attempts that took place during July. There is support at 7300 and then 7240, with potential further support near the rising 200-day moving average in the 7100 area (that a

There's 2 levels to watch for $S&P 500(.SPX)$ the next 3 days. 1. Above 7500 = Bullish 2. Under 7400 = Bearish 3. Between 7400-7500= More chop. If you find yourself taking 50 trades a week with SPX stuck between 7400-7500, You need to size down and stop trading. Wait for the momentum first. There's a chance they raise rates tomorrow. If that happens, SPX to 7000 can come fast. We need to see Memory stocks and Chip stocks catch a bid and bottom out before going long again. Be patient and stay on your toes tomorrow. It's going to be a volatile one. Good luck everyone!! 🫡

SK Hynix Earnings Options Strategy: Long-Term Narrative Strengthens, But Near-Term Sentiment Has Col
I. Fundamentals: Long-Term Visibility Improves, Valuation Attractive SK Hynix is signing more amended long-term agreements with hyperscale data center customers, covering both DDR5 and NAND. Contract terms exceed five years, with approximately 60–70% of expected volume/pricing already locked in, significantly boosting future earnings visibility — this serves as micro-level confirmation of the large-capex-backed memory storage thesis. This earnings report is expected to deliver unprecedented operating profit exceeding 100 trillion won. Yet, with such strong expectations, the stock has still plunged dramatically, indicating that near-term market sentiment has completely broken down. II. Volatility Estimates and Scenarios Monday's pre-market reference price was 154.57, with implied movement o
SK Hynix Range-Bound Strategy: Annualized Yield Reaches 103%!
$SK hynix(SKHY)$ In the current range-bound market, U.S.-listed SK Hynix has a key weapon that the Hong Kong-listed 7709 $CSOP SK Hynix Daily (2x) Leveraged Product(07709)$ lacks: options! The Hong Kong ticker can only trade the underlying stock for price differences, while U.S.-listed SKHY allows you to Sell Puts during high volatility, turning range-bound movement directly into cash flow. Indeed, we've seen many large Sell Put orders over the past two days. Why is now particularly suitable for Selling Puts? SK Hynix reports earnings on 7/29, and pre-earnings IV has been pushed very high, making premiums especially rich. In addition, while the memory sector may not rally much in the short term, its long
Big Tech's Massive Capex Is the Floor Under Memory Stocks
I haven't written an article in a long time, and choosing to pick up the pen today feels rather meaningful—Big Tech's valuations got collectively marked down on this day, because the nature of their business has changed, from asset-light to asset-heavy. Some may remember the HALO (heavy assets, low obsolescence) concept that Goldman Sachs championed in the first half of the year. As it turns out, HALO just means "hard to die"—it doesn't mean "won't fall." When Big Tech collectively goes HALO, the broad market falls, and when the market falls, all stocks get dragged down with it. But on Thursday, semiconductor stocks—especially memory chips—held up remarkably well, because memory is the party being paid: it absorbs the cash flow coming from the HALO names. So when other stocks get marked do
100,000 Doomsday Calls on Software—Could Microsoft Spring a Surprise!?
The biggest difference between this week and last: negative sentiment toward memory chips is finally spreading widely. Last week was "buy the dip with full confidence"; but after CXMT's listing Monday, plus news of mass-produced Chinese DUV, fears of surging supply crushed an already fragile uptrend. For some names, a monthly pullback has turned into a quarterly one, and panic is fully setting in. Yet Tuesday's semiconductor crash didn't drag the broad market down—which, to me, isn't a good sign. Last week someone traded 70,000 contracts of the Aug 19 29 call$VIX 20260819 29.0 CALL$ . If the market won't correct even now, what is this VIX call betting on? Surely not a rate hike at Wednesday's FOMC?
$SPDR S&P 500 ETF Trust(SPY)$ A week of major pullback. SPY target remains the same as last week — looking at 710–720. Speaking of which, here's something interesting: software ETF saw a massive bullish (expiration-day) call order last Friday. This week's 88 call $IGV 20260731 88.0 CALL$ opened 100,000 contracts — that's $20 million spent on weekly options. And it actually rose on Monday. So can we chase IGV? Naturally, no. Currently, semiconductors and software are seesawing — the reason is that sentiment has temporarily shifted toward the software sector, which has richer cash flows. Notably, IGV's top holding is Microsoft. There is broad consensus that this week's earnings wil

