Momentum, value, quality — explained

Factor percentiles tell you where a stock sits versus everything else. Here's how to read them, and their limits.

"Is this a good stock?" is too vague to answer. Quantitative investors decompose the question into factors — measurable characteristics that have historically explained differences in returns. Three of the most studied are momentum, value, and quality.

The three factors, plainly

  • Momentum asks: has this stock been outperforming recently? Persistent strength tends to persist over intermediate horizons — one of the most robust findings in market research.
  • Value asks: how much business do you get per dollar of price? Cheaper stocks (by earnings, cash flow, or book value) have historically rewarded patience, though they can stay cheap for long stretches.
  • Quality asks: how durable is the underlying business? Stable margins, sensible leverage, and consistent profitability tend to hold up better when conditions worsen.

Why percentiles beat raw numbers

A P/E of 28 means nothing in isolation — expensive for a utility, cheap for a high-growth software name. Rankings fix this by scoring each stock against the rest of the universe. A value percentile of 87 means the stock screens cheaper than 87% of the comparison universe; a momentum percentile of 12 means weak recent performance versus nearly everyone else. iTrading Buddy computes momentum, value, and quality percentiles against a broad stock universe, refreshes them weekly, and shows them as a composite strip in every Pro research dossier.

Reading factor profiles

The combinations often say more than any single score:

  • High momentum + low value — a crowded winner. The trend is your friend until the multiple compresses.
  • High value + high quality — the classic "good business at a fair price" profile long-term holders hunt for.
  • High value + low quality — possibly cheap for a reason. The bear case deserves extra attention here.
  • High across all three — rare, and worth understanding why before assuming the market missed it.

Factors inform; they don't decide

Factor rankings are a lens, not an oracle — entire decades have favored one factor and punished another. That's why iTrading Buddy presents them inside the dossier next to the news, catalysts, insider activity, and the bear case, rather than as a standalone buy signal. The number tells you where a stock sits; the context tells you whether that matters right now.
