When April Delivers 5% Gains, the Rest of the Year Has Never Been Negative. Here’s What History Says About May

Here is a pattern worth knowing as April winds down: When the S&P 500 gains 5% or more in April, the rest of the year has never finished negative. The sample is small, but the signal is clean. With April 2026 on track to be the second-best April for the S&P 500 since 1950 and SPY up 8.28% from April 1 through midday trading on April 28, the index has already cleared the threshold. The question for long-term holders is what that historically tends to mean for May and the back half of the year.

Below are the five strongest signals supporting a constructive setup, counted down to the most important one. We’re using SPDR S&P 500 ETF Trust (NYSEARCA:SPY | SPY Price Prediction) as the practical proxy for the index. Treat each as a tendency.

1. The Fed Has Already Pivoted

A more accommodative policy backdrop typically supports equity multiples. The Fed Funds upper bound sits at 4%, down 1 percentage point from 5% a year ago, after three consecutive 25 basis point cuts between September and December 2025. The 10-year Treasury yield has cooled to 4%, down from a March 27 peak of 4%. Lower funding costs and stable long rates remove a key headwind that punished growth equities through much of 2025.

2. Forward Earnings Just Hit a Record

Bull markets follow earnings, and the earnings curve is still rising. Forward S&P 500 EPS hit a record high of $344.30 last week, per Yardeni research. That matters because seasonal patterns work best when the fundamentals are cooperating. A rising forward EPS line means analysts are still revising estimates higher across the index. For retirement-focused holders, that is the variable that drives compounding over multi-year windows.

3. Buybacks and Analyst Targets Provide a Floor

Corporate buybacks are at all-time highs, which functions as a structural bid underneath the market. Layer on this: over 90% of S&P 500 stocks are still trading below their average analyst price targets despite the rally. That mismatch suggests Wall Street’s bottom-up models have not caught up with index-level price action, leaving room for further estimate-driven follow-through.

4. April’s Leadership Is Broad and Tech-Heavy

Quality of the rally matters. Tech stocks within the S&P 500 are up almost 20% in April, on track for the best monthly performance since 2002. With Information Technology weighted at 33% of SPY and top holdings led by NVIDIA at 8%, Apple at 7%, and Microsoft at 5%, the index’s largest engines are firing simultaneously. SPY’s one-month return of 13% through April 27 reflects that concentration working in investors’ favor.

5. The April 5% Rule Itself

This is the headline pattern. According to a BTIG morning note attributed to @Bluekurtic, when April gains 5% or more, the full-year return has historically always been positive. The follow-through is even more specific: the month of May after a 5%+ April has delivered a positive return in 9 out of 10 occurrences, a 90% hit rate. Looking at the most recent comparable window, SPY returned 22% from April 1, 2025 through December 31, 2025, a textbook example of the pattern playing out.

The countercurrents deserve weight. BTIG’s Jonathan Krinsky has warned the rally rubber band is stretched and likely snaps soon, with semiconductors at extreme overbought readings. The VIX at 18.02 has fallen 42% over the past month, hinting at complacency, and University of Michigan Consumer Sentiment at 53.3 sits in pessimistic territory below the 80 threshold. Prediction markets reflect that ambiguity. Polymarket’s May 2026 SPY market shows balanced probabilities across the $650 to $780 range, with $720 and $710 each priced at 0.535.

What It Means for Long-Term Holders

Seasonal patterns are tendencies. The April 5% rule has a clean track record, and the macro backdrop, including a record forward EPS reading, record buybacks, and an easier Fed, points in the same direction. A near-term pullback would not invalidate the historical signal. For retirement-focused portfolios benchmarked to the index, the lesson from prior cycles is to respect the pattern, plan for volatility around it, and let compounding do the work that timing rarely can.
