Historical Earnings Track Record and the Post-Earnings Drift Disconnect

Best Buy has beaten the official consensus in 7 of the last 8 reported quarters, an 88% beat rate, with an average earnings surprise of 5.9%. On the surface that suggests the company has consistently cleared the bar, but the price action tells a more nuanced story. Across those same eight quarters, the average 5-day price move in the trading days after earnings was -2.14%, classified as a “down” drift. That means the headline beat has not, on average, translated into sustained upward follow-through.

The last four reports make the disconnect concrete. On 2026-05-28, BBY reported $1.28 EPS versus a $1.23 estimate, a 4.1% beat; the stock rose 4.29% the next session but fell 5.02% over the next five days. On 2026-03-03, actual EPS was $2.61 against a $2.46 estimate, a 6.1% beat; the next-day gain was 2.18%, yet the five-day drift was -1.74%. On 2025-11-25, a 6.9% beat—$1.40 versus $1.31—produced a 1.66% one-day pop and a -6.63% five-day drawdown. Only 2025-08-28 bucked the pattern: a 5.8% beat on $1.28 versus $1.21 led to a 1.35% next-day move and a 4.83% five-day gain. Three of the last four beats were followed by negative five-day drift, so the historical playbook is not “beat and hold.”

Options-Flow Dynamics Ahead of the 2026-08-27 Report

The next scheduled report is 2026-08-27 before the open, with the current consensus EPS estimate at $1.34. With BBY at $85.41, the stock is well above its 50-day EMA of $74.39 and carries an RSI of 72.1, a setup that already reflects significant short-term momentum. That technical positioning matters for the options market because much of the market’s real expectation is expressed through implied volatility and positioning rather than the static consensus number.

Around earnings, that can translate into elevated near-term option premiums, directional call/put skew, and concentration risk at nearby strikes. If the options flow is pricing in a large expected move, traders are effectively paying for a volatility event rather than a pure direction bet. After the report, the typical post-earnings implied-volatility collapse can erode option value quickly even if the stock moves the “right” way at the headline level. Sector context—Consumer Cyclical/Specialty Retail—adds another layer, since discretionary spending commentary can drive moves that exceed what the EPS beat or miss alone would imply.

What a Disciplined BBY Earnings Trade Watches

Given the historical pattern, a disciplined approach focuses on how the market prices the event, not just whether BBY beats the $1.34 consensus. The data shows beats have usually been met with selling pressure over the following week, so the five-day drift is at least as important as the next-day gap. Watch whether the stock’s pre-earnings run extends the distance above the 50-day EMA—as of now that gap is $11.02—which can raise reversion risk after a euphoric open.

Use the prior quarter-by-quarter drift as a baseline, not a forecast: the average five-day post-earnings move has been -2.14%, and three of the last four reports posted negative five-day returns after beating. Also compare any post-report move against the prior actual EPS figures of $1.28, $2.61, $1.40, and $1.28, because year-ago and sequential comparisons are what analysts and algorithms react to fastest. Risk management starts with recognizing that the 88% beat rate and the negative average drift can coexist.
