The broader market is selling off because surging government bond yields raise fears of more Fed rate hikes, which makes borrowing expensive and future profits worth less. Against that ugly backdrop, Microsoft is rallying to its highest close of the year

Verdict: strong businesses, wrong moment — wait for the pullback

The thesis is fundamentally well supported: Microsoft's fiscal Q4 (ended June 30, 2026) delivered $90.0B of revenue up 17.7% year over year with $19.6B of free cash flow, and Costco beat profit expectations per the September 24, 2026 MarketWatch report — though the beat was helped by one-time tariff refunds, and Costco's 12.8% gross margin sits in only the 20th percentile of Consumer Staples peers, leaving little cushion for cost shocks. The strongest point against the trade is the ownership tape: as of the June 30, 2026 reporting window, insider filings show roughly $47.7M of net open-market selling at Microsoft and about $847K at Costco — distribution into strength, not accumulation. The timing side is also unresolved: the pullback entry rules never fired across 1,236 daily bars over five years, and today's RSI readings of 71.1 on MSFT and 61.8 on COST sit 31 and 22 points above the required at-or-below-40 level, so this remains a watch-list setup waiting for the momentum cooldown the idea itself anticipates. Note that no robust parameter setup was established — the sensitivity evaluation ran out of budget without a recommendation — so the timing rules on offer are the thesis-consistent ones, not optimized ones. A bond-yield-driven risk-off move that pulls RSI to 40 or below while both names hold their trend structure would flip the verdict toward entry; continued insider selling alongside a fresh Microsoft guide-down or a deeper Costco margin squeeze would kill it.

Trade now: three pullback entries, none armed — the RSI gate is the one that matters

This is a watch-list setup, not an active signal. The strategy looks for a pullback-to-support reversal long on each of MSFT, COST, and SPY on daily bars, and right now the entry conditions are not met on any of the three — the rules were evaluated on real daily bars and simply did not fire, which is a statement about market conditions, not about the setup. The blocking condition is identical everywhere: the daily RSI (14) needs to be at or below 40, and it is nowhere close. MSFT's RSI reads 71.1 with the stock at $518.39 — deep momentum territory, 31 points above the entry threshold. COST sits at $921.23 with an RSI of 61.8, about 22 points away. SPY is the closest at $771.35 with an RSI of 59.8, still roughly 20 points from triggering. The other conditions are partly in place: SPY and MSFT both trade above their 50-day EMA, and the Bollinger-band midpoint test is near on all three, but the RSI gate means none of this is actionable today. "Wait" here means concretely: hold off on any entries and re-check the RSI readings as the pullback the thesis anticipates develops. If the market-wide selloff the idea describes deepens enough to drag momentum down toward the 40 line while each stock holds its trend structure, the entries can arm. If the RSI never gets there and prices simply run, the setup expires unfired — that is an acceptable outcome, not a failure. Once an entry triggers, the trade framework caps risk at roughly 2.4% of the position with a fixed-risk sizing method, takes profit at about 4.8%, and also exits on a 90-bar holding limit, a test of the second resistance level, or a break of the 61.8% retracement level. That yields an effective reward-to-risk of about 2-to-1 per position, with a maximum position size of 25% of the book.

The core idea — that Microsoft and Costco are strong enough to lead while the broader market sells off on rate fears — is well supported by the latest fundamentals. Microsoft's fiscal Q4 (ended June 30, 2026) delivered $90.0B of revenue, up 17.7% year over year and 8.6% from the prior quarter, with net income of $35.8B and a net margin near 39.7%. Free cash flow jumped 24.3% quarter over quarter to $19.6B. Those results rank in the top 1% of its Information Technology peer group for free cash flow and near the top for operating margin at 45.1%, per the peer percentile data. Per the MarketWatch report from September 25, 2026, the stock is heading for its highest close of the year on the AI narrative — a stock making new highs while the index falls is exactly the relative-strength behavior the thesis is built on. Costco supplies the defensive leg. Its fiscal Q3 (ended May 10, 2026) showed revenue of $70.5B, net income up 7.7% sequentially to $2.19B, and a net margin that improved to 3.11% from 2.92%. Full fiscal-year 2025 figures (period ended August 31, 2025) show $275.2B of revenue growing 8.2% year over year — faster than roughly two-thirds of Consumer Staples peers — with a 27.8% return on equity that lands in the 88th percentile of its sector. Free cash flow sits in the 96th percentile among 142 peers. Per the MarketWatch report from September 24, 2026, Costco beat profit expectations, helped by tariff refunds — a fresh catalyst consistent with the idea's claim that Costco is beating while the tape is ugly. The dividend records reinforce the quality argument from both directions. Microsoft has grown its annual dividend about 9.6% per year, most recently paying $0.91 quarterly (ex-date August 20, 2026); Costco's annual…
