Investment and trading strategy research

Investment & Trading Strategies

Understand the rules, assumptions, risks and trade-offs behind different approaches.

Independent research on long-term investing, allocation, rebalancing, position size, trend rules, options structures and hedges. A strategy is a set of decisions you can review. It is not a promise of a return.

Strategy categories

Eight questions. Counts are published notes carrying that tag. A note can carry more than one tag. The count is not a score.

Long-term investing. Follow a funding and holding rule you can review.

Long-term investing

Buy and hold, a schedule of contributions, and dividends as a separate assumption from the price.

Objective. Follow a funding and holding rule you can review.

Limitation. A schedule does not stop a long decline, and it does not beat a lump sum on every path.

Allocation and rebalancing. Pull weights toward targets you set earlier.

Allocation and rebalancing

Target weights, a calendar, a band, and new cash that buys the light holding without a sale.

Objective. Pull weights toward targets you set earlier.

Limitation. Trading back to target does not identify the next winner, and it has a cost.

Position size and risk. Make a wrong exit cost a loss you already accepted.

Position size and risk

A loss budget, a stop distance, and a volatility estimate are three ways to write a quantity.

Objective. Make a wrong exit cost a loss you already accepted.

Limitation. The worksheet is not the loss if the exit is worse, or if several positions fail together.

Trend and momentum. Stay with a move the rule has already defined.

Trend and momentum

Filters and rankings that take exposure after a move has been measured.

Objective. Stay with a move the rule has already defined.

Limitation. A range produces whipsaws. A lookback chosen after the path is not a test.

Mean reversion. Trade the return to a line you defined.

Mean reversion

Entries that fade a move back toward a reference, often for a small distance.

Objective. Trade the return to a line you defined.

Limitation. The line can be the thing that changed. Costs are large when the target is small.

Options structures. Exchange a payoff for a premium.

Options structures

Covered calls, protective puts, collars and spreads as expiry shapes, plus what the shape leaves out.

Objective. Exchange a payoff for a premium.

Limitation. Premium is not free income. An expiry drawing is not tomorrow’s price.

Hedges. Transfer a named risk to a named contract.

Hedges

A contract used to offset an exposure, with basis, size and collateral written beside it.

Objective. Transfer a named risk to a named contract.

Limitation. A different month, grade or currency is a different risk. Collateral can force a reduction.

Diversification. Decide which risk is allowed to dominate.

Diversification

Weights, a risk budget, and the estimate of how holdings move together.

Objective. Decide which risk is allowed to dominate.

Limitation. Correlation is a window. Diversification does not remove losses.

Compare approaches

Dollar-cost averaging and a lump sum differ in when cash becomes exposure. A calendar and a band differ in when you trade. The lab extends that kind of comparison. It does not produce a probability of success.

Up to three approaches. The rows describe structure. They are not a ranking and they are not a return.

Structural comparison. Identical rows can be hidden. Hiding them does not make the remainder a score.
QuestionDollar-cost averagingBuy and hold
ObjectiveTurn arriving cash into exposure on a schedule.Keep a chosen exposure through declines unless the written rule says otherwise.
RulesInvest a similar amount on dates you choose. The unit count changes with the price.Define the holding and the condition that would make you sell. Do not add a forecast.
InstrumentsAnything you can buy in slices. Cash that is waiting is not yet exposed.Shares, funds, or other holdings you can actually keep.
HorizonThe length of the schedule, then whatever holding rule follows.Longer than a single news cycle. You set the review date.
ActivityOne ticket per date.Low, until the review or the failure condition.
CostsA cost on every ticket, plus any fee on cash that has not been invested.The spread and any commission at entry, plus ongoing fund or account charges.
AssumptionsThe schedule is funded. A steadily rising path favours investing earlier.You can fund the holding and tolerate a long drawdown.
RisksA falling path hurts the amounts already invested. The schedule does not stop that.A long decline. Concentration if one holding becomes the account.
What can break itTreating one assumed rate as proof the schedule beat a lump sum.A path that falls for longer than the patience you wrote down.

Long-term rules

A contribution is a funding decision. Rebalancing is a weight decision. A dividend is a company decision that may not be repeated. Inflation changes what a nominal balance can buy, and it is not a line in the contribution calculator unless you put it in the rate you assume.

The calculators illustrate a return you type, after a fee you type. Change the assumption and you are looking at a different picture.

Active rules

Trend, momentum, breakout and mean reversion are definitions of what recent prices mean. The entry you draw is not the fill. A spread, a gap and a thin book sit between the signal and the position. A stop is an instruction with its own failure mode.

