TBIL is not without a case — it holds the better momentum 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 SHY or TBIL the better buy right now?
SHY carries the stronger systematic profile as of Sep 5, 2026, and the comparison is rated Fragile — 1 of 4 covered evidence groups agree. A Fragile rating means the conclusion is sensitive: the AIQ gap is narrow at 1 points. Treat the lead as provisional.
Why does the AIQ Score favor SHY over TBIL?

Which is better value, SHY or TBIL?

Which has stronger growth, SHY or TBIL?
Growth figures are not covered for both names. 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, SHY or TBIL?
TBIL on the Momentum factor, by 5 points. Momentum carries 25% of 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, SHY or TBIL?
SHY is the more resilient of the two, so the other name carries the higher downside risk. SHY on Risk Resilience, by 6 points. The Risk Resilience factor weights 15% of the composite; position sizing usually responds to it more usefully than the buy/avoid decision does.
Is SHY more profitable than TBIL?
Margin data is not comparable for both names in the current snapshot.
Is SHY's lead over TBIL getting stronger or weaker?
SHY lead: Stable — the AIQ differential has held near 1 points over 30 sessions. This is measured from 120 daily comparison snapshots between 2026-04-22 and 2026-09-03. The lead has changed hands 8 times in that window, most recently on 2026-08-24, when TBIL moved ahead of SHY.
What would change the SHY vs TBIL verdict?
The result is a state, not a forecast, so it changes when the underlying evidence changes. Concretely: TBIL closes the Quality gap — currently 6 points behind, the largest single contributor to SHY's edge; TBIL's Death Cross Active resolves — a bearish trend rule currently active against it; SHY's conflicting signal state resolves bearish — it currently carries 1 bullish and 5 bearish rules at once; a regime shift changes factor weighting — the composite weights Quality and Value at 30% each, so a rotation toward either would move the result most.
What do the current signals say about SHY and TBIL?
SHY: 1 bullish / 5 bearish / 1 neutral, conflicted. TBIL: 1 bullish / 4 bearish / 2 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. The most decision-relevant rule on SHY is Death Cross Active (bearish, long horizon). On TBIL it is Death Cross Active (bearish, long horizon).

How this comparison is scored
The Algovestiq AIQ Score composites four factors — Quality (30%), Value (30%), Momentum (25%) and Risk (15%). 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.
