AIQ vs Wall Street
The model and the Street disagree here: AIQ favors TSM, analyst targets favor VIAV. That disagreement is the most useful thing on this page.
| Measure | TSM | VIAV | Note |
|---|---|---|---|
| Implied upside to target | +36.4% | +79.9% | VIAV has more room |
| Target dispersion | +34% | +9.4% | Lower is tighter analyst agreement |
| Consensus | Buy | Buy | Context, not a primary driver |
| Analysts covering | 7 | 3 | 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.

AIQ Signal Divergence
Only the signals that bear on the head-to-head. A conflicted name is carrying bullish and bearish rules at the same time — the technical evidence is not pointing one way.

Only VIAV
- ATR Expansion - Breakout Mode — neutral, volatility, short horizon (7.88%)
- Keltner Channel Breakdown — bearish, volatility, short horizon
Both carry 2 more signals that do not separate them: Golden Cross Active, MACD Bearish Crossover.
TSM 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.
Price and the AIQ Score both moved up over the latest session (price +1.6%, AIQ +1 points).
Neither the price nor the AIQ Score moved enough in the latest session to confirm or contradict the other (price +1.9%, AIQ 0 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.
- 1VIAV closes the Quality gap — currently 49 points behind, the largest single contributor to TSM's edge.
- 2VIAV's Keltner Channel Breakdown resolves — a bearish volatility rule currently active against it.
- 3TSM's conflicting signal state resolves bearish — it currently carries 1 bullish and 1 bearish rules at once.
- 4The narrowing continues — the lead has already given back 3 points over 30 sessions, and a further 16-point move would eliminate TSM's advantage entirely.

Is TSM or VIAV the better buy right now?
TSM carries the stronger systematic profile as of Oct 22, 2026, and the comparison is rated Competitive — 4 of 6 covered evidence groups agree. A Competitive rating means the two are close enough that your objective, not the score, should decide.

Which is better value, TSM or VIAV?

Which has stronger momentum, TSM or VIAV?
VIAV on the Momentum factor, by 5 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, TSM or VIAV?

What would change the TSM vs VIAV verdict?
The result is a state, not a forecast, so it changes when the underlying evidence changes. Concretely: VIAV closes the Quality gap — currently 49 points behind, the largest single contributor to TSM's edge; VIAV's Keltner Channel Breakdown resolves — a bearish volatility rule currently active against it; TSM's conflicting signal state resolves bearish — it currently carries 1 bullish and 1 bearish rules at once; the narrowing continues — the lead has already given back 3 points over 30 sessions, and a further 16-point move would eliminate TSM's advantage entirely.
What do the current signals say about TSM and VIAV?
TSM: 1 bullish / 1 bearish, conflicted. VIAV: 1 bullish / 2 bearish / 1 neutral, 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.

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.
