Broadcom (AVGO.US) is scheduled to report its fiscal year 2026 first quarter (Q1) results on March 4. Current market expectations indicate that the chip giant's earnings per share (EPS) could reach $2.03, representing a 26.9% increase year-over-year. Revenue is projected to be $19.27 billion, a 29.2% rise compared to the same period last year. This robust performance outlook is already partially reflected in the current stock price. However, if the disclosed key metrics surpass market expectations, it could trigger a further upward movement in the share price. Conversely, if the figures fall short of expectations, it may lead to downward pressure on the stock. This dynamic of "expectation verification-stock price reaction" is a typical characteristic of earnings reporting periods in mature capital markets.

Wall Street anticipates that the company's revenue growth will drive a year-over-year increase in profits when it announces the quarterly results for the period ending in the first quarter of fiscal 2026. While this widely known consensus is crucial for assessing the company's profitability, a key factor influencing its near-term stock price movement is the gap between the actual results and these expectations. Although the sustainability of immediate price changes and future earnings expectations will primarily depend on management's discussion of business conditions during the earnings call, estimating the probability of an EPS beat remains valuable.

In theory, a positive or negative Earnings ESP (Earnings Surprise Prediction) reading indicates a potential deviation of actual earnings from the consensus estimate. However, the model's predictive power is statistically significant only for positive readings. A positive Earnings ESP is a strong predictor of an earnings beat, especially when combined with a Zacks Rank of #1 (Strong Buy), #2 (Buy), or #3 (Hold). Research shows that stocks with this combination have nearly a 70% probability of delivering a positive surprise, and a solid Zacks Rank can actually enhance the predictive power of the Earnings ESP.

It is important to note that a negative Earnings ESP reading does not necessarily predict an earnings miss. Research indicates that for stocks with a negative Earnings ESP and/or a Zacks Rank of #4 (Sell) or #5 (Strong Sell), it is difficult to confidently predict whether they will beat earnings expectations.

In the case of Broadcom, the Most Accurate Estimate is below the Zacks Consensus Estimate, suggesting that analysts have recently turned more bearish on the company's earnings prospects. This results in an Earnings ESP of -0.84%. On the other hand, the stock currently holds a Zacks Rank of #2. Therefore, this combination makes it difficult to conclude that Broadcom will definitively beat the consensus EPS estimate.

Beating or missing earnings estimates is not the sole determinant of a stock's price movement. Many stocks decline even after an earnings beat due to other factors that disappoint investors. Similarly, some stocks may rise despite a miss if fueled by an unexpected catalyst. Nevertheless, betting on stocks that are expected to beat estimates can indeed improve the odds of success.

Based on the current metrics, Broadcom does not appear to be a strong candidate for a positive earnings surprise. However, when deciding whether to invest in or avoid the stock ahead of the earnings report, investors should also consider other relevant factors.
