Weekly Quality Momentum

Quality Momentum, rebuilt every week so it reacts faster.

How it works

Weekly Quality Momentum holds 10 of the 500 most actively traded US stocks: those with the strongest price trends over the past year, among companies that generate cash and whose profitability is improving. It puts more money in the stronger trends and rebuilds the portfolio every week. Each rule is listed below in the order it is applied.

The rules, step by step

  1. When it decides. After the market closes on the last trading day of each week (usually Friday), using that day’s closing prices and only information available by then.
  2. The stock pool. US-listed common stocks and ADRs, not traded over the counter, closing at $5 or more. Each must have traded at least $10 million a day on average over 20 trading days at this decision and one and two months (21 and 42 trading days) before it. Of those, the 500 with the highest 20-day average trading value form the pool.
  3. Cash flow. Keeps only companies whose latest quarterly report, filed by the decision day, shows positive free cash flow.
  4. Improving profitability. Keeps only companies whose gross margin in the latest filed quarter is higher than in the same quarter a year earlier (as first reported).
  5. No sudden spikes. Skips any stock that rose more than 40% over the last month (21 trading days).
  6. The ranking. Ranks the remaining stocks by 12-1 momentum: the price change from twelve months ago (252 trading days) to one month ago (21 trading days), using prices adjusted for splits and dividends. The latest month is left out on purpose.
  7. The selection. Takes the 10 highest-ranked stocks, with at most two from any one industry sector: when a sector is full, the next-ranked stock from another sector takes the place. Stocks already held get no preference; each rebuild starts from the ranking.
  8. How much in each. In proportion to each stock’s 12-1 momentum: a stock up 80% gets twice the money of one up 40%. (Momentum below 1% counts as 1%.)
  9. The trades. Made at the next trading day’s closing price: stocks no longer selected are sold, new ones bought, and those that stay are resized to their new amounts. Every buy, sale and resize pays 0.10% of the amount traded.
  10. Between rebuilds. No trades. The holdings’ shares of the portfolio drift as their prices move until the next decision.

These rules are frozen (rules version 1) and are exactly what the record uses, every day since go-live and throughout the backtest. Changing any of them would make a new strategy with its own record. Key terms explained.

What to expect: Quicker to follow new leaders, and trades more often than the monthly strategies.

What would your money have done?

The amount you picture putting in. It only scales the dollar figures: the percentages are the same for $1,000 or $1,000,000.
How much of the account follows the strategy. The rest sits in BIL, a fund of US Treasury bills that mature in 1 to 3 months: close to cash, earning short-term interest. Every time the strategy rebuilds, the account is put back to your split. With 70/30, if the stocks have risen, some of the gain moves into T-bills; if they have fallen, some T-bills are used to buy stocks. A smaller strategy share means smaller falls and smaller gains.
Hindenburg ruleThe best rule from the Hindenburg research: when more than 2.5% of US stocks over $5 make a new 52-week high and more than 2.5% a new 52-week low on the same day, with SPY above its 50-day average, and the split also shows among companies worth more than $300 million (more than 3.0% at new highs and more than 2.0% at new lows) and in at least 3 sectors at each end (more than 2.0% of a sector's stocks), half of the strategy part moves into T-bills at the close six trading days later, and returns 31 trading days after the last such day. Every move appears in the ledger and pays 0.10%. Backtest before go-live, applied day by day after it.
The day your pretend account starts. “Since go-live” counts only the time the strategies have run live, each decision made at that day’s close with the rules unchanged. Earlier periods are a backtest: the same rules applied to past prices.

The account, as a ledger

The strategy shown as one account that started with $10,000 on Nov 1, 2017 (change the amount above) and followed every trade. Shares are fractional; share counts include stock splits and reinvested dividends. Gains are measured on average cost. With a split chosen above, part of the account sits in BIL (a 1–3 month T-bill fund) and is put back to the split at every rebuild: each move is one BIL row below, and it buys or sells the same slice of every stock held.

What it holds now

At the close of Oct 16, 2026. It decides after the close on the last trading day of each week and trades at the next day's close. The weights drift with prices between rebuilds. This is the model’s position, published for education, not a recommendation to buy these stocks: a portfolio started today would differ in entry prices and results.
