Intermarket confirmation for long-duration bond-fund timing

A zero-coupon fund as the bond proxy

A 30-year-maturity zero-coupon Treasury fund can stand in as a proxy for the 30-year Treasury bond. The fund pays only at maturity, so its price swings exaggerate those of the cash-bond market.

That zero-coupon-exaggeration is why the fund is the index-proxy here: a more tradable vehicle chosen to stand in for a less convenient benchmark, with built-in volatility for timing drills.

Money-market maturity as a rate-expectation map

Money-market managers shorten average portfolio maturity when they expect higher interest rates and lengthen it when they expect lower rates. Money-market-maturity is the average days-to-maturity of those portfolios, read as a weekly map of short-rate expectations among cash managers.

Money-market maturities lengthened from December 1990 as policy rates were cut, found support near 52 days, and shortened from January 1992 as recovery and higher-rate expectations returned. The path of money-market maturities tracked the 90-day Treasury bill yield, and both downtrends stalled in January 1992.

Dollar-index confirmation

A rising U.S. Dollar Index is often read as currency-market expectation of higher long-term U.S. rates. Dollar-index-confirmation uses that index as an external check on whether currency traders share the long-rate expectation implied by bond yields.

In the documented period the dollar’s peak occurred near the peak in the 30-year bond yield, and a later dollar decline accompanied falling bond yields.

Bullish-consensus extremes

A bullish-consensus-extreme is a published share of bond bulls treated as a contrarian threshold. Bond Bullish Consensus near 70 percent is treated as an optimism extreme that often precedes a top, while readings below 43 percent are treated as a pessimism extreme that usually marks a bottom. The pessimism threshold was described as the more consistent of the two.

After December readings above 60 percent, a 67 percent bulls reading on January 11, 1991 marked a sentiment peak that preceded higher yields. Later pessimism in June and July, confirmed by a contemporaneous dollar-index top, preceded a bond-price advance.

The ten-minus-four oscillator

On the volatile zero-coupon fund, a ten-minus-four-oscillator is the difference between a 10-week and a 4-week moving average. It is acted on at direction changes rather than zero-line crosses. Those turns aligned with fund price reversals.

Editorial combination of the three checks

The documented sequence supplies the separate alignments: the January 1991 bullish-consensus-extreme, later mid-year pessimism confirmed by a dollar-index top, the 1990–1992 money-market-maturity path beside the 90-day bill yield, and oscillator turns that aligned with reversals on the fund.

Editorial interpretation: stay flat unless money-market-maturity, dollar-index-confirmation, and a bullish-consensus-extreme describe the same rate-expectation regime. When they agree, treat a change in direction of the ten-minus-four-oscillator as the cue to enter, reverse, or abstain. Requiring all three checks to agree before an oscillator turn is acted on is an editorial combination rule, not an archive instruction.
