Selloff into midterms plus a make-or-break Fed week — buy the dip ahead of a historically strong post-election stretch

Verdict: the seasonal dip-buy thesis is plausible, but nothing has confirmed it yet — wait

Our stance over the near-term event horizon is wait: the post-Election Day seasonal argument (a claimed 15.5% average S&P 500 return in the nine months after Election Day since 1950, per the MarketWatch piece the idea cites) is directionally attractive, but no entry condition has fired — SPY closed at $761.37 against a $765.89 EMA(50) and its RSI(14) sits at 36.5 versus a required move above 40. The strongest point for the trade is the quality of what you would own: the fund's top ten holdings (36.3% of weight) show 53.7% revenue growth and 38.0% net margin, with a durable dividend stream — VOO's trailing distributions are $7.43 per share, growing 5.57% a year. The strongest point against is that the seasonal claim is unverified and the mechanical rule-set has no measured track record at all, because inconsistent SPY price bases and VOO records meant historical performance could not be computed across any tested window; a 2.0% stop inside a week containing a Fed decision and an inflation print risks being shaken out by the very event volatility the thesis expects. The index is also really a megacap-AI bet (technology 38.5%, NVIDIA 7.5%, Apple 6.6%), so one guidance cut matters more than any calendar. What flips the verdict: a daily RSI(14) cross above 40 with the close back above the 50-day EMA turns this actionable, while a decisive close below the $749.72 first support (SPY) turns it into a trend-break, not a washout.

Trade now: wait for the momentum cross — the seasonal thesis alone is not an entry

The answer for today is wait. The idea's business thesis — buying an election-season dip in broad US index funds ahead of a historically strong post-Election Day window, with a claimed 15.5% average S&P 500 return over nine months after Election Day since 1950 — is directionally attractive and, per the idea, not dependent on which party wins. But the thesis and the entry conditions are separate questions, and today only the thesis side is in place. Neither SPY nor VOO meets its entry rules: SPY closed at $761.37 versus a $765.89 EMA (50) threshold, and its RSI (14), a 0-100 momentum reading where below 40 signals weak momentum, sits at 36.5 versus a required move above 40. The dip the idea wants to buy is happening; the momentum turn that would confirm the washout is ending has not. The horizon here is near-term event-driven: this week's Fed meeting and inflation print could push stocks lower in the very short term, per the idea, which is exactly the weakness the entry rules are designed to buy into. The pivotal condition is a daily RSI (14) close back above 40 alongside a reclaim of the 50-day EMA — a sign the dip is stabilizing rather than deteriorating. The downside that matters: SPY has already fallen about 2.4% from its range high, and its nearest support sits at $749.72, roughly 1.5% below the last close; a decisive break of support would argue the dip is a trend break, not a washout. What "wait" means concretely: hold off until either the BB/EMA/RSI rules trigger (RSI crossing above 40 with price above the EMA 50) or the pullback-support rules trigger (a daily low touching the first support level while the close holds above it). Until one of those fires, the seasonal argument remains an unconfirmed hypothesis. Scope note: because SPY's raw and adjusted price records were inconsistent and VOO's price/volume records were inconsistent, historical performance for this exact rule-set was not measured — so the entry is being judged on its stated logic, not on verified backtest results. ### Technical details Entry rule set (daily bars, long-only, SPY and VOO mirror rules). Each of the first two entries requires all of: the lower Bollinger band (20-day, 2 standard deviations) reading below the 40 threshold, close above the 50-day EMA, RSI (14) crossing above 40, and (for the tighter top-ranked variant) the daily low touching the nearest support level. SPY (last close $761.37, observed 2026-10-25 daily data): - Lower Bollinger (20): current reading $770.25, threshold 40 — not met, far from trigger. - Close above EMA (50): $761.37 vs $765.89 — close, about $4.52 (0.6%) below trigger. - RSI (14) crossed above 40: current 36.5 — not met, about 3.5 points away. - Nearest support: $749.72; nearest resistance: $760.8 (price is essentially at resistance). VOO (last close $698.58): - Lower Bollinger (20): $707.77 vs threshold 40 — far from trigger. - Close above EMA (50): $698.58 vs $702.63 — about $4.05 (0.6%) below trigger. - RSI (14): 35.0 vs required cross above 40 — about 5 points away. - Nearest support: $689.27; nearest resistance: $699.78. Exits (both tickers): take profit if RSI (14) rises above 70 (overbought) or after 180 daily bars held; take profit at the 127.2% Fibonacci extension or at +4.0% unrealized gain; stop loss on a close crossing below the second support level or at −2.0% unrealized loss. Position sizing: fixed-risk at 2.0% risk per position using the second support as the stop reference, capped at 25% of capital per position. At the stated −2% stop and +4% target, the reward:risk is 2:1 before costs. Reward:risk to the 127.2% Fibonacci extension target and second-support stop cannot be computed today because no entry has occurred and the retracement anchor levels are not yet defined for an active setup.

A 76-Year Seasonal Pattern Meets Underlying Earnings Strength

The bull case rests on a long-documented seasonal tailwind for the S&P 500 plus an index whose underlying constituents are currently growing earnings fast enough to justify owning it through event-week noise. The strategy itself is a rule-based dip-buying framework on SPY and VOO, so the question is whether the market's underlying fundamentals support buying weakness — and on the look-through numbers available, they plausibly do. ### The post-election seasonal claim is the thesis anchor The idea cites, per the MarketWatch piece published October 25, 2026, that since 1950 the nine months after Election Day have averaged a 15.5% S&P 500 return, and that the pattern has held regardless of which party won. If that seasonal regularity is real and not a small-sample fluke, it implies the current selloff is more likely a washout than a trend break. The causal chain is political-uncertainty resolution: once the election passes, a major source of risk premium comes out of equity prices, and investors re-risk into year-end. This supports the idea's stated direction of buying weakness rather…