Trend rule · The bill for activity · Position size

Portfolio construction

Weights, a volatility estimate and a correlation window are descriptions of a sample. Several funds can share the same large holdings. Currency can dominate a foreign weight that looked small in the home currency. Liquidity and counterparty risk do not appear in a returns correlation.

Options and hedges

A covered call sells upside. A protective put buys a floor and charges a premium. A collar does both. A futures hedge transfers risk only as far as the contract matches the exposure. Expiry drawings are not marks before expiry. This page does not reprint a contract multiplier.

How a rule changes the outcome you are looking at

Each pair is a difference of structure. The numbers, when you want them, are typed into the calculator named under the pair. Nothing here is a historical result.

A fixed cash loss does not shrink when the account does.

A percentage shrinks or grows with the capital you type.

Both are loss budgets. Neither is the loss you get if the exit is worse than the stop. The position-size calculator uses the budget, the distance and the multiplier you enter.

How to read a strategy before trusting it

Objective

What disappointment still counts as the rule having been followed?

Why it might fit

What exposure does the rule actually create? A story about the economy is not that exposure.

Evidence

Which universe, window and cost were in the test? If the rule was chosen after the path, the path is not a fresh test.

Cost

Spread, tickets, financing and the number of turns. A cost inside the fill is not added again.

Regime

Name the market that makes the assumption fail: a range for a trend rule, a trend for a fade.

Practice

Can you trade the size at a price near the one in the worksheet? A signal on a chart is not a fill.

Why a tested line can mislead

Look-ahead bias uses a fact the trader did not have. Survivorship drops names that failed. Trying many rules and keeping the winner describes the search, not the next path. Ignored costs turn a paper result into a different strategy. A later period is a stricter check, and it can still be a different regime.

This site does not run a backtest and it does not draw a synthetic equity curve as if it were history.

A fitted curve is not a record

Build a rulebook

Write the objective, the market, the horizon, the entry, the exit, the risk limit, the costs, the review and the condition that retires the rule. Copy it, print it, or download a text file. Clearing the form removes it from this page.

The answers stay in this browser. They are not sent to WiT Markets. A completed page is not a validation of the rule and it is not a statement that the rule will make money.

    A breakout level is a price on a chart, not a guaranteed fill

    How a breakout entry, a false break, and a stop beyond the range depend on liquidity at the moment the level is touched.

    • A stop or a stop-limit does not promise the price printed on the chart.
    • A false break returns inside the range and often pays the spread twice.
    • Size the loss from a worse exit than the line you drew.

    A calendar and a band are different instructions to trade

    How calendar rebalancing, a threshold band, and new contributions that do the buying without sales change turnover, drift and cost.

    • A date rule and a width rule trade at different times, so they incur costs on different paths.
    • Letting contributions fill the underweight holding avoids a sale until the band is still breached.
    • The rebalancing calculator uses weights you type. It does not predict the next winner.

    A contribution schedule and a lump sum take risk at different times

    How funding timing, cash that is not yet invested, and the path of prices change the comparison between regular contributions and investing available cash at the start.

    • The schedule changes timing. It does not, by arithmetic, beat a lump sum on a steadily rising path.
    • Cash that is still waiting is not exposed, and it is also not earning the market return you might type into a calculator.
    • Use the dollar-cost calculator with a return you assume. The label on the result is hypothetical.

    A covered call is a sale of upside, not free income

    What a covered call changes about a share you already hold: a premium received, a cap on the gain, and the shares’ downside still in the account.

    • The premium is received because the upside is sold.
    • Below the strike, the shares drive the loss. The premium only offsets a slice of it.
    • The payoff calculator draws the result at expiry from inputs you type. It is not the value of the contract tomorrow.

    A hedge can miss because the contract is not the exposure

    Why contract size, a different underlying, a calendar spread between months, and collateral can leave a hedge imperfect. No exchange specification is reprinted here.

    • The hedge ratio is a size you choose. It is not a promise the prices will match.
    • A different month, grade, or currency is a different risk.
    • Collateral can force a reduction before the hedge has done its job. The amount is on the contract and the firm, not on this page.

    A protective put and a collar buy a floor and charge for it

    How a long put under shares sets a floor in exchange for a premium, and how selling a call to fund that premium also caps the upside.

    • The floor is only as good as the strike, the expiry and the fill.
    • Funding the put by selling a call adds a cap.
    • A debit spread and a credit spread cap the gain and the loss in different directions. Neither is automatically limited in every account if the contract is not the one you think.