Why Capital One’s Discover Integration Is Starting to Reveal Its Earnings Potential
$Capital One(COF)$’s second-quarter results offered an early indication of what the combined Capital One–Discover business may earn once acquisition-related distortions and integration expenses begin to settle. The company reported second-quarter net income of $3.0 billion, or $4.73 per diluted share. Excluding specified adjusting items, earnings were $5.81 per share. This compared with $2.2 billion, or $3.34 per share, in the first quarter. Capital One released the figures after trading closed on July 21. Capital One’s official earnings release and SEC-filed version provide the results. Purchase volume increased 26% year over year to approximately $249 billion, while average loans rose 29% to about $255 billion. These comparisons include the enlar
Why Charles Schwab Fell Despite Reporting Record Earnings
$Charles Schwab(SCHW)$’s second-quarter report contained record revenue, record earnings and strong asset gathering. Nevertheless, the shares fell approximately 2.5% on July 21. The reaction suggests investors were expecting more than a backward-looking earnings beat. Schwab generated record quarterly revenue of $7.1 billion, up 21% year over year. GAAP earnings reached $1.54 per share, while adjusted earnings were $1.62, this is 42% above the second quarter of 2025. June core net new assets increased 47% to $62.7 billion. Schwab’s July 21 earnings release provides the figures. These results reflect the strength of $Charles Schwab(SCHW)$’s business model. It earns asset-management and administration fees,
$Danaher(DHR)$’s July 21 selloff demonstrates an important market principle: when a company trades at a premium valuation, the composition and outlook of its earnings can matter more than whether it beats the current quarter’s consensus estimate. Danaher reported second-quarter revenue of $6.3 billion, up 5.5% year over year. Core revenue increased 3%, or 4.5% excluding respiratory-testing revenue. Adjusted earnings rose 8% to $1.94 per share, while operating cash flow reached $1.5 billion and adjusted free cash flow totalled $1.3 billion. Danaher’s official second-quarter release was published before the market opened on July 21. Those figures look healthy. Net earnings also rose 60% to $870 million, and both revenue and adjusted EPS exceeded expe
Intel Q2 Earnings Preview: Options Betting on a Run to $110
I. Fundamentals: Two Engines Determine Valuation The core focus of this earnings report is whether the two main threads — Server CPU and Foundry — can deliver a turning point. 1. Server CPU: The Core Engine for Earnings Growth Although declining PC sales pose a headwind, Intel is offsetting this with stronger CPU pricing power and AI demand. More critically, Agentic AI is expected to significantly boost server CPU demand, with the GPU/CPU ratio projected to drop from 2× to 1.1–1.4×. Leveraging the strong stickiness of x86 in the enterprise sector, Intel is well-positioned to become a key beneficiary of enterprise-grade Agentic AI. Server CPU revenue is projected to grow at a 28% compound annual growth rate (CAGR) through 2030. 2. Foundry Business: A Turning Point Has Emerged Front-end manu
Tesla Q2 Earnings Playbook: Some Are Betting Tesla Won't Break 400
I. Fundamentals: Strong Deliveries Come at the Cost of Profit and Cash Flow Tesla's overall Q2 deliveries beat expectations, and the full-year delivery guidance was raised. However, gross margins and EPS are expected to come under pressure and trend lower, while capex has breached $25 billion and free cash flow has turned negative. The market's real focus is no longer on car sales, but rather on the execution of Robotaxi rollouts and the production ramp of Optimus. Whether Tesla can build a moat in physical AI is the true make-or-break factor for this valuation. Key Data: Deliveries (raised): 2026 raised from 1.57M → 1.67M units; 2027 from 1.82M → 1.86M units. Capex: 2026 expected at $26.8B, with FCF loss of approximately $11.4B, in line with company guidance. Robotaxi: Launched in Miami o
