AIQ Signal Divergence

Both carry 3 more signals that do not separate them: Death Cross Active, Keltner Channel Breakout, MACD Bullish Crossover.

COST leads the comparison while carrying a conflicted signal state, which is one reason the stability rating is not higher.

Price vs model alignment

Whether the latest session's price move confirms what the model did over the same session, or contradicts it.

COSTNo material change

Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +0.37%, AIQ 0 points).

PEPConfirmed strength

Price and the AIQ Score both moved up over the latest session (price +0.51%, AIQ +1 points).

What would flip this result

A state, not a forecast. These are the specific, observable changes that would reverse the verdict — not a price prediction.

  1. 1PEP closes the Momentum gap — currently 34 points behind, the largest single contributor to COST's edge.
  2. 2PEP's Death Cross Active resolves — a bearish trend rule currently active against it.
  3. 3COST's conflicting signal state resolves bearish — it currently carries 2 bullish and 2 bearish rules at once.
  4. 4A regime shift changes factor weighting — Quality and Value carry the heaviest weights in the composite, so a rotation toward either would move the result most.

Straight answers

Which is better, COST or PEP?

On the Algovestiq AIQ Score, COST is the stronger of the two as of Oct 21, 2026, scoring 62 against PEP's 56. The edge comes from momentum and risk resilience. PEP is not without a case — it holds the better value profile, which matters more if that is the objective you are optimizing for. This is a systematic score, not a recommendation: it ranks the two on the same evidence, it does not know your holding period or tax position.

Is COST or PEP the better buy right now?

COST carries the stronger systematic profile as of Oct 21, 2026, and the comparison is rated Fragile — 3 of 6 covered evidence groups agree. A Fragile rating means the conclusion is sensitive: only 3 of 6 covered evidence groups agree. Treat the lead as provisional.

Why does the AIQ Score favor COST over PEP?

The composite weights Quality, Value, Momentum and Risk Resilience. COST leads Momentum by 34 points; COST leads Risk Resilience by 22 points; PEP leads Value by 16 points. Where the two split, the factor with the larger weight carries the result.

Which has more analyst upside, COST or PEP?

Analyst price targets imply +11.3% upside for COST and +11.6% for PEP. The model and the Street agree here, which is a broader base of evidence than either alone. Analyst targets are expectations, not predictions, and dispersion matters as much as the midpoint.

Which is better value, COST or PEP?

PEP is the better-valued of the two on the peer-relative Value factor. PEP on the peer-relative Value factor, by 16 points. The Value factor reads valuation relative to sector peers and to the company's own fundamental quality, so it is not the same as simply having the lower multiple.

Which has stronger growth, COST or PEP?

COST on combined revenue and EPS growth. Growth here is measured on reported revenue and earnings, not on forward estimates — it describes what the businesses have delivered, not what the Street expects next.

Which has stronger momentum, COST or PEP?

COST on the Momentum factor, by 34 points. Momentum is one of the four weighted factors in the AIQ composite. It has documented persistence over three- to twelve-month horizons, which makes it a timing input rather than a reason to hold something indefinitely.

Which is riskier, COST or PEP?

COST is the more resilient of the two, so the other name carries the higher downside risk. COST on Risk Resilience, by 22 points. Risk Resilience is a weighted factor in the composite; position sizing usually responds to it more usefully than the buy/avoid decision does.

Is COST more profitable than PEP?

PEP leads on the comparable margin measures — gross margin 12.9% vs 54.2%; operating margin 3.8% vs 15.3%; ttm roe 28.3% vs 50.7%.

Is COST's lead over PEP getting stronger or weaker?

COST lead: Stable — the AIQ differential has held near 6 points over 30 sessions. This is measured from 120 daily comparison snapshots between 2026-06-21 and 2026-10-20. The lead has changed hands 4 times in that window, most recently on 2026-09-25, when COST moved ahead of PEP.

What would change the COST vs PEP verdict?

The result is a state, not a forecast, so it changes when the underlying evidence changes. Concretely: PEP closes the Momentum gap — currently 34 points behind, the largest single contributor to COST's edge; PEP's Death Cross Active resolves — a bearish trend rule currently active against it; COST's conflicting signal state resolves bearish — it currently carries 2 bullish and 2 bearish rules at once; a regime shift changes factor weighting — Quality and Value carry the heaviest weights in the composite, so a rotation toward either would move the result most.

What do the current signals say about COST and PEP?

COST: 2 bullish / 2 bearish, conflicted. PEP: 2 bullish / 3 bearish, conflicted. A conflicted state means bullish and bearish rules are active on the same name at once — the technical evidence is not pointing one way, and a decision taken on it carries more timing risk. The most decision-relevant rule on COST is Death Cross Active (bearish, long horizon). On PEP it is Death Cross Active (bearish, long horizon).

How this comparison is scored

The Algovestiq AIQ Score composites four factors — Quality, Value, Momentum and Risk, each carrying a fixed weight. Sentiment is reported separately as SentimentPulse and is not folded into the composite. Scores refresh every trading day, and this page regenerates from the latest snapshot rather than being written once.

The verdict names a leader, states how broadly six independent evidence groups agree, and rates how durable that conclusion is given the score gap, its recent trajectory and the current signal state on both names.
