TSMC blows past earnings and extends AI timeline — long chipmakers riding the wave

Verdict: Great Thesis, Wrong Price — Wait for the RSI Reset

The strongest case for this idea is fundamental: TSM's last filed year shows revenue up 33.9% to NT$2.89T with a 40.0% net margin, and AMD's June 2026 quarter showed revenue up 12.5% to $11.5B with net margin expanding from 13.5% to 19.9% — the AI build-out is visible in the numbers, not just the headlines. The strongest case against is that both legs are already extended and insiders are selling: AMD's RSI (14) sits at 72.7 versus the strategy's required sub-50 entry zone, TSM's nearest resistance at $436.04 is essentially at the last close, and ownership filings for the quarter ended June 30, 2026 show roughly $153.2M of net open-market insider selling at AMD across 17 holders. The completed backtest returned 12.7% with a 4.1% maximum drawdown, but it rests on exactly one trade over 60 months, so that perfect record is a single outcome, not a distribution. No robust nearby-parameter setup was established because the sensitivity evaluation ran out of time, so the published rules are the only configuration tested. The verdict flips only if a pullback actually arrives: RSI falling back below 50 and then crossing up through 45 while price holds above the 20-day EMA, with AMD's operating cash flow (down 39.3% sequentially to about $1.6B) stabilizing at the next print.

Trade now: momentum has outrun the entry — patience is the position

Nothing is tradable today under this strategy's rules, and that is the correct read, not a caveat. Both AMD (last close $520.22) and TSM ($435.56) are already above their 20-day EMA levels ($481.47 and $421.89 respectively), and trend strength (ADX) is comfortably above the 18 threshold for both. The blocking condition is RSI: the entry needs a fresh RSI (14) cross above 45 while still below 50. AMD's RSI is 72.7 — 22.7 points above the 50 ceiling — and TSM's is 65.5, 15.5 points above it. In plain terms, both stocks are extended, and the strategy is designed to buy a pullback-and-resume, not chase strength. What waiting means concretely: RSI on each ticker must fall back below 50 and then cross up through 45 while price holds above the 20-day EMA. For AMD, price is $38.75 above its EMA, so even moderate consolidation could restore the price condition quickly — the RSI reset is the binding constraint. On any valid entry, the risk math is fixed: a 2.4% stop against a 4.8% profit target, roughly 2:1 reward-to-risk, with a forced exit after 40 trading bars. The completed backtest supports the discipline: one traded signal over a 60-month window returned 12.7% with a maximum drawdown of 4.1%, and the same return held in the 12- and 24-month windows with drawdowns as low as 2.9%. Exits were filled on daily bars rather than intrabar data, so treat those figures as coarse. One process note: the parameter-sensitivity evaluation ran out of time, so no robust nearby-parameter setup was established — follow the published rules exactly as written. Set alerts, not limit orders: AMD RSI crossing below 50 and TSM RSI crossing below 50 are your early-warning signals that an entry window may be forming.

Why the bull case still has support

The fundamental engine behind this long thesis is running hot on both legs. TSMC's most recent filed year (ended December 31, 2024) shows revenue of $2.89 trillion in NT dollars ($2,894B), up 33.9% year over year, with net income up 36.0% and a 40.0% net margin — and per CNBC, the second quarter of 2026 delivered profit growth of more than 77% that beat estimates. AMD's momentum is just as sharp: in the quarter ended June 27, 2026, revenue rose 12.5% sequentially to $11.54B, net income jumped 66.1% to $2.30B, net margin expanded from 13.5% to 19.9%, and gross margin improved to 53.8%. The idea's claim that demand for AI hardware is accelerating, not peaking, is visible in the actual numbers, not just the headlines. Peer context strengthens the quality argument. TSM ranks at the 98.4th percentile of 854 information-technology peers on operating margin and the 99.9th percentile on free cash flow ($870B NT), while AMD sits at the 87th percentile on operating margin and the 98.7th percentile on free cash flow despite spending 22.7% of revenue on R&D. These are not speculative AI names — they are the two most profitable operators in the sector, which is the right place to be if the AI build-out lasts, as TSMC publicly asserts it will for at least three more years (per the Bloomberg piece of July 16, 2026). The catalyst tape is dense and directional: TSMC raised spending and long-term margin guidance (per the July 16 Yahoo Finance coverage), Jensen Huang publicly dismissed Vera Rubin delay rumors and affirmed 'giant' production volumes, Meta committed $50 billion to AI data centers, and TSMC signed a major US manufacturing deal. Bank of America expects AMD to beat and raise on surging AI server demand. That is exactly the headline cluster the strategy's news-adjacent entry conditions were designed to trade. On the strategy evidence itself, the completed backtest is constructive: across a 60-month daily evaluation the setup returned 12.7% on a single completed…
