The Midterm Calendar: a Q4 Switching Map Around November 3 — the 6.6% Historical Win Rate of Midterm-Year Q4s and Forward-Pricing Defence

The macro matrix: an event-dense fourth quarter

The final quarter of 2026 is being defined by three forces at once: yields, rate decisions, and elections.

Start with yields. On October 1, the US 10-year Treasury touched 5.34%, its highest since 2002; the 30-year reached 5.642%. The 10-year eased toward 5.25% on October 2, but T. Rowe Price’s David Clewell now calls a move toward 5.5%–6% “credible” — the market is already pricing 6%, a month after 5% fell. For MPF bond funds, that is a direct hit on duration risk, not background noise.

Then the rate path. A week ago, CME FedWatch put the odds of an October 28 hike at 64%. One soft jobs report later — unemployment unexpectedly up, average hourly earnings rising just 0.1% against a 0.3% forecast, 12-month wage growth at 3%, its lowest since May 2021 — those odds collapsed to 14% within a week. The market now bets on a hold in October and a 75% chance of a cumulative 25bp hike by December 9. Dallas Fed President Logan said on Thursday that rates still need to rise “an additional 50 basis points or more”. Disagreement over the policy path is Q4 volatility fuel.

Then the technical split. The S&P 500 closed October 1 at 7,651.54, near record territory — but that is a Magnificent-Seven mirage (our October 3 piece: 75–78% of constituents fell in September). The Hang Seng plunged 2.7% on October 2 to 23,956.32, its lowest since July and down 3.7% for September, with southbound Stock Connect shut for Golden Week.

The third force is politics. November 3 (Tuesday) brings the US midterm elections: all 435 House seats and 35 Senate seats. Republicans hold the Senate 53–47 and cling to the House 219–213, with three vacancies — Democrats need a net gain of just three House seats and four Senate seats to flip control. A Reuters/Ipsos poll published September 21 put Trump’s approval at 32%, with the congressional generic ballot at 43% Democrat versus 35% Republican. Add the mid-decade redistricting wars and the escalating Iran war (another US carrier dispatched, Brent still above US$100), and the uncertainty premium is already in the price.

Matrix verdict: risk-neutral leaning risk-off. Yields are a headwind, the policy outlook is a variable, the election is an uncertainty event. Direction is not worth betting on; discipline is.

Backtest and win rate: the Q4 statistics of midterm years

History is unusually clear here.

J.P. Morgan Asset Management’s long-run data (since 1937): in midterm years, the S&P 500 averages a 9.2% full-year total return, below the 13.3% of non-midterm years. The weakness concentrates before the election — the first three quarters average slightly negative. But the fourth quarter flips: midterm-year Q4s average +6.6%, more than double the 2.9% Q4 average across all years (Bespoke, since 1928).

Capital Group’s data (since 1950) goes further: the 12 months after a midterm average +15.4%. And party analysis going back to 1933 shows double-digit average returns under unified government, split Congress, and opposition-controlled Congress alike — markets price earnings and rates, not party colours.

One execution-critical detail: the rebound has often begun roughly a month before election day. Investors who step aside to dodge the event have historically missed the start of the recovery.

Translating percentages into human terms (illustrative, using the HK$343,242 average balance from MPF Ratings’ September 24 report):

• The average midterm-year Q4 of +6.6% ≈ HK$22,654 — about 4.5 months of contributions at HK$5,000 a month.
• The average post-election 12 months of +15.4% ≈ HK$52,859 — about 10.6 months of contributions.
• Conversely, midterm years lag non-midterm years by 4.1 percentage points on average ≈ HK$14,073 — the price of pre-election turbulence.

But history gives win rates, not guarantees. 2026 is not a template year: a Fed in the Warsh hiking regime, a 10-year above 5%, an oil shock from the Iran war — this combination has appeared in zero of the roughly 22 midterm samples. Statistics tell you what usually happens, not what must happen this time. Use win rates to set discipline, not to size bets.

The switching blueprint: a Q4 event calendar and allocation sandbox

First, lay out the calendar (Q4 2026, from a Hong Kong perspective):

The sandbox below uses a member in their early 40s, far from retirement, as the illustration (illustrative only, not advice; adjust to your own risk tolerance):

First, rebalance before chasing. US equity funds are +10.1% year-to-date, Asia equity funds +24.5% (GUM). If your North American equity weight has drifted 10 percentage points above target on gains, trim that 10pp (about HK$34,324 on the average balance) back to target and into laggards or a global equity fund. That is discipline, not forecasting — and the midterm-year Q4 record rewards those who stay invested, not those who trade in and out.

Second, keep bond exposure short-duration in mindset. In a world of 5.25% tens and 5.64% thirties, long-duration bond funds still carry price risk — 2022 is the precedent (the HSBC Age 65 Plus Fund fell 13.21%), and an ~80% bond allocation is no shelter in a hiking regime. For members under 50, stage in short-duration or conservative funds rather than adding long bonds to bet on a reversal.

Third, fold the annual ECA switch into the Q4 calendar. The Employee Choice Arrangement allows one switch per calendar year; a December switch plus the January 1 reset permits another. Rather than switching around the election, spend the year’s free transfer where it counts: move balances from high-FER schemes to the market’s lowest-FER plans and lock in a certain 0.5–1 percentage point a year — money that requires no election forecast.

Fourth, the conservative fund is a car park, not a destination. Parking there over election week is understandable, but remember two numbers: conservative funds annualise roughly 1.2–1.5% over ten years against 1.9% underlying inflation in August — a negative real return — and the rebound often starts a month before the vote. Park too long and you park through the recovery.

Forward-pricing defence: the no-switch zone list

MPF switches execute at unknown forward prices (T+1/T+2) — submit after seeing the November 3 results and you buy the post-result NAV. The event itself is never tradeable; only the discipline around it is. Q4’s no-switch zones:

• Two days around the October 27–28 FOMC: in the post-forward-guidance era (Warsh has deleted it), statement wording can swing bond markets in a single session. Split large switches into batches and avoid the meeting day itself.
• The November 2–4 election window: results clarify through the morning of November 4 Hong Kong time. Any “wait for the result, then switch” plan is driving with the rear-view mirror under forward pricing. Finish switching by end-October, or wait until the second week of November when the dust settles.
• Around November 26 (Thanksgiving) and December 24–26: market closures pause fund pricing and stretch transit times — out-of-market risk and cash drag are amplified in holiday weeks. Leave small, non-urgent switches until after the holidays.
• The December 8–9 FOMC: the year’s final meeting, with a 75% priced chance of a hike that could either deliver or disappoint. Schedule any December switching before that week.

One year-round rule: every trustee’s daily dealing cut-off differs — check your scheme brochure before submitting. An instruction lodged after cut-off rolls to the next dealing day’s price, which in an event week means one more day of blind buying.

Elections pass, yields gyrate, but the 6.6% historical win rate belongs to one type of investor: those who arrive with a disciplined allocation, sit still through the event, and rebalance after it. The Q4 calendar is laid out. Execution is all that remains.
