How AMGN Has Actually Traded Around Earnings

Over the last eight reported quarters, Amgen has beaten earnings-per-share estimates seven times, for an 88% beat rate. The average surprise on those beats has been 9.4%. That consistency on the bottom line would suggest an upward tendancy, and the numbers partly back that up: across those same quarters, the average five-day price move after earnings has been 2.95%, with the drift classified as “up.”

But the headline numbers hide a more complicated tape. In the most recent four quarters, every single report was a beat, yet two of them produced meaningful selling. On 2026-04-30, AMGN reported actual EPS of $5.15 versus an estimate of $4.77 — an 8% surprise — and the stock fell 4.75% the very next session and 4.96% over the next five trading days. On 2025-08-05, the company delivered a 14% surprise with actual EPS of $6.02 against an estimate of $5.28; the stock moved down 5.14% the next day and 5.03% over the following five days. The contrast is the other two quarters: 2026-02-03 saw an 11.8% beat send AMGN up 8.15% the next day and 7.7% over five days, while 2025-11-04’s 12.4% beat produced a 7.81% one-day gain and a 14.07% five-day run. So even when AMGN beats, the post-earnings drift has not reliably moved in the direction of the surprise.

Options-Flow Considerations for the August 4 Event

AMGN’s next scheduled earnings release is 2026-08-04 after the close, with the official consensus EPS estimate at $5.62. The stock’s current price is $376.04, and the 50-day EMA sits at $355.71. Heading into that close, the options market typically prices an event premium, meaning implied volatility is generally lifted relative to non-report weeks. The size of that lift reflects the expected move, dealer gamma positioning around the $376 area, and the balance between call and put flow.

Because the realized average five-day post-earnings drift is 2.95%, a trader can compare the implied move priced into the nearest-expiry straddle against that historical baseline. If short-dated implied volatility is cheap relative to the typical post-report range, option sellers face an asymmetric risk because an earnings surprise can gap the underlying faster than vol can expand. If it is rich, the market may already be demanding a premium for the uncertainty. Flow also matters after the print: when a beat coincides with heavy short-dated call positioning, delta-hedging flows can extend a rally; when the gap disappoints option holders, gamma unwinds can exaggerate downside. The 2026-08-04 report will therefore be shaped not only by the $5.62 EPS estimate but also by how crowded pre-event positioning has become.

What a Disciplined Trader Watches

Given AMGN’s recent history of “beat-and-sell,” a disciplined approach starts with tracking the gap against the surprise, not just the headline EPS number. The current snapshot shows RSI at 64.1, which is not formally overbought but reflects a market that has already moved. Price is 5.7% above the 50-day EMA of $355.71, so the pre-event setup is extended relative to its short-term trend. If AMGN announces above $5.62 and the stock reverses lower, that would echo the 2026-04-30 and 2025-08-05 patterns and suggest guidance, full-year commentary, or sector rotation is outweighing the earnings beat.

Traders also compare the implied event move to the average post-earnings drift of 2.95%. A setup where options imply substantially more than that historical drift can signal that the market is pricing a binary move, while a cheaper implied move can suggest muted expectations. Rather than front-running the direction before the 2026-08-04 close, many look for the first hour of price discovery the next morning, when the options market reprices volatility and overnight surprises become measured against the $5.62 official consensus.
