AIQ vs Wall Street
The model and the Street disagree here: AIQ favors RIG, analyst targets favor SLB. That disagreement is the most useful thing on this page.
| Measure | RIG | SLB | Note |
|---|---|---|---|
| Implied upside to target | +15.9% | +24.3% | SLB has more room |
| Target dispersion | 0% | +37.8% | Lower is tighter analyst agreement |
| Consensus | Hold | Buy | Context, not a primary driver |
| Analysts covering | 2 | 12 | Higher coverage generally improves confidence |
The two are measuring different things. The AIQ Score reads current fundamentals, valuation, trend and risk; analyst targets price forward expectations. A divergence of this kind is either a contrarian opportunity or a sign the model is missing something already priced in — it is worth resolving before acting on either.
Analyst targets are expectations, not predictions. Dispersion matters as much as the midpoint.

Price vs model alignment

Price and the AIQ Score both moved up over the latest session (price +2.24%, AIQ +3 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.
- 1SLB closes the Momentum gap — currently 30 points behind, the largest single contributor to RIG's edge.
- 2SLB's Bollinger Band Squeeze turns directional — it is neutral today and would confirm a change in trend.
- 3RIG's conflicting signal state resolves bearish — it currently carries 2 bullish and 2 bearish rules at once.
- 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.

Which is better, RIG or SLB?
On the Algovestiq AIQ Score, RIG is the stronger of the two as of Oct 21, 2026, scoring 54 against SLB's 45. The edge comes from momentum and quality. SLB is not without a case — it holds the better risk resilience 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 RIG or SLB the better buy right now?
RIG 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 RIG over SLB?
The composite weights Quality, Value, Momentum and Risk Resilience. RIG leads Momentum by 30 points; RIG leads Quality by 9 points; SLB leads Risk Resilience by 9 points. Where the two split, the factor with the larger weight carries the result.
Which has more analyst upside, RIG or SLB?
Analyst price targets imply +15.9% upside for RIG and +24.3% for SLB, so the Street currently favors SLB. That points the opposite way to the AIQ Score, which favors RIG. The two are measuring different things: the model reads current fundamentals, valuation, trend and risk; the Street is pricing forward expectations. A divergence of this kind is either a contrarian opportunity or a sign the model is missing something the analysts have already priced — it is the single most useful row on this page to investigate. Analyst targets are expectations, not predictions, and dispersion matters as much as the midpoint.
Which is better value, RIG or SLB?
Neither name separates on the peer-relative Value factor. The two are level on Value. 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, RIG or SLB?
RIG 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, RIG or SLB?
RIG on the Momentum factor, by 30 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, RIG or SLB?
SLB is the more resilient of the two, so the other name carries the higher downside risk. SLB on Risk Resilience, by 9 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 RIG more profitable than SLB?
The profitability evidence is mixed: gross margin 74.3% vs 16.5%; operating margin 22.2% vs 13.4%; ttm roe -20.2% vs 11.8%. RIG leads on two measures and SLB on one measure, and there is no single profitability composite that resolves the split — which of the two reads as "more profitable" depends on whether you weight pricing power or operating leverage.
Is RIG's lead over SLB getting stronger or weaker?
RIG lead: Strengthening — the AIQ differential moved from 2 to 9 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 11 times in that window, most recently on 2026-09-15, when RIG moved ahead of SLB.
What would change the RIG vs SLB verdict?
The result is a state, not a forecast, so it changes when the underlying evidence changes. Concretely: SLB closes the Momentum gap — currently 30 points behind, the largest single contributor to RIG's edge; SLB's Bollinger Band Squeeze turns directional — it is neutral today and would confirm a change in trend; RIG'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 RIG and SLB?
RIG: 2 bullish / 2 bearish / 1 neutral, conflicted. SLB: 2 bullish / 0 bearish / 1 neutral. 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 RIG is Death Cross Active (bearish, long horizon). On SLB it is Golden Cross Active (bullish, 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.
