TSMC crushes earnings but chip stocks sink anyway — buy the AI dip

Verdict: a strong thesis still waiting for its first tradeable dip

The thesis is genuinely compelling on fundamentals: TSM grew revenue 33.9% to $2.89T TWD in fiscal 2024 with free cash flow up 197.9%, ASML lifted 2026 guidance twice per Yahoo Finance, and TSM's June 30, 2026 ownership filings show net insider open-market buying of roughly $370K across 20 holders. But the entry rules — a close below the lower Bollinger band with RSI at or below 40 crossing back up — never fired once across 60, 24, and 12-month windows totaling 1,236 daily bars, and no robust alternative parameter setup was established after the sensitivity evaluation exceeded its time budget. Right now TSM's RSI sits at 65.5, needing about 25.5 points to reach the 40 trigger, while ASML's RSI of 50.2 is nearer at about 10 points away. The strongest point against is that a 2.3% fixed stop is easily overwhelmed in a sector where headlines move these names 5-10%, and the near-zero pair correlation of -0.09 offers little protection if both fall together. The verdict: treat this as a high-quality watch-list setup and wait for the next earnings-driven dip to bring the entry conditions to life.

Trade now: the dip-buy conditions are close, but not live

The idea argues TSMC's post-earnings selloff is a disconnect that resolves higher, per the thesis. Today the setup is a watch-list, not a signal. TSM closed at $435.6, about 1.7% above its lower Bollinger band at $421.8 and above its 9-day EMA at $425.8, so the band and moving-average parts of the entry are nearly in place. The blocker is momentum: the 14-day RSI sits at 65.5, far above the 40 threshold the entry requires — roughly 25.5 RSI points of distance. ASML closed at $1,729.5, already below its lower band at $1,757.1 and above its EMA at $1,724, but its RSI of 50.2 also needs to reach 40 and turn back up. Concrete risk terms if an entry triggers: the strategy carries a fixed stop at a 2.3% loss on the position and a take profit at a 4.6% gain — an effective reward-to-risk of about 2:1 — plus a time exit after 90 bars and signal exits if RSI pushes above 70 or trend strength exceeds 40. At current prices, a 2.3% stop on TSM is roughly $10 below the last close and a 4.6% target roughly $20 above it. "Wait" means exactly this: do nothing until a TSM or ASML daily close puts price below the lower Bollinger band while RSI is at or below 40 and then crosses back above it. RSI above 70 on either name before an entry would argue the rebound already happened without you. No robust parameter setup was established for this strategy, so treat the published thresholds as the plan of record rather than a tuned configuration.

Genuine cash-flow machines meet a sentiment-driven selloff

The news flow strongly supports the idea's disconnect thesis. Per Yahoo Finance on July 15, 2026, ASML beat Q2 earnings and raised its 2026 guidance for the second time — a remarkable vote of confidence in equipment demand. The next day, Yahoo Finance reported TSMC raising both capex and revenue forecasts on growing AI chip demand, while Reuters flagged record second-quarter profit expectations ahead of the print. Two of the most important companies in the semiconductor value chain raised outlooks within 24 hours of each other, and yet, per Investor's Business Daily's July 16, 2026 coverage, TSMC shares fell as tech futures slid. That is precisely the sentiment-versus-fundamentals gap the idea is trying to harvest. The fundamentals give the dip-buy real substance. ASML's fiscal 2025 numbers (period ended December 31, 2025) show revenue up 15.6% to $32.7B, net income up 26.9% to $9.6B, net margin improving nearly 3 percentage points to 29.4%, and free cash flow up 21.8% to $11.1B. Debt-to-equity fell 30.6% year over year to 0.14. TSMC's fiscal 2024 results are on another level: revenue up 33.9% to $2.89 trillion TWD, net income up 36.0%, gross margin at 56.1%, and free cash flow of $870.2B TWD, up 197.9% from the prior year. Both companies rank at the 99.9th percentile of their sectors for free cash flow, and TSMC's 45.7% operating margin sits in the 98th percentile among 854 IT-sector peers. Crucially for a rebound thesis, the insider tape leans supportive on the TSMC side: the June 30, 2026 filings record net open-market insider buying of roughly $369,926 across 20 holders. Insiders buying into a selloff — even in modest size — is the kind of confirmation a contrarian entry wants, and it was filed after the selling pressure described in the news began. The shareholder-return track record also reduces left-tail risk while you wait for mean reversion. TSMC's dividend has grown about 31.9% annually over five years (trailing twelve months of $3.57 per share), and ASML's about 26.8% annually (trailing twelve months of $9.06). These are companies returning cash from record profitability,…
