Is everything at its peak? How to invest when markets feel “white hot”

“Everything is at its peak… how are we supposed to hedge against a drop if everything is white hot?”

You’re not the only one feeling this. US equities have roared, gold has run, and crypto is back in the headlines. When everything looks expensive, fear of buying the top wrestles with fear of missing out. For UK investors, the answer isn’t to guess the top – it’s to build a portfolio that survives a range of outcomes, and to be choosy about where you pay up.

Below, I’ll translate that Reddit anxiety into a practical playbook: what “hedging” really means, tools UK investors can actually use, and where value may still exist.

Valuation context: expensive doesn’t mean uninvestable

High prices and strong momentum can co-exist with decent future returns – but starting valuations matter. US mega-cap tech looks rich on most metrics, which concentrates risk. By contrast, broad UK equities have lagged for years, leaving pockets of better value and higher dividend yields.

Three quick observations for a UK audience:

  • Concentration risk is real – a handful of US names drive a big slice of global indices. Diversify beyond a single growth trade.
  • Valuation dispersion is your friend – UK, Japan, select emerging markets, value and small-cap factors are cheaper than US mega-cap growth.
  • Currency matters – a stronger pound can ding overseas returns. You can mix GBP-hedged and unhedged ETFs to manage this.

What hedging actually is – and what it isn’t

A hedge reduces the impact of a bad outcome. It usually has a cost, either explicit (option premiums) or implicit (lower expected returns). The art is deciding which risk you most want to hedge: equity drawdowns, inflation, recession, or currency.

Common confusion: cash is not a “waste” if it pays a decent rate and gives you the ability to buy when others are forced sellers. It’s both a volatility dampener and a call option on future opportunities. The trick is sizing it sensibly.

Practical hedges UK investors can actually use

Hedge / Tilt What it does Main costs or risks How to access (UK)
Cash and short-term bills Cuts portfolio volatility and drawdowns Opportunity cost if markets rip higher Cash ISA, money market funds, short-dated gilt ETFs
Long-duration gilts Often rally in recessions and equity sell-offs Interest-rate risk if yields rise; correlation can flip Gilt funds/ETFs, direct gilts in brokerage
Index-linked gilts Protects purchasing power when inflation surprises Real yield sensitivity; can be volatile Index-linked gilt funds/ETFs
Protective puts / collars Hard floor on losses over a period Options cost; complexity; needs discipline Options-enabled brokers; some structured products
Minimum-volatility or quality equity ETFs Historically smaller drawdowns May lag in strong growth rallies UCITS ETFs on LSE tracking min-vol/quality indices
Trend-following funds Can hedge prolonged bear markets Can whipsaw in choppy markets Managed futures UCITS funds
Gold Insurance against currency and policy shocks No cash flow; can fall in liquidity squeezes Gold ETCs, physical coins/bars
Currency hedging Reduces FX swings on overseas holdings Hedge cost can eat returns over time GBP-hedged share classes of global ETFs

Is anything undervalued right now?

“Undervalued” isn’t a single thing – it’s a basket of places where expectations are low and cash flows are underpriced. Today that often means:

  • UK small and mid caps – unloved, less covered by analysts, and more sensitive to a domestic recovery. Volatile, but fertile for stockpickers and active funds.
  • Value and quality factors – cheaper valuations and balance sheet strength can help if rates stay higher for longer.
  • Selected cyclicals and energy – cash-generative, often on lower multiples. Do your homework on balance sheets and project risk. For instance, I recently covered a contrarian UK-listed energy explorer here: Rockhopper Exploration: 2024 results and Sea Lion update.
  • Investment trusts on discounts – many UK-listed trusts trade below their net asset value, offering a margin of safety if discounts narrow. Check leverage and fee structures.

None of this guarantees outperformance next quarter. It simply tilts you away from the “everything that already went up” risk concentration.

Smart portfolio construction when prices look frothy

Barbell your risk

Combine very safe with selectively risky. For example, hold a meaningful chunk in cash/short gilts, and pair it with higher-expected-return assets you truly want to own for 5+ years (UK small caps, global value, quality). This avoids the mushy middle and keeps you invested without overpaying everywhere.

Rebalance on a schedule

Pre-commit to a rebalancing rule (quarterly or semi-annual). When equities run, trim back to target and top up your hedges. When markets drop, your cash and bonds are the dry powder to buy quality assets at better prices. Simple, boring, effective.

Use tax wrappers to boost after-tax returns

In an expensive world, tax efficiency is a free source of alpha. ISAs and SIPPs improve net returns and give flexibility to rebalance without capital gains friction.

Size your bets, don’t time the top

If you’re uneasy, reduce position size rather than going to zero. Pound-cost average new money. Make incremental shifts towards value, quality and non-correlated hedges instead of one big market call.

Risks and realities to keep in mind

  • Hedges can hurt when the market grinds higher – that’s the price of insurance. Judge them over cycles, not months.
  • Stocks and bonds won’t always diversify each other – 2022 reminded us correlations change. Mix duration, inflation protection, and alternatives.
  • Beware complexity creep – if you can’t explain the hedge, you probably don’t need it. Start with cash, gilts, and simple factor tilts.

Bottom line: build resilience, not bravado

When “everything is high”, you don’t need clairvoyance. You need a resilient mix: some cash, some duration, some inflation protection, diversified equities tilted away from the most expensive corners, and a rule-based rebalancing habit. If you insist on timing, do it with position sizing and pace, not hero calls.

That’s how you stay in the game, keep optionality, and avoid paying peak prices across the board. Hot markets pass. Good process endures.
