Here’s a clean, data‑driven breakdown of which TTCS components are contributing the most to the index’s uptrend, using the freshest available component and weight information from the search results.

📊 1. TTCS Is Driven by a Few Heavyweights

The S&P/TSX Capped Consumer Staples Index is extremely top‑heavy. Based on the iShares XST ETF (which directly tracks TTCS), the top weights are:

Company	Weight in TTCS	Impact on Index
Loblaw (L)	25.46%	#1 driver — any move in L heavily influences TTCS
Alimentation Couche‑Tard (ATD)	25.36%	#2 driver — nearly equal influence to Loblaw
Metro (MRU)	14.89%	#3 driver — meaningful but smaller
George Weston (WN)	12.75%	#4 driver — solid contributor
Saputo (SAP)	8.56%	Moderate contributor
Remaining 8 companies	~13% combined	Minimal impact

Together, L + ATD + MRU + WN = ~78% of the entire index.

So the uptrend is overwhelmingly driven by four stocks.

📈 2. Which Stocks Are Actually Rising?

From the TradingView component snapshot:

• Loblaw (L): Slight daily pullback in the snapshot, but long‑term trend remains strong.
• Alimentation Couche‑Tard (ATD): Also showed a small daily dip, but its multi‑year trend is one of the strongest in the TSX.
• Metro (MRU): Typically stable, defensive, and steadily rising.
• George Weston (WN): Historically strong performer tied to Loblaw.
• Saputo (SAP): More volatile, but improving after prior weakness.

Even if one of these names dips on a given day, the multi‑month trend for the group is upward — and because they dominate the index, TTCS rises with them.

🧩 3. Contribution Summary

Here’s the real impact hierarchy:

Major Drivers (≈80% of index movement)

1. Loblaw (L) — largest weight, steady long‑term uptrend
2. Alimentation Couche‑Tard (ATD) — strong multi‑year compounder
3. Metro (MRU) — stable, defensive, consistent
4. George Weston (WN) — benefits from Loblaw’s strength

Secondary Driver

5. Saputo (SAP) — smaller but still meaningful

Minimal Contributors

Everything else in TTCS combined contributes less than any one of the top two stocks.

🎯 Bottom Line

The TTCS uptrend is almost entirely explained by:

• Loblaw (L)
• Alimentation Couche‑Tard (ATD)
• Metro (MRU)
• George Weston (WN)

These four names account for nearly 80% of the index and have been in sustained long‑term uptrends, pulling TTCS upward with them.
