Comparing TSLA vs PLTR on 15 Metrics — The Agent's Verdict Surprised Me
Key Takeaway
My AI agent ran a head-to-head comparison of Tesla and Palantir across 15 financial metrics with weighted scoring — PLTR won on growth-adjusted value, triggering a 5% portfolio rebalance that I wouldn't have made on gut instinct.
The Problem
I hold both TSLA and PLTR. Both are high-conviction positions. Both are volatile. Both have massive narratives.
The problem with narrative-driven stocks: you stop looking at the numbers. You know the story. The story is compelling. So when someone asks "should you hold more TSLA or more PLTR?" you answer with the story, not the data.
I caught myself doing this during a portfolio review. "TSLA is the larger position because... well, it's Tesla." That's not a thesis. That's brand loyalty disguised as investment analysis.
I needed a framework that compares any two positions on hard metrics, weights them by what I actually care about, and gives me a score that doesn't care about the narrative.
The Solution
Hari, my investment advisor agent, runs a US Stock Analysis skill with a head-to-head comparison template. Fifteen metrics across valuation, growth, profitability, momentum, and risk — each weighted by my investment style. The output is a comparison table, narrative analysis, and composite score.
No stories. Just numbers. Then I decide if the numbers change my mind.

The narrative analysis:
PLTR outscores TSLA significantly on growth-adjusted valuation. While TSLA's P/E (68.4) appears cheaper than PLTR's (124.2), the PEG ratio tells a different story: PLTR's earnings growth rate justifies more of its premium. PLTR's profitability metrics are dominant — 81% gross margin vs 18% reflects a pure software model versus hardware manufacturing. The 148% 52-week run creates momentum risk, but the lower max drawdown suggests PLTR's volatility is more upside-skewed.
Recommendation: Consider rebalancing 5% from TSLA to PLTR. The growth-adjusted value case is materially stronger for PLTR at current prices.
The Results
| Metric | Before | After | Impact |
|---|---|---|---|
| TSLA allocation | 25% of equities | 20% | -5% |
| PLTR allocation | 25% of equities | 30% | +5% |
| Portfolio Sharpe (30-day after) | 1.42 | 1.58 | +11.3% |

| Bias detected | Brand loyalty to TSLA | — | Corrected |

The PEG ratio was the metric that changed my mind. I was anchored on P/E, which favored TSLA. But PEG — which adjusts for growth — flipped the picture. PLTR's higher P/E is justified by materially higher earnings growth. The agent surfaced what my confirmation bias was hiding.
Try It Yourself

alpha-vantageskill for stock data - Define your comparison metrics and category weights
- Run head-to-head comparisons on any two positions
- Adjust weights to match your investment style (value-heavy, growth-heavy, etc.)
- Use the composite score as input, not as gospel — the agent informs, you decide
The best investment decisions happen when you force yourself to look at numbers you'd rather ignore. The agent doesn't have preferences. That's the point.
Your gut has a position. The numbers might not agree. Listen to the numbers first.
