All 18 factors for QQQ
FactorQQQPointsWhat it is
Plays in67%67The share of the plays you count that hold it now.
Analysts' upside––How far analysts' average 12-month target sits above the price (3+ analysts). −20% scores 0, +50% full marks; at most 50 while the price is below its 200-day average, since targets lag a falling price.
Analysts' rating––The analysts' average recommendation: strong buy scores 100, hold or worse 0.
P/E––Price over the last four quarters' earnings per share. Lower ranks higher; a loss scores 0.
Forward P/E––Price over next year's expected earnings. Lower ranks higher; an expected loss scores 0.
PEG––P/E divided by expected earnings growth. Lower ranks higher; around 1 is often read as fair for the growth.
Price to sales––Market value over the last 12 months' revenue. Lower ranks higher.
Price to book––Price over book value (assets minus debts) per share. Lower ranks higher.
Dividend yield––Dividends over the last year as a share of the price. Higher ranks higher; no dividend scores 0.
Earnings growth––Earnings per share over the last four quarters against the four before (the latest quarter on a year earlier where filings aren't available). Higher ranks higher.
Revenue growth––Revenue over the last four quarters against the four before (the latest quarter on a year earlier where filings aren't available). Higher ranks higher.
Profit margin––Net profit as a share of revenue. Higher ranks higher.
Return on equity––Profit as a share of shareholders' equity. Higher ranks higher.
Debt to equity––Debt against shareholders' equity. Lower ranks higher; negative equity scores 0.
Off the high−2% from its 1-year high93How far the price sits below its highest close of the last year: 100 points at the high, none at 30% or more below. The exit rule: a stock that keeps falling loses points whatever else it has going for it.
Trend+11% vs 200-day73How far the price sits above its 200-day average. Higher ranks higher.
1-year momentum+24%60The price change over the last 12 months. Higher ranks higher.

The most accurate play in each family

Each family's play whose calls went the right way most often, tested on 351 stocks since 2005, and what it says about QQQ now.

A call is right when the stock rose after an in call or fell after an out call. Trend plays are built to take many small losses for a few big wins, so their hit rates run lower; being right often isn't the same as making the most money. How we test a play.

Each candle is one trading day: the box spans the open and close, the thin line the day's high and low. Hollow boxes closed up, filled boxes closed down. Toggle the averages to see the trend the plays read. Dots above the candles mark news and company filings: hover or tap one to see the story and how the stock moved from the last close before it, against the market on the same days.

One row per play, grouped by family. When most rows turn green at once, the trend is broad. When they split, the plays disagree and the stock is usually chopping sideways.
