The Week
Amphenol finished the week down 47.52% at $82.78. The S&P 500 added 0.09% over the same stretch, leaving the stock roughly 47.61 percentage points behind the benchmark. It was a week of sharp reversals. On Monday 31 August the stock opened at $156.41 and closed at $158.55. Tuesday 1 September pushed higher to an intraday high of $163.29 before closing at $163.18. By Wednesday 2 September it had still held near $160.08, but Thursday 3 September opened all the way down at $80.82 and spent the session between $79.33 and $82.16, closing at $82.07. Friday 4 September kept the stock in a tight range and closed at $82.78. Most of the weekly loss came from that Thursday gap-down, with full-week amplitude at 53.68%.
Key Events
The week’s main story was Amphenol’s 31 August approval of a 2-for-1 stock split, executed through a stock dividend. On 2 September, reports said AI data-centre orders had hit record highs, briefly testing the $164 level, but trading diverged sharply in the second half of the week. The stock fell intraday on both 2 September and 3 September, and on 3 September it touched a 52-week low. By 4 September, reports confirmed the split had been completed. Goldman Sachs kept its buy rating on 31 August. There were no other material company filings this week; the split and the AI data-centre order momentum defined the narrative.
Analyst Ratings
Across 17 covering institutions, 11 rate the stock a buy, 4 rate it overweight and 2 rate it hold, with no sell or underweight ratings. The consensus rating is strong buy, with a consensus target price of $99.15, implying about 19.77% upside versus the last price. Target prices range from $85 to $115, a fairly tight band. Within the electronic-components industry, Amphenol ranks 2nd out of 22 companies, near the top of the peer group.
The Week Ahead
On the macro side, the US NFIB small business optimism index lands on 8 September, followed on 10 September by initial jobless claims, PPI data, 10-year Treasury auction results and existing home sales. For Amphenol itself, the next earnings event is fiscal Q3 2026 results on 28 October, which will show whether the AI data-centre order strength carries through and how the stock split affects per-share figures.
In Short
Amphenol’s stock fell sharply this week even as the company approved a split and reported record AI data-centre orders, creating tension between price action and the news flow. The analyst side remains supportive, with a strong buy consensus and a target price roughly 20% above spot, while the latest session’s flows show heavier selling pressure among medium and small orders. Valuation is also elevated, with P/E around 39.69x and P/B around 13.18x. The key question ahead is whether post-split liquidity and the AI order run-rate hold up when third-quarter earnings arrive.
