FLOWS

The half-year close moves money on its own

June 30 ends H1. After a strong half, funds rebalance, and that triggers mechanical selling.

THE IDEA

66 / 34

↑ where a 60/40 portfolio lands after a strong half

When stocks rise more than bonds, a portfolio built for 60% equities / 40% bonds ends up with more equity weight than it wanted. To return to target, it sells stocks and buys bonds, with no news changing at all.

DATA

THE DRIFT

~+9%

~+9%

▲ estimated S&P 500 gain over the half

A half like this inflates the equity weight in every portfolio. The end-of-June rebalance is when it gets put back in place.

Approximate. The more stocks rise over the half, the more equity funds must sell to rebalance.

REBALANCE
Adjusting weights to return to the portfolio's target mix.
WEIGHT
The percentage an asset takes up within a portfolio.

QUOTE

AUTHORITY

Flows, not fundamentals

At quarter-end, a good share of orders follow rebalancing rules, not a view on the market. It's flow, not fundamentals.
Ronfy Analysis · Editorial

In the last days of the quarter, part of the move is calendar, not conviction. Don't confuse the two.

FLOW
Buying and selling driven by rules or calendar, not analysis.
FUNDAMENTALS
A company's value based on its earnings and balance sheet.
CONVICTION
A position taken on a clear view of the asset.

Six months higher. Each leg up leaves funds with more equity than their rule allows. That's what gets corrected at month-end.

Illustrative path of the S&P 500 over the half. A steady climb means more equity weight than planned.

TWO SIDES

SELLS vs BUYS

What rebalancing sells and buys

WHAT IT TENDS TO SELL

The half's winner

  • Stocks, especially the biggest gainers (tech and megacaps).
  • Whatever now sits overweight versus the portfolio target.
  • Selling that can stall the leaders even on good news.

WHAT IT TENDS TO BUY

The laggard

  • Bonds, which returned less than stocks over the half.
  • Underweight assets that have fallen below target.
  • Buying that can put a floor under the most beaten-down names.

The rebalance moves money from the half's winner to the laggard. Mechanical, not emotional.

MEGACAPS
The largest companies by market value (the big tech names).
UNDERWEIGHT
An asset holding less weight than the portfolio target sets.

EXAMPLE

PORTFOLIO

A 60/40 portfolio after the half

STOCKS: 66%BONDS: 30%CASH: 4%EQUITIES66%
STOCKSTarget 60%: now sits overweight.66%
BONDSTarget 40%: has fallen below.30%
CASHReserve earning ~5% while it waits.4%

To return to 60/40, the fund sells ~6 points of stocks and buys bonds. That adjustment is the quarter-end flow.

This is NOT advice. It's how a 60/40 target portfolio drifts when stocks run.

EQUITIES
Stocks: ownership stakes in listed companies.
CASH
Money or equivalents available immediately.

Did you know the calendar moves stocks too?

Telling flow from fundamentals keeps you from reading a mechanical sale as a fear signal.
