Analyst Views & Fundamentals

Analysts are divided on Thermo Fisher’s outlook. The simple average rating stands at 4.00, while the weighted performance-based rating is 0.00, indicating strong dispersion in views and poor historical accuracy from recent predictions. Notably, the lone analyst (William Blair’s Matt Larew) gave a "Buy" rating on August 19, 2025, but the firm has a 0.00% historical win rate and -2.76% average return on its TMO calls in the last 20 days.

This contrasts with TMO’s 8.31 internal diagnostic score (0-10) from our proprietary model, which highlights robust fundamentals:

• Revenue-MV: 7.19% (score: 2.00)
• Basic EPS YoY Growth: 9.83% (score: 3.00)
• Diluted EPS YoY Growth: 10.13% (score: 3.00)
• Rate of Return on Total Assets: 3.55% (score: 3.00)
• Cash-UP: 72.05% (score: 3.00)
• EBIT/Total Operating Revenue: 16.60% (score: 3.00)

The high scores on EBIT margins and earnings growth reflect TMO’s strong operational efficiency and resilience amid broader sector uncertainty.

Money-Flow Trends

Big money is flowing into Thermo Fisher, with inflow ratios across all sizes showing positive trends. The overall inflow ratio is 51.14%, indicating that more large-cap and institutional capital is entering than exiting. Specifically:

• Extra-large inflow ratio: 51.19%
• Large inflow ratio: 51.51%
• Medium inflow ratio: 50.67%
• Small inflow ratio: 49.82%

This suggests that institutional investors remain bullish despite a recent price drop of -2.07% in the last week. Retail investors appear slightly less optimistic, as small-cap inflows lag slightly behind the broader market.

Key Technical Signals

Thermo Fisher’s technical picture is mixed, with 4.66 internal diagnostic score (0-10) and a trend labeled "Weak technology, need to be cautious". Recent signals include:

• WR Overbought (score: 1.84): Overbought condition detected multiple times in the last 5 days (Aug 18–26). While this indicator shows a weak bias, it suggests caution as the stock could be overvalued in the short term.
• RSI Overbought (score: 7.72): A strong positive signal, with 80% historical win rate and 0.77% average return when this condition appears. It indicates potential upside, but with recent overbought readings, caution is warranted.
• MACD Death Cross (score: 4.41): A bearish signal was triggered on August 26, historically leading to an average -0.86% return with a 57.14% win rate. This suggests that short-term bearish momentum is building.

Recent chart patterns show WR Overbought as a recurring theme, with spikes on Aug 18, 20, 19, and 26, while RSI Overbought appeared on August 19. These conflicting signals highlight a volatile, directionless phase in the stock’s price action.

Conclusion

Thermo Fisher is in a mixed environment — strong fundamentals (8.31 score) and positive fund flows (7.99 score) contrast with weak technical indicators (4.66 score). The stock has seen conflicting signals over the past week, suggesting a possible consolidation period.

Actionable takeaway: Consider waiting for a pull-back or clearer directional momentum before entering, especially with the RSI and WR both showing overbought conditions. A close eye on earnings and macro news in the coming weeks could provide the clarity needed to decide whether to go long or wait.
