About Tesla, Inc.
Tesla designs, manufactures, and sells electric vehicles, energy storage systems, and solar products. Under CEO Elon Musk, Tesla grew from a niche EV maker into one of the world's most valuable companies, driven by production scaling, brand loyalty, and market sentiment around the EV transition.
The Story
Tesla passed our initial screening filters — price, volume, and volatility in Stage 1, then trend alignment and momentum checks in Stage 2 — on 207 trading days across our 14-year backtest window. That's further than most stocks get. Only around 50 stocks per day typically survive Stage 2. But Tesla never cleared Stage 3 scoring. On its best days — like June 2020, when the stock was in the middle of a powerful uptrend — Tesla's combined score reached approximately 20 out of 100. The MONITOR threshold (the lowest signal level) requires 50. Tesla was 30 points short. Even accounting for sentiment scoring — which backtests exclude, since AI news analysis only runs in live daily screening — Tesla would have gained at most 10 points from positive coverage, bringing the peak to roughly 30. Still 20 points short of MONITOR.

Why TSLA Was Missed
TSLA had strong price momentum but failed our fundamental quality checks. Here's the scoring breakdown on its best day.
Quality Score: 16/60
3 of 9 quality signals fired. Only technical trend signals fired — all fundamental signals (profitability, balance sheet, growth) read zero.
Entry Score: 4/20
2 of 7 entry signals fired. The highest-weighted entry signals were not present.
Scores shown are approximate peak values from 14-year backtest (2012–2025). Sentiment scoring (0–10) is not included in backtests — AI news sentiment analysis is only available in live daily screening. How scoring works →
What This Teaches
Tesla is a perfect illustration of what our system is designed to do — and what it deliberately filters out. The scoring system requires fundamental quality AND technical momentum to align before assigning a signal. Tesla had the momentum but not the fundamentals. Through much of the 2012–2025 backtest window, Tesla carried high debt, inconsistent profitability, and financial metrics that didn't meet the thresholds our system uses for balance sheet strength, earnings quality, and revenue consistency. This is a feature, not a bug. Our portfolio significantly outperforms the S&P 500 across 14 years precisely because it's selective. Stocks that pass on momentum alone — without fundamental confirmation — are filtered out. Some, like Tesla, go on to deliver spectacular returns. But requiring both signals produces better risk-adjusted outcomes across hundreds of stocks over 14 years. Missing Tesla is the cost of not missing on the majority of momentum-only stocks that don't deliver.
